Circuit Description
Quad Driver Modules (QDM) are used by 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 device PCM is commanding on. ODMs can diagnose each circuit individually. If ODM "C" output 2 (cruise inhibit driver circuit) detects an improper voltage level, P1662 is set.
Conditions required to set DTC are:
- Ignition is on.
- An improper voltage level has been detected on cruise inhibit driver circuit.
- Listed conditions present for greater than 30 seconds.
