P1662 PONTIAC Description
Quad Driver Modules (QDM) are used by Powertrain Control Module (PCM) to turn on current driven devices needed to control various engine and transaxle functions. Each ODM can control up to 7 outputs, including cruise inhibit driver circuit, by supplying ground to the device PCM is commanding on. ODMs can diagnose each circuit inpidually. If ODM detects an improper voltage level in output circuit controlling the stepper motor cruise control inhibit circuit, the P1662 code will set.
