RWAL Fault codes
Codes for Dodge RWAL, Ford RABS and GM RWAL
applications are similar but have a few differences:
- Should not occur (replace the controller if it does)
- Open isolation valve circuit or defective ABS module
- Open dump valve circuit or defective ABS module
- Grounded or closed RABS or RWAL valve switch
- Excessive actuations of dump valve during ABS
braking
- Erratic speed sensor signal
- Shorted isolation valve or defective ABS module
- Shorter dump valve or defective ABS module
- High resistance or open speed sensor circuit (resistance
should be 1000 to 2500 ohms)
- Low speed sensor resistance (Dodge & Ford only)
- Open speed sensor circuit (GM only)
- Stop lamp switch circuit (Dodge & Ford)
- ABS module speed processor (Dodge & Ford only)
- ABS module program (Dodge & Ford only)
- ABS module RAM memory failure (Dodge & Ford)
To manually clear a stored fault code on GM
and some Dodge trucks with RWAL, remove the ABS fuse or disconnect the battery
for 5 seconds. Ford RABS codes will automatically clear when the ignition is
turned to the off position.
