Dtc-Right Rear Wheel Speed Sensor Continuity Fault - SSANGYONG Rexton Y200 Manual

4E-54 ABS AND TCS
DIAGNOSTIC TROUBLE CODE (DTC) - RIGHT REAR WHEEL SPEED
Circuit Description
The toothed wheel generates a voltage pulse as it
moves past the sensor. Each tooth-gap-tooth series
on the wheel generates the pulses. The electronic brake
control module (EBCM) uses the frequency of these
pulses to determine the wheel speed. The voltage
generated depends on the air gap between the sensor
and the toothed wheel, and on the wheel speed.
Diagnosis
This procedure checks for a malfunctioning wheel
speed sensor, a short to ground or to voltage in the
wiring, or a contact problem in a connector.
Cause
•
The wheel speed sensor is defective or
disconnected.
•
There is a problem in the wiring.
•
There is a problem with a connector.
Action Taken When the DTC Sets
ABS action is disabled, and the ABS warning lamp is
ON.
SENSOR CONTINUITY FAULT
Test Description
The number(s) below refer to step(s) on the diagnostic
table.
1. This step begins an examination for a defective
wheel speed sensor.
6. This step tests the wiring for a short to voltage.
8. This step tests the wiring for a short to ground.
10. This step tests for an open or high resistance in
the wiring.
Diagnostic Aids
Be sure that the speed sensor wiring is properly routed
and retained. This will help to prevent false signals
due to the pickup of electrical noise.
It is very important to perform a thorough inspection
of the wiring and the connectors. Failure to inspect the
wiring and the connectors carefully and completely may
result in misdiagnosis, causing part replacement with
the reappearance of the malfunction.
