Retrieving Fault Codes

1. Place the shift lever in neutral.

2. Set the parking brake.

To Retrieve Active Codes: Start with the key in the ON position. Turn the key OFF and ON two times within five seconds ending with the key in the ON position. After five seconds, the gear display begins flashing two-digit fault codes. If there are no active codes the gear display will show code 25, followed by PD (Product Diagnostic mode). The vehicle will not start in PD mode. You must turn vehicle key OFF and allow the system to power down to exit PD mode before restarting.

After five seconds, the gear display begins flashing two-digit fault codes. If no codes are active, the gear display will flash code 25 (no codes).
