51
Right Rear 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
(Vehicles with
Traction Control)
Left Rear 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
EBTCM (Electronic Brake
and Traction Control
Module).
55
(Vehicles without
Traction Control)
Rear ABS 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.
67
Brakelight Switch circuit
(Vehicles with Traction
Control). This code will set
if the brakelight switch
signal is not received.
71
EBCM or EBTCM
(Electronic Brake Control
or Traction Control
Module) failure. This code
will set if there is an
internal failure of the
Electronic Brake Control
Module.
73
EBTCM (Electronic Brake
and Traction Control
Module) PWM (Pulse
Width Modulated) Signal
failure (4.6 Liter engine
only). This code will set if
there is a desired torque
level signal communication
failure between the EBTCM
(Electronic Brake and
Traction Control
Module)and the PCM
(Powertrain Control
Module).
83
Low Brake Fluid Level
(Vehicles with Traction
Control). This code will set
if the brake fluid level is
low, or there is a problem
with the brake fluid level
sensing system.
