12
Diagnostic System
Operational. This code is
always sent.
21
Right Front Wheel Speed
Sensor circuit. Checks for
open, shorted or
intermittent condition in
subject circuit. Vehicle
speed must be equal to or
greater than 4 MPH for this
code to set.
22
Right Front Toothed
Wheel Frequency Error.
Checks for excessively
dirty, or damaged toothed
wheel (sensor ring). Mis-
matched tire sizes, or use
of the temporary (mini)
spare tire may set this
code.
25
Left Front Wheel Speed
Sensor circuit. Checks for
open, shorted or
intermittent condition in
subject circuit. Vehicle
speed must be equal to or
greater than 4 MPH for this
code to set.
26
Left Front Toothed Wheel
Frequency Error. Checks
for excessively dirty, or
damaged toothed wheel
(sensor ring). Mis-matched
tire sizes, or use of the
temporary (mini) spare tire
may set this code.
31
Right Rear Wheel Speed
Sensor circuit. Checks for
open, shorted or
intermittent condition in
subject circuit. Vehicle
speed must be equal to or
greater than 4 MPH for this
code to set.
32
Right Rear Toothed
Wheel Frequency Error.
Checks for excessively
dirty, or damaged toothed
wheel (sensor ring). Mis-
matched tire sizes, or use
of the temporary (mini)
spare tire may set this
code.
35
Left Rear Wheel Speed
Sensor circuit. Checks for
open, shorted or
intermittent condition in
subject circuit. Vehicle
speed must be equal to or
greater than 4 MPH for this
code to set.
36
Left Rear Toothed Wheel
Frequency Error. Checks
for excessively dirty, or
damaged toothed wheel
(sensor ring). Mis-matched
tire sizes, or use of the
temporary (mini) spare tire
may set this code.
41
Right Front Solenoid
Valve circuit. This code
will set if the physical
position of the subject
valve does not match the
commanded position as
given by the EBCM
(Electronic Brake Control
Module).
45
Left Front Solenoid Valve
circuit. This code will set if
the physical position of the
subject valve does not
match the commanded
position as given by the
EBCM (Electronic Brake
Control Module).
55
Rear Axle Solenoid Valve
circuit. This code will set if
the physical position of the
subject valve does not
match the commanded
position as given by the
EBCM (Electronic Brake
Control Module).
61
Pump Motor or Motor
Relay circuit. This code
will set if the position of the
motor relay contacts do not
match the commanded
position of those contacts
as given by the EBCM
(Electronic Brake Control
Module). There is a motor
monitoring circuit in the
EBCM which will detect a
defective relay or pump
motor.
63
Solenoid Valve Relay
circuit. This code will set if
the position of the valve
relay contacts do not match
the commanded position of
those contacts as given by
the EBCM (Electronic
Brake Control Module).
There is a motor monitoring
circuit in the EBCM which
will detect a defective relay
or a failure in the
associated circuitry.
71
EBCM (Electronic Brake
Control Module) failure.
This code will set if there is
an internal failure of the
Electronic Brake Control
Module.
