CAN COMMUNICATION CIRCUIT

Inspection result

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 system.

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.

Diagnosis Procedure

INFOID:0000000009760124

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 (connector side

and harness side).

-

Harness connector E7

-

Harness connector M69

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the following harness connectors.

-

IPDM E/R

-

Harness connectors E7 and M69

2. Check the continuity between the IPDM E/R harness connector and the harness connector.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the main line between the IPDM E/R and the harness connector E7.

3.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

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

Is the inspection result normal?

YES (Present error)>>Check CAN system type decision again.

YES (Past error)>>Error was detected in the main line between the IPDM E/R and the data link connector. 

NO

>> Repair the main line between the harness connector M69 and the data link connector.

Diagnosis Procedure

INFOID:0000000009760126

1.

CHECK CONNECTOR

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Check the terminals and connectors of the ECM for damage, bend and loose connection (unit side and

connector side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1. Disconnect the connector of ECM.

2. Check the resistance between the ECM harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the ECM branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the ECM. Refer to 

EC-157, "Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the ECM. Refer to 

EC-465, "Removal and Installation"

.

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

NO

>> Repair the power supply and the ground circuit.

Diagnosis Procedure

INFOID:0000000009760127

1.

CHECK CONNECTOR

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Check the terminals and connectors of the ABS actuator and electric unit (control unit) for damage, bend

and loose connection (unit side and connector side).
