Test E: DTCs C1233, C1234, C1235 or C1236 - Wheel Speed Sensor Input Signal Missing

Pinpoint Test E: DTCs C1233, C1234, C1235 or C1236 - Wheel Speed Sensor Input Signal Missing
Refer to Vehicle/Diagrams, Vehicle Dynamic Systems for schematic and connector information.

Normal Operation
The wheel speed sensor and sensor ring generate a signal to the ABS module that is proportional to the wheel speed. The ABS module compares the wheel speed inputs from all wheel speed sensors to determine an impending wheel lockup.





This pinpoint test is intended to diagnose the following:
^ Mismatched tire sizes
^ Wheel speed sensor ring
^ Wheel speed sensor
^ ABS module
