Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Trouble Shooting: Notes
The Anti-Lock Brake System (ABS) is capable of storing Diagnostic Trouble Codes (DTCs) when a system malfunction is detected. During a malfunction, ABS warning light may flash or remain illuminated. On Passport, Rodeo and Trooper, DTCs can be retrieved by observing ABS warning light, or by using scan tool. On Hombre, a scan tool must be used to retrieve DTCs. See SELF-DIAGNOSTICS. If a DTC is not present, but a malfunction is evident, trouble shooting may be performed by symptom. See SYMPTOM DIAGNOSIS .
