System Diagnostics

WARNING: This page is about a different car, the 1995 Dodge Pickup and 1995 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The self-diagnostic capabilities of this system, if properly utilized, can simplify testing. Cruise control system is monitored by Powertrain Control Module (PCM).

If a problem is sensed with a monitored circuit, a Diagnostic Trouble Code (DTC) is stored in PCM. Once fault codes are known, refer to DIAGNOSTIC TROUBLE CODE (DTC) table to determine questionable circuit. Test circuits and repair or replace components as required. If problem is repaired or ceases to exist, PCM cancels that fault code after 50 ignition on/off cycles. To clear codes, refer to CLEARING DTC.

A specific fault code results from a particular system failure. It is NOT necessarily the reason for that failure. Fault code does not condemn a specific component. Fault code calls out a probable malfunction area.
