1996 Ford Bronco/F-Series 4-Wheel ABS Code 25 Circuit Diagram (06-09B-35)

This is a scanned page (06-09B-35) from the 1996 Ford Body/Chassis service manual section 'Brake, Anti-Lock, 4-Wheel' covering Diagnosis and Testing for ABS trouble Code 25. The page shows the 'Affected Circuit(s)/Electrical Component(s)' diagram for Code 25, including the 4-wheel anti-lock brake hydraulic control unit connector (harness side and component side views, pins 1, 4, 5 and 8), the outlet right front dump valve (3-6 ohms), and the 4-wheel anti-lock brake electronic control module connector (harness side). Wire circuits are identified as Circuit 532 (Orange/Yellow) and Circuit 498 (Pink), with all connector views shown looking into the connector. The Description explains that Code 25 is generated by the ABS electronic control module detecting an open or shorted Circuit 498 (PK), an open or shorted outlet front right valve coil, or an open or shorted driver within the module. Possible contributing concerns listed include an intermittent open in Circuit 498 (PK), terminal backout at ECM connector Pin 15, terminal backout at hydraulic control unit connector Pins 1, 4 and 8, an open/shorted outlet front right valve coil, and an open/shorted driver in the module. The footer confirms applicability to 1996 F-150, F-250, F-350, Bronco, and F-Super Duty.
