Diagnosis Procedure

1.CHECK PRIMARY SPEED SENSOR POWER CIRCUIT

1. Turn ignition switch OFF.
2. Disconnect primary speed sensor connector.
3. Turn ignition switch ON.
4. Check voltage between primary speed sensor harness connector terminal and ground. 

Is the inspection result normal?

YES >> GO TO 2.

NO >> GO TO 6.

2.CHECK PRIMARY SPEED SENSOR GROUND CIRCUIT

Check continuity between primary speed sensor harness connector terminal and ground. 

Is the inspection result normal?

YES >> GO TO 3.

NO >> Repair or replace malfunctioning parts.

3.CHECK CIRCUIT BETWEEN PRIMARY SPEED SENSOR AND TCM (PART 1)

1. Turn ignition switch OFF.
2. Disconnect TCM connector.
3. Check continuity between primary speed sensor harness connector terminal and TCM harness connector terminal.                                                                                     

Is the inspection result normal?

YES >> GO TO 4.

NO >> Repair or replace malfunctioning parts.

4.CHECK CIRCUIT BETWEEN PRIMARY SPEED SENSOR AND TCM (PART 2)

Check continuity between primary speed sensor harness connector terminal and ground. 

Is the inspection result normal?

YES >> GO TO 5.

NO >> Repair or replace malfunctioning parts.

5.CHECK TCM INPUT SIGNALS

1. Connect all of disconnected connectors.
2. Lift the vehicle.
3. Start the engine.
4. Check frequency of primary speed sensor.

Is the inspection result normal?

YES >> Check intermittent incident. Refer to GI "Intermittent Incident".

NO >> Replace primary speed sensor. TM "Removal and Installation".

6.CHECK CIRCUIT BETWEEN IPDM E/R AND PRIMARY SPEED SENSOR (PART 1)

1. Disconnect IPDM E/R connector.
2. Check continuity between IPDM E/R harness connector terminal and primary speed sensor harness connector terminal.                                                

6.CHECK CIRCUIT BETWEEN IPDM E/R AND PRIMARY SPEED SENSOR (PART 1)

1. Disconnect IPDM E/R connector.
2. Check continuity between IPDM E/R harness connector terminal and primary speed sensor harness connector terminal.                                                                                         

Is the check result normal?

YES >> GO TO 8.

NO >> Repair or replace malfunctioning parts.

8.DETECT MALFUNCTIONING ITEMS

Check the following items:

• Harness open circuit or short circuit between ignition switch and IPDM E/R. Refer to PG "Wiring Diagram - Ignition Power Supply -".
• 10A fuse (No.49, IPDM E/R). Refer to PG "IPDM E/R Terminal Arrangement".
• IPDM E/R

Is the check result normal?

YES >> Check intermittent incident. Refer to GI "Intermittent Incident".

NO >> Repair or replace malfunctioning parts.
