This series features TechTIPS articles frequently referred to by Techline. This month’s feature is from
December 2022.
STARLINK TELEMATICS – COMM CHECK, TEST CALLS, REMOTE SERVICES
REQUESTS, FAILED CALLS 15
The purpose of this TechTIP is to share some best practices for Gen 2 and Gen 3 Telematics service
procedures. It is also to stress the importance of contacting Techline when encountering uncertainty or
difficulty with any generation of Starlink Telematics. As a reminder to Technicians the best way to ensure
they get the information needed to diagnose Telematics concerns efficiently is to complete QMRs with a
high level of detail to ensure a steady flow of information to the field.
Critical: The SSM4 should only be connected to the vehicle when reviewing data or using
Work Support. The SSM4 should not be connected to the vehicle during the Comm Check,
Provisioning after a Comm Check, during a VOLTE call and Remote Service testing.
Please perform the procedures below before contacting Techline for one of the concerns listed.
The Comm Check Procedure
Press the “i” button for 2 seconds to perform the Comm Check and then connect the SSM4.
Navigate to the Telematics data monitor and confirm the “Subscription Status” PID changes to
“Unsubscribed” and the Telematics LEDs are off (if the vehicle does not have a subscription), or
changes to “Subscribed” and the GREEN telematics LED is illuminated (if the vehicle has a current
subscription).
Note: The SSM4 should not be connected while trying to perform the Comm Check, test calls, or
Provisioning. Starlink Telematics is very sensitive to the SSM4 connection. The SSM4 may be
probing for data and can cause interference which may cause a race condition and Comm Check
failure.
The Test Call Procedure
A Technician can press the “i” button on any Gen 2 or Gen 3 vehicle and connect to the Starlink
call center. Once connected to an operator, the Technician can request a remote door unlock or
remote engine start (RES) to verify telematics operation further. More information about Remote
Service testing can be found in TSB 15-266-20.
Note: Services available for testing can vary and are based on the customer’s subscription plan.

STARLINK TELEMATICS – COMM CHECK, TEST CALLS, REMOTE SERVICES
REQUESTS, FAILED CALLS (CONTINUED) 15
Test Call Procedure after DCM Replacement
After a Technician has replaced the DCM, verifying the operation of the “i” button and Remote
Services is necessary. If the procedure below is not followed, “i” button calls may not connect to
a Starlink operator.
1. DCM has been replaced, and the Comm Check has been completed.
2. Turn the ignition off and wait ten minutes.
3. Turn the ignition on, press the “i” button to connect to the Starlink call center, and complete
Telematics repair verification testing.
CRITICAL: Failure to cycle ignition power and wait ten minutes after DCM replacement
could result in “i” button calls failing. This behavior may lead Technicians to determine that
the DCM replacement did not repair the customer’s concern or introduce a new concern
to the vehicle.
Note: The SSM4 should not be connected to the vehicle when trying to use the “i” button to
connect with a Starlink Operator. Having the SSM4 connected may cause the “i” button call or
Remote Service request to fail.
The Comm Check fails
In almost all cases, the Comm Check will complete on the first attempt. The Comm Check may fail
in rare circumstances, and the “Subscription Status” PID returns to “Factory” mode.
After a Comm Check failure please check for the following conditions that can prevent the Comm
Check from completing.
1. There are current Telematics DTCs.
2. The Telematics antenna may have a fault in the circuit. (When in “Factory mode” the Signal
strength PID will always read 0%)
3. All Telematics fuses have been visually and electrically inspected for faults.
4. The SSM4 (or any aftermarket dongle) was plugged into the OBDII connector while the
Comm Check was performed.
5. Inspect for any aftermarket devices in the vehicle.
If none of the above conditions are found with the car, please perform the workaround below
before contacting Techline for further assistance.
November 2023 TechTIPS Page 5 of 19
Continued on the next page
WORKAROUND: The Technician must use the SSM4 to confirm the “Subscription Status” is
“Unsubscribed” or “Subscribed” in the Telematics data monitor before releasing the vehicle. The
Comm Check has failed if the subscription status is “FACTORY” or “COMM”. If the Comm Check
is confirmed to have failed, follow the procedure below.
• Disconnect the SSM4 from the vehicle.
• Turn the ignition off and wait 5 minutes.
• Turn the ignition on and wait 3 minutes, doing nothing to the car during this time.
• Press the “i” button for 2 seconds to perform the Comm Check.
• Wait 2 minutes, then connect the SSM4 and verify the “Subscription Status” in live data.
• If the Comm Check has not been completed after performing this procedure twice, contact
Techline for more assistance.SOS or “i” button calls fail to connect to an operator.
If a customer reports a concern of the “i” button or “SOS” button not connecting to a Starlink
Operator or the Technician experiences this condition during testing, perform the workaround
below before contacting Techline.
WORKAROUND: If a test call exhibits no connection to an operator or an error message when
performing the “SOS” or “i” button push, the technician should first:
• Disconnect the 12V under-hood battery for 15 minutes.
• Ensure the SSM4 is not connected to the car.
• Reconnect the 12V under-hood battery.
• Turn the ignition on and wait 3 minutes, doing nothing to the vehicle during this time.
• Perform another test of the “i” button.
• If this procedure fails to rectify the “no VOLTE” call concern, contact Techline for support.
A test call using the SOS/”i” button fails, Remote Service request fails post enrollment or
after DCM replacement.
Upon customer enrollment or DCM replacement, if remote service requests fail to complete,
perform the workaround below before contacting Techline.
This workaround is a suitable general procedure to clear transient conditions with the DCM or
its connection to the network. Technicians may want to incorporate this workaround into their
Telematics diagnostic method.

