1. Turn ignition switch OFF.
2. Disconnect TCM harness connector and CVT unit harness connector.
3. Check continuity between TCM harness connector F16 terminal 33 and ground.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace damaged parts.
4.CHECK HARNESS BETWEEN TCM AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR) (PART 1)
Check continuity between TCM harness connector F16 (A) terminal 33 and input speed sensor (primary speed sensor) harness connector F8 (B) terminal 2.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace damaged parts.
5.CHECK HARNESS BETWEEN TCM AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR) (PART 2)
Check continuity between TCM harness connector F16 terminal 33 and ground.
Is the inspection result normal? YES >> GO TO 10.
NO >> Repair or replace damaged parts.
6.CHECK HARNESS BETWEEN IPDM E/R AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR) (POWER) (PART 1)
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector F10.
3. Check continuity between IPDM E/R harness connector F10 terminal 58 and input speed sensor (primary speed sensor) harness connector F8 terminal 3.
Is the inspection result normal?
YES >> GO TO 7.
NO >> Repair or replace damaged parts.
7.CHECK HARNESS BETWEEN IPDM E/R AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR) (POWER) (PART 2)
Check continuity between IPDM E/R harness connector F10 terminal 58 and ground.
Is the inspection result normal? YES >> Check the following.
• Harness for short or open between ignition switch and IPDM E/R
• 10A fuse (No. 34, located in IPDM E/R) • Ignition switch
NO >> Repair or replace damaged parts.
8.CHECK HARNESS BETWEEN TCM AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR) (SENSOR GROUND) (PART 1)
1. Turn ignition switch OFF.
2. Disconnect TCM connector.
3. Check continuity between TCM harness connector F16 terminal 25 (A) and input speed sensor (primary speed sensor) harness connector F8 (B) terminal 1.
Is the inspection result normal? YES >> GO TO 9.
NO >> Repair or replace damaged parts.
9.CHECK HARNESS BETWEEN TCM AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR) (SENSOR GROUND) (PART 2)
1. Disconnect CVT unit harness connector.
2. Check continuity between TCM harness connector F16 terminal 25 and ground.
Is the inspection result normal? YES >> GO TO 10.
NO >> Repair or replace damaged parts.
10.CHECK CVT UNIT CIRCUIT
Check continuity between CVT unit harness connector F46 terminal 19 and ground.
Is the inspection result normal? YES >> GO TO 11.
NO >> Repair or replace damaged parts.
11.CHECK TCM
1. Replace same type TCM. Refer to TM-430, "Exploded View".
2. Connect each connector.
3. Perform “DTC CONFIRMATION PROCEDURE”. Refer to TM-313, "DTC Logic".
Is “P0715 INPUT SPD SEN/CIRC” detected? YES >> Replace input speed sensor (primary speed sensor). Refer to TM-437, "Removal and Installation".
NO >> Replace TCM. Refer to TM-430, "Exploded View".
12.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.
