Diagnosis Procedure

INFOID:0000000011277546

1.

CHECK CONNECTOR

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Check the following terminals and connectors for damage, bend and loose connection (unit side and con-

nector side).

-

Distance sensor

-

Harness connector E152

-

Harness connector M31

-

BCM

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the connector of BCM.

2. Check the continuity between the BCM harness connector terminals.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Check the harness and repair the root cause (CAN communication circuit 2 side). Refer to 

LAN-

71, "Diagnosis Procedure"

.

3.

CHECK HARNESS FOR OPEN CIRCUIT

1. Connect the connector of BCM.

2. Disconnect the connector of distance sensor.

3. Check the resistance between the distance sensor harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 4.

NO

>> Repair the distance sensor branch line.

4.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the distance sensor. Refer to 

DAS-153, "DISTANCE SEN-

SOR : Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the distance sensor. Refer to 

DAS-170, "Removal and Installation"

.

YES (Past error)>>Error was detected in the distance sensor branch line.

NO

>> Repair the power supply and the ground circuit.

Diagnosis Procedure

INFOID:0000000011277547

1.

CONNECTOR INSPECTION

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Disconnect all the unit connectors on CAN communication circuit 1.

4. Check terminals and connectors for damage, bend and loose connection.
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the data link connector terminals.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Check the harness and repair or replace (if shield line or fuse block (J/B) is short) the root cause.

3.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the data link connector and the ground.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Check the harness and repair or replace (if shield line or fuse block (J/B) is short) the root cause.

4.

CHECK ECM AND BCM TERMINATION CIRCUIT

1. Remove the ECM and the BCM.

2. Check the resistance between the IPDM E/R terminals.

3. Check the resistance between the BCM terminals.

Is the measurement value within the specification?

YES

>> GO TO 5.

NO

>> Replace the ECM and/or the BCM.

5.

CHECK SYMPTOM

Connect all the connectors. Check if the symptoms described in the “Symptom (Results from interview with

customer)” are reproduced.

Reproduced>>GO TO 6.

Non-reproduced>>Start the diagnosis again. Follow the trouble diagnosis procedure when past error is

detected.

6.

CHECK UNIT REPRODUCTION

Perform the reproduction test as per the following procedure for each unit.

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Disconnect one of the unit connectors of CAN communication circuit 1.

NOTE:

ECM and BCM have a termination circuit. Check other units first.

4. Connect the battery cable to the negative terminal. Check if the symptoms described in the “Symptom

(Results from interview with customer)” are reproduced. 

NOTE:

Although unit-related error symptoms occur, do not confuse them with other symptoms. 

Inspection result

Reproduced>>Connect the connector. Check other units as per the above procedure.

Non-reproduced>>Replace the unit whose connector was disconnected.
