ABS With TCS Trouble Code Charts For Warning Light Codes

OVERVIEW
Faulty outlet solenoid valve circuit(s) in hydraulic unit are indicated.

DIAGNOSIS
^ Faulty harness/connector.
^ Faulty solenoid valve in hydraulic unit.
^ Faulty ABS/Traction Control System (TCS) control module.

TROUBLE SYMPTOMS
^ ABS does not operate.
^ TCS does not operate.
^ ABS sequence control does not operate.
^ TCS sequence control does not operate.

PROCEDURE
1. Check resistance of solenoid valve.
a) Turn ignition switch OFF.
b) Disconnect connector from hydraulic unit.





c) Measure resistance between hydraulic unit terminals.
