LEFT REAR WHEEL SPEED SENSOR CIRCUIT (CONTINUED)
11.
MEASURE THE RESISTANCE BETWEEN GROUND AND THE LEFT REAR WHEEL SPEED SENSOR
SIGNAL CIRCUIT
With the ignition off.
Disconnect the CAB harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance between ground and the Left Rear Wheel
Speed Sensor Signal circuit at the CAB harness connector.
Is the resistance below 100 kohms?
Yes
>> Repair the Left Rear Wheel Speed Sensor Signal circuit
for a short to ground.
Perform ABS VERIFICATION TEST.
No
>> Go to 12

MEASURE THE RESISTANCE BETWEEN THE LEFT REAR WHEEL SPEED SENSOR 12 VOLT SUPPLY
CIRCUIT AND THE SENSOR SIGNAL CIRCUIT
With the ignition off.
Measure the resistance between the Left Rear Wheel Speed Sensor
12 Volt Supply circuit and the Left Rear Wheel Speed Sensor Signal
circuit at the CAB harness connector.
Is the resistance below 100 kohms?
Yes
>> Repair the Left Rear Wheel Speed Sensor 12 Volt Supply
circuit for a short to the Left Rear Wheel Speed Sensor
Signal circuit.
Perform ABS VERIFICATION TEST.
No
>> Replace the Controller Antilock Brake. (Refer to 8 - ELEC-
TRICAL/ELECTRONIC CONTROL MODULES/CONTROL-
LER ANTILOCK BRAKE - REMOVAL).
Perform ABS VERIFICATION TEST.

VISUALLY INSPECT COMPONENTS FOR DAMAGE AND CORRECT INSTALLATION
Visually inspect the related wiring harness and connectors. Look for any chafed, pierced, pinched, or partially bro-
ken wires. Look for broken, bent, pushed out, or corroded terminals.
Visually inspect the Left Rear Wheel Speed Sensor, connector and tone wheel for damage and correct installation.
Are there any visible Sensor, connector or tone wheel concerns?
Yes
>> Correct the sensor, connector or tone wheel concerns as necessary.
Perform ABS VERIFICATION TEST.
No
>> Go to 14

MONITOR ALL WHEEL SPEED SENSORS WITH THE DRB III
T
With the DRB III
T
, erase DTCs.
Start the engine.
With an assistant to drive, use the DRB III
T
to monitor all wheel speed
sensors. Slowly accelerate as straight as possible from a stop to 24
km/h (15 MPH).
Is the Left Rear Wheel Speed Sensor Signal 0 or differing from
others by more than 5 km/h (3 MPH)?
Yes
>> Replace the Left Rear Wheel Speed Sensor. (Refer to 5 -
BRAKES/ELECTRICAL/REAR WHEEL SPEED SENSOR -
REMOVAL).
Perform ABS VERIFICATION TEST.
No
>> Inspect and repair the related wiring harness for a possible
intermittent condition.
Perform ABS VERIFICATION TEST.

RIGHT REAR WHEEL SPEED SENSOR CIRCUIT (CONTINUED)
When Monitored and Set Condition
•
When Monitored (Supply circuit): Ignition on. The Controller Antilock Brake (CAB) monitors the wheel speed
circuit every 7 milliseconds (ms).
•
When Monitored (Signal circuit): Wheel speed comparison is checked at drive off or every 7 milliseconds (ms).
Sensor Signal continuity is checked every 7 milliseconds. Wheel speed phase length supervision is checked
every 7 milliseconds.
•
Set Condition (Supply circuit): If the CAB detects an open or shorted wheel speed sensor circuit, the Diag-
nostic Trouble Code (DTC) will set.
•
Set Condition (Signal circuit): If, during an ABS stop, the CAB commands any valve solenoid on for an
extended length of time, and does not see a corresponding wheel speed change, the Diagnostic Trouble Code
(DTC) is set. The DTC can also set if the Signal is missing or erratic.
POSSIBLE CAUSES
RIGHT REAR WHEEL SPEED SENSOR 12 VOLT SUPPLY CIRCUIT SHORT TO VOLTAGE
RIGHT REAR WHEEL SPEED SENSOR 12 VOLT SUPPLY CIRCUIT SHORT TO GROUND
RIGHT REAR WHEEL SPEED SENSOR 12 VOLT SUPPLY CIRCUIT OPEN
RIGHT REAR WHEEL SPEED SENSOR SIGNAL CIRCUIT SHORT TO GROUND
RIGHT REAR WHEEL SPEED SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE
RIGHT REAR WHEEL SPEED SENSOR SIGNAL CIRCUIT OPEN
RIGHT REAR WHEEL SPEED SENSOR CIRCUITS SHORT TOGETHER
