Calibration ID Information
NOTE
There are different calibration files for vehicles with and without transaxle oil coolers. In order to
determine the configuration of your vehicle, shine a flashlight into the left front bumper cover vent.
If the vehicle is equipped with a cooler, it will be easily visible.

Repair Procedure
1. Prepare the vehicle for reflash.
NOTE
This procedure will pressurize the brake actuator and prevent the ABS pump from running
during the reflash procedure.
A. Prior to vehicle shut down perform the following steps:
• Place the vehicle in the ready on position.
• Place the transaxle in the P range.
• Engage parking brake .
B. Depress the brake pedal fully 2 times within 2 seconds.
C. Release brake pedal.

2. Check for the Authorized Modifications Label affixed to the vehicle in the location shown in
Figure 2. Confirm if the HV ECU and ECM (PCM) calibrations have been updated. If the
calibration IDs are NOT the latest calibrations — go to step 2.

Repair Procedure (Continued)
3. Flash Reprogram the HV ECU and 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 – Tools & Equipment – Battery Diagnostics.
Follow the procedures outlined in Service Bulletin No. T-SB-0012-13, “Techstream ECU Flash
Reprogramming Procedure,” and flash the ECM (PCM) with the NEW calibration file update.
NOTE
• Anytime the HV ECU is reprogrammed, the engine ECM (PCM) MUST also be
reprogrammed, even if the engine ECM (PCM) has the “New Calibration ID.”
• If ONLY the engine ECM (PCM) Calibration ID matches the “Current Calibration ID” shown
in the Calibration Information section in this bulletin, proceed with flash reprogramming.
• If BOTH the engine ECM (PCM) and HV ECU Calibration IDs match the “New” calibration IDs
shown in the Calibration Information section, this vehicle has already been reprogrammed.
Refer to TIS for diagnostic procedures applicable to any stored DTCs.
4. Start the engine and warm it up to normal operating temperature before test driving.
5. Test drive the vehicle to confirm proper vehicle operation (and proper laser cruise control
operation, if equipped).
6. Confirm that the O2 sensor monitor reads “complete”.
7. 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 NEW PART NUMBER]
• Calibration ID(s) [Refer to the Calibration Information section for the NEW
CALIBRATION ID]
• Dealer Code
• Repair Date
• Change Authority [This bulletin number]
B. Affix the Authorized Modifications Label to the vehicle at the location shown in Figure 2. The
Authorized Modifications Label is available through the MDC, P/N 00451-00001-LBL.

8. Calibration update is complete.
NOTE
The effect of the NEW calibration may become more apparent after several days of driving as
the ECM (PCM) “learned values” are re-established from the customer’s driving.
