DIAGNOSIS AND TESTING
Anti-Lock Control
Diagnostic Trouble Code (DTC) Definition
The following DTCs relate to the anti-lock brake
system (ABS):
• DTC C1095 Hydraulic Pump Motor Circuit
Failure
— DTC C1095 is generated when the anti-lock
brake control module detects that the pump
motor cannot run when commanded to do so
or is running erroneously. The anti-lock brake
control module checks the pump operation at
key ON. If the brake pedal is depressed, the
test will be delayed until the brake pedal is
released. This motor test occurs each time the
vehicle is started or at the end of an ABS
event. The motor will run during ABS events
causing pedal pulsations.
• DTCs C1145, C1155, C1165, and C1175, Speed
Sensor Input Circuit Failure
— These DTCs are generated when the anti-lock
brake control module detects an open or short
to ground in the circuits to the anti-lock brake
sensor, an open or shorted sensor coil, or an
open or shorted trigger circuit in the anti-lock
brake control module.
• DTCs C1233, C1234, C1235, and C1236,
Anti-Lock Brake — Input Signal Missing
— These DTCs are generated when the anti-lock
brake control module detects a missing sensor
signal causing unwarranted ABS cycling or an
extended locked wheel behavior.
• DTC C1267 ABS Functions — Temporarily
Disabled
— DTC C1267 is generated when the anti-lock
brake control module detects an internal
failure.
Anti-Lock Control
• DTC B1342 ECU Is Defective
— DTC C1267 is generated when the anti-lock
brake control module detects an internal
failure.
• DTC B1676 Battery Voltage Out of Range
— DTC B1676 is generated when the anti-lock
brake control module detects the battery
voltage is less than 9 volts on the internal
ignition RUN signal for more than 200
milliseconds with the vehicle speed greater
than 20 km/h (12 mph) (operational) or any
speed (self-test), or battery voltage is greater
than 19 volts on the internal ignition RUN
signal for more than 0.5 milliseconds. The
DC/DC converts high-voltage to low voltage
for various low voltage systems. Less than 10
volts may be present during this test and the
DC/DC may not be on-line continuously. This
DTC can be set from a DC/DC circuit that is
failing intermittently.
The following DTCs relate to the traction inverter
module (TIM) and anti-lock brake control module
interface:
• DTC C1184 ABS System Is Not Operational
— The anti-lock brake control module has a fault
line which it uses to notify the traction
inverter module (TIM) when an anti-lock
brake system (ABS ) fault occurs. The
anti-lock brake control module outputs a 12
volt signal that it pulls low (0 volts) when it
detects an ABS fault. This signal stays low
until the concern has been corrected. The TIM
generates DTC C1184 and disables
regenerative braking during normal operation
when it detects the ABS fault line is low. If
DTC C1184 occurs, the malfunction indicator
lamp (MIL), red brake warning indicator, and
yellow ABS warning indicator are illuminated.
