Ignition Switch: Testing and Inspection

Ignition switch "START" and "ON" signals can be checked at ECU terminals 1C and 1I respectively.

While cranking, terminal 3B voltage should be approximately 10V. With ignition "ON" terminal voltage should be 0V.

With ignition "ON" terminal 2J voltage should be approximately 12V. With ignition "OFF" terminal voltage should be 0V.
