GMC P1362 Code Description
The GMC diagnostic code P1362 refers to a low input in the ignition control module (ICM) bypass circuit. The ignition control module is a crucial component of the vehicle’s ignition system, responsible for controlling ignition timing and the firing sequence of the spark plugs. When the engine control module (ECM) detects a low input signal from the ICM bypass circuit, it triggers the P1362 code.
