Starter Interrupt System Circuit

Turn ignition off and disconnect ATS ECU connector. Unlock either driver's or passenger's door using key. Put shift lever into Neutral or Park position (A/T) or depress clutch pedal (M/T). Turn ignition to START position. Ensure battery voltage exists between ground and ECU terminal A1 (Pink wire). If battery voltage is not present, repair short or open in starter relay circuit. If battery voltage is present, replace ATS ECU and retest.
