On-Board Diagnostic System

Fail Safe Functions (Codes 81-86):





The judgement conditions for fail-safe items are the same as the judgement conditions for the related diagnosis codes. If these related diagnosis codes are output 4 times in a row, a fail-safe item is recorded.

Accordingly, if a fail-safe item is output, the diagnostic trouble codes will also be output at the same time.

In addition, fail-safe codes lock the transaxle in 3rd or 2nd gear. Fail-safe will be cancelled if the ignition switch is turned OFF. the diagnostic trouble codes will remain.
