4E-56 ABS AND TCS
DIAGNOSTIC TROUBLE COED (DTC) 245 - WHEEL SPEED SENSOR
Circuit Description
The toothed wheel generates a voltage pulse as it
moves past the wheel speed 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 wheel speed.
The voltage generated depends on the air gap between
the wheel speed sensor and the toothed wheel, and
on the wheel speed.
Diagnosis
This DTC will set when the EBCM cannot identify which
wheel speed sensor is causing the malfunction. It is
necessary to check all wheel speed sensors and
associated wiring to determine the cause of the DTC.
Cause
•
Incorrect number of teeth on the toothed wheel.
•
Damaged or broken teeth on the toothed wheel.
•
Open or short in speed wheel speed sensor wiring.
Action Taken When the DTC Sets
Antilock brake system (ABS) action is disabled and
the ABS warning lamp is ON.
FREQUENCY ERROR
Test Description
The number(s) below refer to Step(s) on the diagnostic
table.
1. This step begins the examination of the front wheel
speed sensor sensors.
3. This step checks for a problem with one of the
front toothed rings.
5. This step checks the front wheel speed sensors.
7. This step checks for shorts in a front wheel speed
sensor harness.
9. This step checks for opens in a front wheel speed
sensor harness.
11. This step begins a check of the rear wheel speed
sensors.
13. This step checks for a problem with one of the
rear toothed rings.
15. This step checks the rear wheel speed sensors.
17. This step checks for shorts in a rear wheel speed
sensor harness.
19. This step checks for opens in a rear wheel speed
sensor harness.
