CALIBRATION INFORMATION











REQUIRED SSTS:

INSPECTION PROCEDURES:

1. Inspect and note the engine oil level.
2. If oil level is low, inspect for leak source and repair. If NO leaks are present, proceed to step 3.
3. Add engine oil as necessary and then proceed to the ECM reprogramming procedure.

REPAIR PROCEDURES:







1. Check for the Authorized Modifications Label affixed to the vehicle in the location shown in Figure 1. Confirm if the ECM (PCM) calibration has been updated. If the calibration ID listed is NOT the latest ECM (PCM) calibration - go to step 2.
2. Flash reprogram the ECM (PCM).

NOTE
- The GR8 Battery Diagnostic Station MUST be used in Power Supply Mode to maintain battery voltage at 13.5 volts while flash reprogramming the vehicle.
- For details on how to use the GR8 Battery Diagnostic Station, refer to the GR8 Instruction Manual located on the Technical Information System (TIS), Diagnostics - Battery.


Follow the procedures outlined in TSB2758, "Techstream ECU Flash Reprogramming Procedure", and flash the ECM (PCM) with the NEW calibration file update.

3. Start the engine and warm it up to normal operating temperature before test driving.
4. Install the Authorized Modifications Label.
A. Using a permanent marker, enter the following information on the label:
- ECM part number [Refer to the Parts Information section for the CURRENT PART NUMBER]
- Calibration ID(s) [Refer to the Calibration Identification Chart for the NEW CALIBRATION ID]
- Dealer Code
- Repair Date
- Change Authority [This TSB number]

B. Affix the Authorized Modifications Label to the vehicle at the location shown in Figure 1. The Authorized Modifications Label is available through the MDC, P/N 00451-00001-25.

5. Start the engine and warm it up to normal operating temperature before test driving.
