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 ENGINE" light comes on and the "CHECK TRANS" light flashes to alert the driver, and the transmission must be manually shifted as follows: Select lever position / Gear Ratio Selected- D / 4 (Fourth)
- Manual 3 / 4 (Fourth)
- Manual 2 / 3 (Third)
- Manual L / 1 (First)
- R / Reverse
Shifts are firmer to prevent clutch slip and consequent wear. The fault should be corrected as soon as possible.
