ECM BRANCH LINE CIRCUIT
Diagnosis ProcedureINFOID:0000000001334403
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).
-ECM
- Harness connector E7
- Harness connector M69
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.
- Diesel engine models
- Gasoline engine models
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 the following.
