CONDITION POSSIBLE CAUSE
C1200 Left front wheel
speed sensor circuit open or shorted •

• Vehicle: Running ABS module
detected that the
Left Front wheel
speed sensor input
signal to ABS
module is open or
shorted. •
Left Front wheel
speed sensor
• Harness is open or
shorted
• ABS module
DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn ignition switch on.
• With the scan tool, record and erase stored DTCs in the ABS module.
• Cycle the ignition switch from off to on.
• Start the engine and warm it to normal operating temperature.
• Turn ignition switch off and wait for a few seconds.
• Start the engine. With the scan tool connected to the DLC, drive the vehicle over 40 km/h (25 mph).
NOTE :
Vehicle must be driven above 40 km/h (25 mph) for fault setting conditions to be met.
• With the scan tool select: View ABS Data Stream and DTC.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 12 Brakes for more information).
• Erase all codes and test drive the vehicle to verify the repair is complete.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
Diagnostic Procedure
1.CHECK ABS MODULE DTC
• With the scan tool select: View ABS Data Stream.
• With an assistant driving the vehicle, check the following data stream list items while driving the vehicle over 40
km/h (25 mph).
Left Front Wheel Speed
Right Front Wheel Speed
Left Rear Wheel Speed
Right Rear Wheel Speed
• With the scan tool, read active DTCs in the ABS module.
Is DTC C1200 present and the Left Front Wheel Speed signal abnormal?
Ye s>>Go to the next step.
No
>>The condition that caused this DTC to set is currently not present (See Diagnostic Help and Intermit-
tent DTC Troubleshooting in Section 12 Brakes for more information).

Downloaded from www.Manualslib.com manuals search engine 5.CHECK LEFT FRONT WHEEL SPEED SENSOR GROUND CIRCUIT FOR AN OPEN
• Turn ignition switch off.
• Disconnect the ABS module electrical connector.
• For 1.6L/1.8L engine: Check the continuity between
terminal 2 of the ABS module connector E-002, and
terminal 1 of the Left Front wheel speed sensor
connector E-028, terminal side.
• For 2.0L/2.4L engine: Check the continuity between
terminal 2 of the ABS module connector A-020, and
terminal 1 of the Left Front wheel speed sensor
connector B-021, terminal side.
• Continuity should exist.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Repair or replace the circuit for an open.
6.CHECK LEFT FRONT WHEEL SPEED SENSOR GROUND CIRCUIT FOR A SHORT TO GROUND
• Check the continuity between terminal 1 of the Left Front wheel speed sensor connector, terminal side and
ground.
• Continuity should not exist.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Repair or replace the circuit for a short to ground.
7.CHECK LEFT FRONT WHEEL SPEED SENSOR GROUND CIRCUIT FOR A SHORT TO VOLTAGE
• Check the voltage between terminal 1 of the Left Front wheel speed sensor connector, terminal side and
ground.
• Voltage should not exist.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Repair or replace the circuit for a short to battery.
8.CHECK DTC
• With the X-431 scan tool, read the ABS module DTCs.
• Refer to DTC Confirmation Procedure.
Is DTC C1200 present?
Ye s>>Replace the ABS module (See ABS Module Removal & Installation in Section 12 Brakes).
No
>>The system is now operating properly.
Erase all codes and test drive the vehicle to verify the repair is complete.
