KS Module
The
ECM employs an internal integrated circuit to continuously monitor the knock control evaluation circuit. The KS module contains the circuitry that allows the ECM to utilize the Knock Sensor
(KS) signals and diagnose the KS sensors and circuitry. The KS module is not a replaceable component. If the ECM detects a fault in the ability of the KS module to sample these signals, a DTC will set.
