ABS With TCS Trouble Code Charts For Warning Light Codes
DIAGNOSIS
^ Faulty ABS sensor.
^ Faulty harness connector.
^ Faulty ABS/Traction Control System (TCS) control module.
TROUBLE SYMPTOM
^ ABS does not operate.
^ TCS does not operate.
NOTE: When checking ABS sensor, carefully bend or swing connector and harness to check for improper contacts or open circuits.
