CHART 1: NO COMMUNICATION WITH THE ECM

Diagnosis Procedure

INFOID:0000000000912033

1.

INSPECTION START

Ensure that CONSULT-III is not causing the malfunction by trying to establish dialogue with an ECM on
another vehicle. If the CONSULT-III is not at malfunction, and dialogue cannot be established with any other
ECM on the same vehicle, the cause could be a suspected ECM interfering on the CAN communication line.
Check the voltage of the battery and carry out the operations necessary to obtain a voltage which is to specifi-
cation (9.5 V < U battery < 17.5 V).

>> GO TO 2.

2.

CHECK CAN COMMUNICATION

Perform trouble diagnosis on the CAN communication line using CONSULT-III. Refer to

LAN-59, "CAN Com-

munication Signal Chart"

.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace harness or connector.

3.

CHECK ECM GROUND

Check the ECM earth (ground) point on the side strut tower.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace ground connection.

4.

CHECK ECM POWER SUPPLY AND GROUND CIRCUIT

Check ECM power supply and ground circuit. Refer to

EC-1317, "Diagnosis Procedure"

.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace harness or connector.

5.

CHECK DATA LINK CONNECTOR CIRCUIT

Check for the presence of 12 V on terminal 16 with ignition switch OFF, 12 V on terminal 8 with ignition switch
ON and an earth (ground) on terminals 4 and 5 of the data link connector.
Repair if necessary.

Is the inspection result normal?

YES

>> INSPECTION END
