M/T Reverse Lockout System Circuit Troubleshooting

1.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.n


NO - Go to 2.


2.Turn the ignition switch OFF.

3.Disconnect the reverse lockout solenoid 2P connector.

4.Turn the ignition switch ON (II).

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

 

Is there battery voltage?


YES - Go to 6.


NO - Repair open in the wire between the PGM-FI main relay 2 and reverse lockout solenoid 2P connector terminal No. 2.n

6.Turn the ignition switch OFF.

7.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 8.


NO - Replace the reverse lockout solenoid.n

8.Disconnect ECM connector No. 1 (96P).

9.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.n


NO - Go to 10.


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

 

11.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.n


NO - Repair open in the wire between the reverse lockout solenoid terminal No. 1 and the ECM connector No. 1 terminal No. 51.n
