Code P1352 Cadillac Description
The P1352 Cadillac diagnostic trouble code (DTC) specifically relates to the Ignition Control Module (ICM) output for cylinder 2. This code indicates that the ICM is detecting a high voltage or pulse when the cylinder 2 ground is grounded. In simpler terms, the ICM is not receiving the expected signal from cylinder 2, causing a disruption in the ignition system's operation. The ignition control module is a crucial component responsible for controlling the ignition coil's firing sequence, which in turn ignites the air-fuel mixture in the engine cylinders. When the ICM output for cylinder 2 is compromised, it can lead to misfires, rough idling, poor acceleration, and overall decreased engine performance.
