Test E: DTCs C1296, C1297, C1298 and C1299 - Wheel Speed Sensor Signal Fault
Test E: DTCs C1296, C1297, C1298 and C1299 - Wheel Speed Sensor Signal FaultRefer to Vehicle/Diagrams, Vehicle Dynamic Systems for schematic and connector information.
Normal Operation
The wheel speed sensor and sensor ring generates a square wave signal to the anti-lock brake system (ABS) module that is proportional to the wheel speed. The ABS module compares the wheel speed inputs from all the wheel speed sensors to determine an impending wheel lockup. Incorrect tire size can set these DTCs as well.
Possible Causes
^ ABS module
^ Wheel speed sensor ring
^ Wheel speed sensor
CAUTION: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.
