NO >> Repair or replace damaged parts.

3.CHECK TCM POWER CIRCUIT

1. Turn ignition switch ON.

2. Check voltage between TCM harness connector F16 terminal 46, 48, 45, 47 and ground.

Is the inspection result normal? YES >> GO TO 6.

NO >> GO TO 4.

4.CHECK HARNESS BETWEEN TCM AND IPDM E/R AND BETWEEN TCM AND BATTERY (PART 1)

Is the inspection result normal? YES >> GO TO 5.

NO >> Repair or replace damaged parts.

5.CHECK HARNESS BETWEEN TCM AND IPDM E/R AND BETWEEN TCM AND BATTERY (PART 2)

Check continuity between TCM harness connector F16 terminal 45, 46, 47, 48 and ground.

Is the inspection result normal? YES >> Check the following.

• 10A fuse (No. 34, located in IPDM E/R) • 10A fuse [No. 11, located in fuse block (J/B)] • Ignition switch. Refer to PG-74.

NO >> Repair or replace damaged parts.

6.DETECT MALFUNCTIONING ITEMS

Check TCM connector pin terminals for damage or loose connection with harness connector.

Is the inspection result normal? YES >> Replace TCM. Refer to TM-430, "Exploded View".

NO >> Repair or replace damaged parts.
