Check For Intermittent Problems

SET TEST MODE

- With the ignition switch off, using a jumper wire, connect the terminals TE2 and E1 of the DLC2.

- Start the engine and check to see the malfunction indicator lamp to go off.


PERFORM A SIMULATION TEST

- Apply vibration to and pull lightly on the wire harness, connector or terminals in the circuit indicated by the malfunction code.

- In this test, if the malfunction indicator lamp lights up, it indicates that the place where the wire harness, connector or terminals being pulled or vibrated has faulty contact. Check that point for loose connections, dirt on the terminals, poor fit or other problems and repair as necessary.

HINT: After cancelling out the diagnostic trouble code in memory and set the test mode, if the malfunction indicator lamp does not go off after the engine is started, check thoroughly for faulty contact, etc., then try the check again. If the malfunction indicator lamp still does not go off, check and replace ECM.
