Turn ignition switch OFF.

2.

Disconnect ICC sensor integrated unit connector.

3.

Turn ignition switch ON.

4.

Check voltage between ICC sensor integrated unit harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace ICC sensor integrated unit power supply harness or fuse.

3.

CHECK GROUND CIRCUIT FOR ICC SENSOR INTEGRATED UNIT

1.

Turn ignition switch OFF.

2.

Check continuity between ICC sensor integrated unit harness connector and ground.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Repair or replace ICC sensor integrated unit ground harness.

PARK/NEUTRAL POSITION SWITCH (M/T)

PARK/NEUTRAL POSITION SWITCH (M/T)

Description

INFOID:0000000001606944

Park/neutral position switch provides input signals to ECM, which transmits the data to ICC sensor integrated
unit with CAN communication. 
ICC sensor integrated unit performs the following controls via park/neutral position switch. 
• Rejects any attempt to set ICC system when M/T shift knob is set at neutral position. 
• Cancels ICC system when M/T shift knob is set to neutral position. 

Component Function Check

INFOID:0000000001606945

1.

CHECK OPERATION OF PARK/NEUTRAL POSITION SWITCH

With CONSULT-III

With “ICC” of “Data Monitor”, check if “NP SW SIG” operate normally.

Is the inspection result normal?

YES

>> INSPECTION END.

NO

>> Go to 

CCS-82, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000001606946

1.

CHECK PARK/NEUTRAL POSITION SWITCH CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect park/neutral position switch connector and ECM connector.

3.

Check continuity between park/neutral position switch harness connector and ECM harness connector. 

4.

Check continuity between park/neutral position switch harness connector and ground. 

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

REPAIR OR REPLACE HARNESS BETWEEN PARK/NEUTRAL POSITION SWITCH AND ECM

Repair or replace harness between park/neutral position switch and ECM.

>> GO TO 10.

3.

CHECK PARK/NEUTRAL POSITION SWITCH GROUND CIRCUIT

Check continuity between park/neutral position switch harness connector and ground.

REPAIR OR REPLACE HARNESS BETWEEN PARK/NEUTRAL POSITION SWITCH AND GROUND

Repair or replace harness between park/neutral position switch and ground.

>> GO TO 10.

5.

CHECK PARK/NEUTRAL POSITION SWITCH

Check park/neutral position switch. Refer to 

CCS-83, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 7.

NO

>> GO TO 6.

6.

REPLACE PARK/NEUTRAL POSIRION SWITCH

Replace park/neutral position switch. 

>> GO TO 10.

7.

PERFORM SELF-DIAGNOSIS OF ECM

1.

Perform self-diagnosis of ECM.

2.

Check if DTC is detected. Refer to 

EC-552, "DTC Index"

.

Is any DTC detected?

YES

>> GO TO 8.

NO

>> GO TO 9.

8.

REPAIR OR REPLACE APPLICABLE ITEM

Repair or replace the applicable item identified by the self-diagnosis result.

>> GO TO 10.

9.

REPLACE ICC SENSOR INTEGRATED UNIT

1.

Replace ICC sensor integrated unit.

2.

Adjust laser beam aiming. Refer to 

CCS-7, "LASER BEAM AIMING ADJUSTMENT : Special Repair

Requirement (Preparation)"

.

>> GO TO 10.

10.

CHECK ICC SYSTEM
