Disconnect the 22P connector from the multiplex control unit, driver's, then remove the control unit from the driver's under-dash fuse/relay box.
Inspect the connectors and connector terminals to be sure they are all making good contact.
- If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to next step 3 .
NOTE: If the shift lock solenoid clicks when the ignition switch is turned ON (II) while depressing the brake pedal with the shift lever in the [P] position, the shift lock system is OK. If the shift lever cannot be shifted from P position, test the A/T gear position switch.
With the control unit still disconnected from its connectors and the fuse/relay box, make these input tests.
- If a test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 4 .
