FAIL-SAFE FUNCTION REFERENCE TABLE
The judgement conditions for fail-safe items are the same as the conditions for the
diagnosis codes.If these related diagnosis codes are output 4 times in succession, a fail-safe item
is recorded.
Accordingly, if a fail-safe item is output, the diagnostic trouble codes will also be output at the sa me
time.
In addition, fail-safe codes lock the transaxle in or gear. Fail-safe will be if the ignition
switch is turned to OFF. The diagnostic trouble cod es will remain.
