DTC 31: Right Front Wheel Speed Sensor Circuit: Notes

CAUTION: If Anti-Lock Brake System/Traction Control Electronic Control Unit (ABS/TRAC ECU) replacement is necessary during testing, always ensure ABS/TRAC ECU connectors and ground circuit are okay. If either is suspect, repair and repeat testing to confirm ABS/TRAC ECU malfunction.

NOTE: After each repair procedure has been completed, reconnect all components. Verify speed sensor signal. See SPEED SENSOR SIGNAL CHECK under DIAGNOSIS & TESTING.
