Shifting is performed in combination with ON and OFF position of shift solenoids controlled by ECM. If an open or short circuit occurs in any shift solenoid, ECM reverts to fail-safe mode. ECM turns SL solenoid (also called lock-up) off at same time. DTCs are output when a open or short circuit occurs. Possible causes are:
- No. 1 and/or No. 2 solenoid circuit.
- No. 1 and/or No. 2 solenoid malfunction.
- ECM malfunction.
