Ignition Switch-ST (M/T)

ECU System:

To test the Ignition Signal to the ECU, locate pins #4 and #9 of ECU connector C50-3, and test for the presence of battery voltage with the ignition key in the "on" position. Both pins should have battery voltage present.

NOTE: To test pins do not remove the connector from the ECU, instead insert a straight pin or needle from the back side of the connector to access the pin.

Ignition Switch-ST Circuit:

To inspect the ignition "Start Signal", proceed as follows.

HARNESS TEST
1. Disconnect the ECU connector and turn the key to the START position.

2. Using a voltmeter, check the voltage between the ECU harness connector terminal 8 and ground.

Voltage:
8 or more Volts.

3. Turn the key to the OFF position and check for continuity between ECU harness connector terminal 2 and ground.

Continuity:
Should exist.


If any of the previous tests produce unsatisfactory results, the harness will need to be repaired or replaced. Once repairs have been completed, road test the vehicle to confirm that the repair has corrected the problem.
