Operation CHARM: Car repair manuals for everyone.

Backup Mode

If a major system failure occurs which could affect safety or damage the Transmission under normal Vehicle operation, the diagnostic system detects the fault and overrides the Powertrain Control Module ([1][2]PCM).

The "CHECK TRANS" light flashes to alert the driver, and the Transmission must be manually shifted.

Shifts are firmer to prevent Clutch slip and consequent wear. The fault should be corrected as soon as possible.
