Diagnosis Procedure

INFOID:0000000011506774

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).

-

A/C auto amp. (With auto A/C)

-

Harness connector M127 (With auto A/C)

-

Harness connector M125 (With auto A/C)

-

Front air control (Without auto A/C)

-

BCM

Is the inspection result normal?

YES

>> GO TO 2. (With auto A/C)

YES

>> GO TO 3. (Without auto A/C)

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-

265, "Diagnosis Procedure"

.

3.

CHECK HARNESS FOR OPEN CIRCUIT

1. Connect the connector of BCM (With auto A/C).

2. Disconnect the connector of A/C auto amp. (With auto A/C) or front air control (Without auto A/C).

3. Check the resistance between the A/C auto amp. (With auto A/C) or front air control (Without auto A/C)

harness connector terminals.

-

With auto A/C

-

Without auto A/C

Is the measurement value within the specification?

YES

>> GO TO 4.

NO

>> Repair the A/C auto amp. (With auto A/C) or front air control (Without auto A/C) branch line.

4.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the A/C auto amp. (With auto A/C) or front air control (With-

out auto A/C). Refer to the following.

• Automatic air conditioning:

.

Is the inspection result normal?

YES (Present error)>>Replace the A/C auto amp. (With auto A/C) or front air control (Without auto A/C).

Refer to the following.

• Automatic air conditioning: 

HAC-103, "Removal and Installation"

.

• Manual air conditioning: 

HAC-182, "Removal and Installation"

.

YES (Past error)>>Error was detected in the A/C auto amp. (With auto A/C) or front air control (Without auto

A/C) branch line.

NO

>> Repair the power supply and the ground circuit.

Diagnosis Procedure

INFOID:0000000011506776

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.
