| SUBJECT: | Measurement of Dark Current (Standby Current Draw) |
INTRODUCTION:
This Service Information Bulletin provides additional information for the diagnostic procedures concerning measurement of Dark Current (a.k.a. Standby Current). Customer concerns of batteries going dead over a period of time should be diagnosed using this procedure after any obvious contributing factors have been eliminated. The following information is provided to help avoid unnecessary parts replacement. The following is to be used as supplemental information and is not intended to replace the more detailed procedures supplied in the applicable Service Manual.
SERVICE PROCEDURE / INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
When a dead battery condition is experienced due to excessive Dark Current (Standby Current) draw and the source is traced to the VDC and/ or Power Rear Gate Control Module, it is IMPORTANT to follow the procedures outlined in the applicable Service Manual: Engine > STARTING/CHARGING SYSTEM > Battery > INSPECTION, in conjunction with the additional diagnostic information provided below.
NOTE:
- These Flow Charts are to be used in addition to the applicable Service Manual procedures.
- Prepare the vehicle with the hood up, door(s) open, and the rear gate open. Confirm all associated latches are in the “latched” position. This will help reduce unwanted battery resets.
- ALWAYS set the power supply voltage to 13.5 Volts when using Power Supply Mode.
NEVER turn the ignition switch on when charging at voltages 15 Volts or higher.
- The Trouble trees below should only be used if excessive dark current is identified AFTER waiting the appropriate time outlined in the Service Manual.
NOTE 1) Troubleshooting Tree for Dark Current (Standby Current) draw from VDC system.
NOTE 2) How to check resistance between EPB switch terminals.
- Confirm the ignition is switch OFF:
- Disconnect the EPB switch connector, and check if Dark Current decreases. If Dark Current decreases by disconnecting the EPB switch connector, replace EPB switch and continue diagnosis.
- Check resistance between terminals per the illustrations below.
Required Tool: DVOM
| Switch Position | Terminal No. | Standard |
| Neutral | 1-2
4-5 |
1MΩ and higher |
| 1-5
2-4 |
Less than 1Ω |
NOTE 3) How to check resistance between harness connector terminals for EPB Switch:
- Check the resistance between terminals per the illustrations below.
No. 1 – No. 2
No. 4 – No. 5
Specification: 1MΩ or more
NOTE 4) Troubleshooting Tree for excessive Dark Current draw from Power Rear Gate system:
NOTE 5) How to check resistance between terminals for Courtesy Switch.
- Check the resistance between the terminals specified in the charts below.
| Terminal No. | Inspection Conditions | Specification |
| 7 to 8 | Open | Less Than 1 Ω |
| 7 to 8 | Half | Less Than 1 Ω |
| 7 to 8 | Full | 1MΩ or More |
| Terminal No. | Inspection Conditions | Specification |
| 5 to 4 | Open | Less Than 1 Ω |
| Half | Less Than 1 Ω | |
| Full | 60 MΩ or More |
IMPORTANT NOTE: Whenever reconnecting the ground cable terminal to the battery sensor, torque to 7.5Nm (5.5ft.-lbs. or 66inch-lbs.) while supporting the sensor with the other hand as outlined in the applicable Service Manual under: STARTING/CHARGING SYSTSEMS > Battery Sensor.
