| SUBJECT: | ECM Reprogramming Availability for DTCs P0017 & P0019 Diagnostic Procedures for DTCs P0016, P0017, P0018 and P0019 |
INTRODUCTION
This Bulletin announces a diagnostic procedure and the availability of updated ECM reprogramming files to address DTCs P0017 and P0019. The diagnostic procedure is also applicable to DTCs P0016 and P0018.
COUNTERMEASURE IN PRODUCTION
A logic change was incorporated into production in mid-December, 2012 starting with the following VINs:
| MODEL | TYPE | STARTING VIN NUMBER |
| Impreza and XV Crosstrek | 4-Door | D*019203 |
| 5-Door | D*826233 |
SERVICE PROCEDURE / INFORMATION
NOTE: The Flow Charts on pages 4 (Intake) and 5 (Exhaust) summarize the Service Procedures.
- Be sure to confirm the latest SSMIII software version number, 1.36.50.7 dated January, 2013 (or later) has been installed before performing this procedure. Without it, data for Variable Valve Timing (VVT) Exhaust Initial Position Learning Values #1 and #2 will not be available.
- If the VIN of the vehicle is before the countermeasure, the VVT Learning Values will not be accessible until the ECM is reprogrammed with the latest PAK file as outlined in the table on page 3. Reprogramming procedures can be accessed from the SSMIII User Guide by clicking on “Help” in the toolbar at the top of the Main Menu screen.
- Connect the SSMIII to the vehicle.
- The current CID number of the ECM must be verified using the table on 3 to determine whether or not it needs to be reprogrammed before proceeding with the following steps.
- From the Main Menu, select the following options:
- All Other Models
- Each System Check
- Engine Control System
- Current Data Display & Save
Scroll to the bottom of the Current Data Display list. The last four items will be the VVT Intake and Exhaust Learning Values #1 and #2 as shown in the EXAMPLE below. (*CA = Crankshaft Angle Degrees)
| VVT initial Position Learning Value #1 | 61.3 | *CA |
| VVT initial Position Learning Value #2 | 59.2 | *CA |
| VVT Ex initial Position Learning Value #1 | 87.9 | *CA |
| VVT Ex initial Position Learning Value #2 | 88.7 | *CA |
For the INTAKE, the chart above shows values within the Specified Limits (number crankshaft angle degrees) which are a MINIMUM of 50 and a MAXIMUM of 70. Check the SSMIII data for VVT Advance Angle Amount as shown below.
| VVT Adv. Ang. Amount R | 0 | deg |
| VVT Adv. Ang. Amount L | 0 | deg |
With the engine at idle and at operating temperature, this value must be “0”. If confirmed to be “0”, proceed with the remaining steps on the INTAKE Flow Chart. If not “0”, diagnose and repair the VVT system per the Service Manual.
For the EXHAUST, the formula shown below must be used to determine if an ECM replacement is needed. Check the SSMIII data for Exhaust VVT Retard Angle as shown below. The specified range for this value is “0” +/- 10 degrees.
| Exh. VVT Retard Ang. R | 0 | deg |
| Exh. VVT Retard Ang. L | 0 | deg |
First, collect the following values from the SSMIII:
- A= Exhaust VVT Retard Angle Value, read with the engine at idle and at operating temperature (This value may be a positive or negative number.)
- B= VVT Exhaust Initial Position Learning Value
- Formula: C = A + B – 90 (The 90 value in the formula represents the midpoint of the Specified Limit range.)
Does the value of C = “0” +/- 10 (degrees)?
- Yes– Perform Inspection Mode and if no DTCs reset, the car is repaired.
- No– Replace the ECM then follow the remaining steps on the Flow Chart.
| #1: A = -3 B = 80 | -3 + 80 – 90 = -13 (C) so, ECM replacement is required. |
| #2 A = 2 B = 99.7 | 2 + 99.7 – 90 = 11.7 (C) so, ECM replacement is required. |
| #3 A = 2 B = 95 | 2 + 95 – 90 = 7 (C) In this case, “C” is within the range of +/- 10 degrees. Perform Inspection Mode per Service Manual and if no DTCs reset, repair is complete. |
- If the ECM is determined to be OK, clear the memory and perform Inspection Mode to confirm no DTCs reset. If P0016, P0017, P0018 or P0019 reset, diagnose per the applicable Service Manual. If no DTCs reset, the vehicle is repaired.
- If the ECM needs to be replaced, install the latest part number available then verify the CID number is the latest available as shown on the chart below. If the new ECM installed is not the latest (NEW) part number, update it with the appropriate PAK file as listed below. Following reprogramming, confirm the CID then matches the NEW CID NUMBER as listed on the chart below.
