Diagnosis Procedure
1.CHECK CONNECTOR
Turn the ignition switch OFF.
Disconnect the battery cable from the negative terminal.
Check the following terminals and connectors for damage, bend and loose connection (unit side and connector side).
Models without automatic drive positioner
ECM
Harness connector E30
Harness connector M1
Models with automatic drive positioner
ECM
Harness connector E29
Harness connector B10
2.CHECK HARNESS FOR OPEN CIRCUIT
Disconnect the connector of ECM.
Check the resistance between the ECM harness connector terminals.

3.CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the ECM. Refer to EC-157, "Diagnosis Procedure".
