Ignition Shut Down Relay (For Antitheft): Testing and Inspection



INSPECTION

Measure the interrupt relay resistance between terminals (indicated in the table below) when connecting terminal No.3 to battery positive terminal and terminal No.1 to battery ground terminal.










If NG, replace the interrupt relay.

IMPORTANT: Do not connect the terminals to battery positive terminal and ground terminal incorrectly. If this happens, replace the interrupt relay.
