Fail-Safe Chart

FAIL-SAFE CHART
1. FAIL-SAFE CHART
This function minimizes the loss of the ECT functions when a malfunction occurs in each sensor or solenoid.





Fail-safe function:
If either of the shift solenoid valve circuits has an open or short failure, the ECM turns the other shift solenoid ON and OFF in order to shift into the gear positions shown in the table.
In case of a short circuit, the ECM stops sending current to the short circuit solenoid.
Even if starting the engine again in the fail-safe mode, the gear position remains in the same position.

HINT:
^ [arrow down]: Condition in the electrical malfunction is shown above "[arrow down]".
^ [arrow down]: Condition in fail-safe mode is shown below "[arrow down]".
^ E/B: Engine brake.
