Diagnostic Mode

Chrysler does not provide any trouble code number-driven diagnostics for this system. Alldata users have reported success matching the code description retreived from an atermarket scan tool and matching the description to the diagnostic test information provided.

To enter diagnostic mode, a vehicle speed must be below 10 km/h (6 mph) and no ABS condition present. If vehicle speed is not below 10 km/h (6 mph), a "No Response" message could be displayed by the DRB III. The following are characteristics of diagnostic mode:

- The amber ABS warning indicator will blink rapidly (about 1/2 second ON and 1/2 second OFF). If a hard trouble code, such as CAB Power Feed Circuit Failure code is present, the indicator will be illuminated without blinking until the trouble condition is cleared.
- Antilock operation is disabled.
- You will be unable to actuate the valves in the valve body when the vehicle speed is above 8 km/h (5 mph). If valve actuation is attempted above 8 km/h (5 mph), a "No Response" message will be displayed on the DRB III.
