4.CHECK IPDM E/R OUTPUT SIGNAL
1. Connect IPDM E/R harness connector.
2. Disconnect BCM harness connector.
3. Check voltage between electronic steering column lock harness connector and ground.
Is the inspection result normal? YES >> Replace electronic steering column lock.
NO >> GO TO 5
5.CHECK ELECTRONIC STEERING COLUMN LOCK CIRCUIT-II
1. Check continuity between electronic steering column lock harness connector M32 (A) terminal 3 and IPDM E/R harness connector E18 (B) terminal 32.
2. Check continuity between electronic steering column lock harness connector M32 (A) terminal 3 and ground.
Is the inspection result normal? YES >> GO TO 6
NO >> Repair harness or connector.
6.CHECK INTERMITTENT INCIDENT
Refer to GI-42, "Intermittent Incident".
>> Inspection End.
7.CHECK BCM OUTPUT SIGNAL
1. Turn ignition switch OFF.
2. Disconnect electronic steering column lock harness connector and IPDM E/R harness connector E5.
3. Check voltage between electronic steering column lock harness connector and ground.
Is the inspection result normal? YES >> GO TO 9
NO >> GO TO 8
8.CHECK ELECTRONIC STEERING COLUMN LOCK CIRCUIT-I
1. Disconnect BCM harness connector M122.
2. Check continuity between BCM harness connector M19 (A) terminal 86 and electronic steering column lock harness connector M32 (B) terminal 8.
3. Check continuity between BCM harness connector M19 (A) terminal 86 and ground.
Is the inspection result normal?
YES >> GO TO 11
NO >> Repair harness or connector.
9.CHECK IPDM E/R OUTPUT SIGNAL
1. Connect IPDM E/R harness connector.
2. Disconnect BCM harness connector.
3. Check voltage between electronic steering column lock harness connector and ground.
Is the inspection result normal? YES >> Replace electronic steering column lock.
NO >> GO TO 10
10.CHECK ELECTRONIC STEERING COLUMN LOCK CIRCUIT-II
1. Check continuity between electronic steering column lock harness connector M32 (A) terminal 8 and IPDM E/R harness connector E18 (B) terminal 33.
2. Check continuity between electronic steering column lock harness connector and ground.
Is the inspection result normal? YES >> GO TO 11
NO >> Repair harness or connector.
11.CHECK INTERMITTENT INCIDENT
Refer to GI-42, "Intermittent Incident".
>> Inspection End.
