 · As we’ve all ready seen, most quad driver circuit faults are due to a short in a device or its circuit. (Wiring/connectors). However at times a device or circuit that is open will set a quad driver fault code. Before replacing an ECM, always isolate the problem device or circuit. Replace the defective device or repair the circuit, and retest. Each quad driver can control up to four devices.  · 28 - Quad-driver module (computer) circuit #2 fault. 29 - Quad driver module (computer) 4th gear circuit. 31 - Camshaft position sensor fault. 32 - EGR circuit fault. 33 - Map sensor signal out of range, high. 34 - Map sensor signal out of range, low. 35 - Idle air control sensor circuit fault. 36 - Ignition system circuit error.  · When hooking up a scan-tool to my girlfriend's daughter's 93 SC2 DOHC, I get a Quad Driver Module 1 Fault.
