ABS Code Meanings: Kelsey-Hayes RWAL
IMPORTANT: Always follow vehicle service manual procedures for any ABS
repairs! (Manual listings on page 4.)
1
ECM (Electronic Control
Module) Failure. This
code indicates an anti-lock
brake system control
module failure, or a mis-
read code.
2
Open Isolation valve or
defective ECM
(Electronic Control
Module). This code
indicates an open circuit in
the isolation valve or
associated wiring. The
anti-lock brake system
control module may also
have failed.
3
Open Dump valve or
defective ECM
(Electronic Control
Module). This code
indicates an open circuit in
the dump valve or
associated wiring. The
anti-lock brake system
control module may also
have failed.
4
Grounded anti-lock valve
Reset Switch. This code
indicates a grounded
circuit in the anti-lock valve
reset switch or associated
wiring
5
Excessive actuation of
the Dump valve during
an anti-lock stop. On 2
wheel drive vehicles, this
code indicates probable
failure of the isolation/
dump valve assembly. On
4 wheel drive vehicles, this
code indicates either
possible failure of the
isolation/dump valve
assembly, or a failure in
the front axle transfer case
switch or its associated
wiring and/or connectors.
6
Erratic Vehicle Speed
Sensor signal. This code
indicates either a defective
or erratic vehicle speed
sensor (check for engine
diagnostic trouble code
24), defective DRAC
(Digital Ratio Adapter
Controller) or its circuitry,
or any associated wiring.
An open battery feed fuse
to the ABS electronic
control module could also
cause this code to set.
7
Shorted Isolation valve
or defective ECM
(Electronic Control
Module). This code
indicates a shorted circuit
in the isolation valve or
associated wiring. The
anti-lock brake system
control module may also
have failed.
8
Shorted Dump valve or
defective ECM
(Electronic Control
Module). This code
indicates a shorted circuit
in the dump valve or
associated wiring. The
anti-lock brake system
control module may also
have failed.
9
Open circuit to the
Vehicle Speed Sensor
signal. This code indicates
a defective vehicle speed
sensor (check for engine
diagnostic trouble code
24), defective DRAC
(Digital Ratio Adapter
Controller) or its circuitry,
or any of its associated
wiring. An open battery
feed fuse to the ABS
electronic control module
could also cause this code
to set.
10
Stop (Brake) Light circuit.
This code indicates a
missing stop light signal
from the stop light switch.
The stop light switch may
be mis-adjusted or
defective, or there may be
a problem with its
associated wiring.
11
ECM (Electronic Control
Module) Failure. This
code indicates an anti-lock
brake system control
module failure, or a mis-
read code.
12
ECM (Electronic Control
Module) Failure. This
code indicates an anti-lock
brake system control
module failure, or a mis-
read code.
13
ECM (Electronic Control
Module) Failure. This
code indicates an anti-lock
brake system control
module failure.
14
ECM (Electronic Control
Module) Failure. This
code indicates an anti-lock
brake system control
module failure.
15
ECM (Electronic Control
Module) Failure. This
code indicates an anti-lock
brake system control
module failure.
