Circuit/System Testing

NOTE:

If there are multiple modules not original to the vehicle and are not new correctly configured service parts, SPS may not be able to properly read or recover the vehicle odometer value. Follow government rules and documentation (including vehicle identification) regarding inaccurate/unknown odometer values.

Instrument Cluster is Showing "----" (Dashes, Correcting VIN mismatch - odometer is still unlocked.)

  1. Verify the vehicle odometer lock status with a scan tool. The reading should be Inactive.
    • If the reading is Active, go to correcting VIN mismatch - odometer is locked.
  2. Using the scan tool, verify the BCM VIN matches the vehicle VIN placard. If the VIN does not match, reprogram the BCM.
  3. Using the scan tool, verify the instrument cluster VIN matches the vehicle VIN placard. If the VIN does not match, reprogram the instrument cluster.
    • If the instrument cluster is still displaying "----" (dashes), replace the P16 instrument cluster.
