Fail-Safe/Backup Function

If a problem which interferes with the continuous safe operation of the transaxle is identified, the TCM records a diagnostic trouble code in memory, all solenoids are turned off, and the module is switched to limp-in mode.

When limp-in mode is started, the transaxle is locked in 2nd gear if a drive gear had previously been selected. Meanwhile, if P, R or N range was selected, operation is as usual. If the ignition key is turned to OFF and then back to ON again, limp-in mode is canceled (a record is retained).
