Shift Lock System/Reverse Lock System Circuit Troubleshooting

Shift Lock System/Reverse Lock System Circuit Troubleshooting
1. Press the brake pedal.
Are the brake lights ON?
YES - Go to step 2.
NO - Repair faulty brake light circuit.
2. Connect the HDS to the DLC. Check engine speed and throttle position in the A/T data list.
Is the engine speed at idle, and TPS about 0.5 V?
YES - Go to step 3.
NO - Repair engine speed or throttle position input.
3. Select SHIFT LOCK SOL TEST in MISC. TEST MENU, then carry out shift lock solenoid function test.
Does the shift lock solenoid work properly?
YES - System circuit is OK. Check the mechanism, if necessary.
NO - Go to step 4.
4. Remove the center console cover.
5. Disconnect the shift lock solenoid connector.
6. Turn the ignition switch ON (II).





7. Measure the voltage between shift lock solenoid connector terminal No. 1 and body ground.
Is there battery voltage?
YES - Go to step 6.
NO - Check for blown No. 32 (7.5A) fuse in the under-dash fuse/relay box. If the fuse is OK, repair open in the wire between the shift lock solenoid connector and the under-dash fuse/relay box.
8. Shift to the [P] position, and press the brake pedal. Do not press the accelerator.





9. Measure the voltage between shift lock solenoid connector terminals No. 1 and No. 2 while pressing the brake pedal.
Is there battery voltage?
YES - Check the shift lock mechanism. If the mechanism is OK, replace the shift lock solenoid.
NO - Check for poor connection or loose E2 terminal at the PCM, and check for an open in the wire between PCM connector terminal E2 and shift lock solenoid connector. If the connection and wire are OK, substitute a known-good PCM and recheck.
