< DTC/CIRCUIT DIAGNOSIS >[7AT: RE7R01B]
MAIN POWER SUPPLY AND GROUND CIRCUIT
YES >> GO TO 5.
NO >> Repair or replace damaged parts.
5.CHECK INTERMITTENT INCIDENT
Refer to GI-40, "
Intermittent Incident".
Is the inspection result normal?
YES >> Replace the control valve & TCM. Refer to TM-182, "Exploded View".
NO >> Repair or replace damaged parts.
6.DETECT MALFUNCTIONING ITEM (PART 1)
Check the following.
 Harness for short or open between battery positive term inal and A/T assembly vehicle side harness connec-
tor terminal 2. Refer to PG-11, "
Wiring Diagram - BATTERY POWER SUPPLY -".
Battery
 10A fuse (No.38, located in the fuse, fusible link and relay box). Refer to PG-141, "
Fuse and Fusible Link
Arrangement".
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI-40, "Intermittent Incident".
NO >> Repair or replace damaged parts.
7.CHECK HARNESS BETWEEN IPDM E/ R AND A/T ASSEMBLY (PART 1)
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector.
3. Check continuity between IPDM E/R vehicle side harness connector terminal and A/T assembly vehicle
side harness connector terminals.
Is the inspection result normal?
YES >> GO TO 8.
NO >> Repair or replace damaged parts.
8.CHECK HARNESS BETWEEN IPDM E/ R AND A/T ASSEMBLY (PART 2)
Check continuity between A/T assembly vehicle side harness connector terminal and ground.
Is the inspection result normal?
YES >> GO TO 9.
NO >> Repair or replace damaged parts.
9.DETECT MALFUNCTIONING ITEM (PART 2)
Check the following.
 Harness for short or open between ignition switch and IPDM E/R. Refer to PG-89, "
Wiring Diagram - IGNI-
TION POWER SUPPLY -".
 Ignition switch
 10A fuse (No.55, located in the IPDM E/R). Refer to PG-143, "
Fuse, Connector and Terminal Arrangement".
 IPDM E/R
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI-40, "Intermittent Incident".
