Intermittent Diagnostic Trouble Codes

INTERMITTENT DIAGNOSTIC TROUBLE CODES
If the malfunction is not present while performing a test procedure, the diagnostic procedures will not locate the problem. In this case, the code can only suggest an area to inspect. Check for the following:
- mechanical interference with brake or accelerator pedal
- loose or corroded conditions
- damaged components (sensors, tone wheels, pedal drive cable)
- damaged wiring
- excessive axle shaft runout
- loose pedal mounting
- hydraulic system leaks
- regular brake system problems, non-ABS related If no obvious problems are found, erase diagnostic trouble codes and with the key on, wiggle the wire harness and connectors. Recheck for codes periodically as you work through the system. This procedure may uncover a difficult to locate malfunction.