REQUESTS, FAILED CALLS (CONTINUED) 15
November 2023 TechTIPS Page 6 of 19
Continued on the next page
WORKAROUND: If the technician experiences a provisioning failure, they should:
• Disconnect the 12V under-hood battery for 15 minutes.
• Ensure the SSM4 is not connected to the car.
• Reconnect the 12V under-the-hood battery.
• Turn the ignition on and wait 3 minutes, doing nothing to the vehicle.
• Connect the SSM4, using live data to verify the “Subscription Status” now shows “Subscribed”
to confirm the provisioning failure is no longer present.
• Verify operation by placing an “i” button call to connect to an operator.
• Ask the operator to send a remote door to unlock the vehicle to verify the operation of the
remote services.
• If this procedure fails to rectify the provisioning failure concern, contact Techline for support.

15 Microphone Inoperative, Telematics DCM Comm Check Failure and RES inop
Techline has received an increased number of cases where the Remote Engine Start is inoperable,
Comm Check after a DCM replacement is not possible, as well as inoperable or intermittent microphone
operation. Below is an overview of what has been found and the best process for repair.
Concern: A significant number of DCM (Data Communication Module) replacements have been
performed due to misdiagnosed DCM failures. The actual root cause of the issue is a blown ACC
(Accessory) fuse, often this can be triggered by a faulty USB-connected device.
Symptoms:
• Microphone inoperable
• Telematics Comm Check failure
• RES inoperable
Affected Components:
• ACC power for the DCM
• Rear USB hub
• Wireless charger (if equipped)
Troubleshooting Steps:
1. Verify the ACC fuse for the DCM is intact and has B+ on both sides of fuse. An open fuse
indicates a circuit fault. If an open fuse is found continue to step 2.
If the fuse is intact, see: July 2023 TechTIPS for continued microphone troubleshooting. If
the concern is Comm Check failure, contact Techline for assistance. If the Concern is RES
operation, see 15-282-21R.
2. Inspect the center console and rear USB hubs for any signs of damage or contamination (the
front USB hub is not powered by this fuse).
3. Disconnect all USB devices from the rear USB hub, and/or the rear USB hub itself. Make any
necessary repairs to the circuit.
4. Replace the blown ACC fuse. Perform the Telematics test call using the “i” button and ensure
the Starlink operator can hear you. If the concern is Comm Check failure, verify at this point that
the Comm Check completes. Verify the RES now operates.
Preventive Measures:
1. Avoid connecting incompatible or damaged USB devices to the vehicle.
2. Regularly inspect the USB hub for signs of damage or contamination.
3. Ensure USB devices are properly connected and secured.

