M/T Reverse Lockout System Circuit Troubleshooting

Start the engine, and check the Malfunction Indicator Lamp (MIL).

NOTE: DTC P0045, P0403, P2008, and P245A is indicated by circuit open.

Does the MIL come on?

YES	-	Troubleshoot the DTC, and recheck.■
NO	-	Go to Step 2 .

Turn the ignition switch OFF.

Disconnect the reverse lockout solenoid 2P connector.

Turn the ignition switch ON (II).

Measure the voltage between the reverse lockout solenoid 2P connector terminal No. 2 and body ground.

Is there battery voltage?

YES	-	Go to Step 6 .
NO	-	Repair open in the wire between the PGM-FI main relay 2 and reverse lockout solenoid 2P connector terminal No. 2.■

Turn the ignition switch OFF.

At reverse lockout solenoid side, connect the No. 2 terminal of the reverse lockout solenoid to the battery positive terminal, and connect the No. 1 terminal to the battery negative terminal. Check that the reverse lockout solenoid operates.

Does the reverse lockout solenoid operate properly?

YES	-	Go to Step 8 .
NO	-	Replace the reverse lockout solenoid. ■

Disconnect ECM connector No. 1 (96P).

Check for continuity between reverse lockout solenoid 2P connector terminal No. 1 and body ground.

Is there continuity?

YES	-	Repair short in the wire between the reverse lockout solenoid terminal No. 1 and the ECM connector No. 1 terminal No. 51.■
NO	-	Go to Step 10 .

Connect the reverse lockout solenoid 2P connector terminal No. 1 to body ground with a jumper wire.

Check for continuity between ECM connector No. 1 terminal No. 51 and body ground.

Is there continuity?

YES	-	If necessary, update the ECM if it does not have the latest software, or substitute a known-good ECM, then recheck. If the symptom/indication goes away with a known-good ECM, replace the original ECM. ■
NO	-	Repair open in the wire between the reverse lockout solenoid terminal No. 1 and the ECM connector No. 1 terminal No. 51.■