Microphone Inoperative, Telematics DCM Comm Check Failure and RES inop
(CONTINUED) 15
Emphasis on Misdiagnosis: The high frequency of misdiagnosed DCM failures highlights the
importance of thorough troubleshooting. A blown ACC fuse can easily mimic the symptoms of a faulty
DCM, leading to unnecessary component replacements.
By prioritizing the ACC fuse check in these situations, technicians can efficiently identify the root
cause and implement an appropriate solution, preventing unnecessary expenses and downtime.
Note: The fuse numbers below are for the Telematics system. It is always recommended to
verify the other circuits that are powered by any fuse for the model vehicle being serviced.

15 EyeSight HALT Codes 41, A0 and CC
When diagnosing Eyesight concerns, it is helpful to understand the setting criteria of the HALT codes
to determine if there is a system fault or normal characteristics of how the system operates. HALT
codes do not always indicate a system failure. They are there to label why the system temporarily
stopped. Some of the more common HALT codes to see are 41, A0, and CC.
HALT Code 41 is on systems with both EBB (Electric Brake Booster) and EyeSight Ver4. It has been
found that the VDC initial diagnosis may not be completed if the brake is continuously depressed
after the engine has been started. Normal operation to complete this check is to start the engine and
release the brake pedal. This allows the initial VDC diagnosis to complete and the system to operate
normally.
HALT Code A0 does not necessarily indicate a fault with the CAN system. In most scenarios, this
will populate due to cycling the ignition to the on position, waiting and then starting the vehicle. Note
the description below found in the Service Manual that this can be a normal condition. However,
depending on the concern, a battery inspection may be necessary.
HALT Code CC This code may be the most common to see. This code, in most cases is due to the
camera lenses not having a clear image ahead. This can be due to several everyday scenarios such as
bad weather (heavy rain, fog, frost, snow, etc.) direct sunlight or oncoming traffic high-beam lights. In
some cases, aftermarket windshields or improperly mounted windshield devices that block the view
of the camera can cause the system to stay off and will populate this as a result.

B28A1, U1P07, U1P08, U1C07, U1C08C 15
Techline has been receiving an increase of calls about numerous codes being present after a module
replacement. It is always critical to read and follow all steps listed in the “Removal” and “Installation”
directions in STIS when replacing any module in the vehicle. There are steps that have been added to
the “Installation” directions on STIS when replacing modules, when these steps are not followed there
will be multiple DTCs set after a new module is installed. There are two previous TechTIPS covering
this subject with relation to replacing Stereo EyeSight cameras, July 2022 and April 2023.
There are now many modules that will need a programming procedure to be performed after
replacement, a few examples are the Stereo EyeSight Camera, the Data Communication Module
(DCM), the Transmission Control Module (TCM
), the Vehicle Dynamics Control Module (VDC). There
may be other modules that will also need the “Unit Registration” or “Immobilizer Registration” to be
completed.
Some modules may have their own listing in the Immobilizer Registration section, again it is critical to
read and follow all steps of the “Installation” directions in STIS.

To determine if “Unit Registration” needs to be performed, navigate to STIS for the vehicle being
serviced, find the “Installation” directions for that module. This step will be listed. Below are a few
examples from STIS instructing a Technician to perform the “Unit Registration”.
IT IS CRITICAL TO READ AND FOLLOW ALL STEPS OF MODULE
