What does ABS Code 63 mean on a 1996 Ford Bronco or F-Series?

Code 63 means the pump motor was triggered but did not run. Possible sources include a damaged pump motor, terminal backout in the anti-lock brake electronic control module harness connector Pins 17, 29, 37 and 38, an open or shorted pump motor relay coil, open contacts in the pump motor relay, or terminal backout in the pump motor 4-way connector Pins 1, 2, 3 or 4. The chart directs you to Pinpoint Test S.

What causes ABS Code 65 (Acceleration Sensor)?

Possible sources are terminal backout in the ABS electronic control module wiring harness connector Pins 30, 31 and 32; a worn or damaged acceleration switch; a worn or damaged anti-lock brake electronic control module; acceleration switch terminal backout at Pins 1, 2 and 3; or a short to ground in Circuits 836 (O/W), 886 (O/BK) and 887 (Y). Go to Pinpoint Test T.

Why is the amber ABS warning lamp on with no diagnostic code?

Possible sources include a worn or damaged ignition switch, an open ignition feed circuit to the anti-lock brake electronic control module, low battery voltage (less than 8V), a blown ignition fuse, or an open system ground. The manual directs you to Pinpoint Test V.

What should I check if both the ABS and speedometer are not working properly?

The chart lists no signal to the anti-lock brake electronic control module from the vehicle speed sensor, or a defective vehicle speed sensor, and directs you to Pinpoint Test Y.

What do ABS Codes 52 and 53 indicate?

Code 52 is a hydraulically inoperative right front outlet valve or sensor disturbance detected (go to Pinpoint Test Q); Code 53 is the same condition for the rear axle outlet valve (go to Pinpoint Test R). Possible sources include a pinched or closed brake line or hose, or a worn or clogged outlet valve.

This is page 06-09B-19 from the 1996 Ford F-150, F-250, F-350, Bronco, and F-Super Duty Body/Chassis service manual (dated July 1995), covering Diagnosis and Testing of the 4-Wheel Anti-Lock Brake (ABS) system. It presents a continued symptom/diagnostic chart with three columns: Condition, Possible Source, and Action. Conditions covered include Code 52 (hydraulically inoperative right front outlet valve or sensor disturbance), Code 53 (rear axle outlet valve), Code 63 (pump motor triggered but did not run), Code 65 (acceleration sensor), Code 67 (pump motor running but not triggered), amber ABS warning lamp on with no code, intermittent diagnosis, unknown trouble code, and ABS/speedometer not functioning properly. Each condition lists possible causes such as pinched brake lines, worn outlet valves, terminal backout at specific connector pins (e.g., pins 17, 29, 37, 38 for Code 63; pins 30, 31, 32 for Code 65), relay faults, shorts to ground in circuits 836 (O/W), 886 (O/BK), 887 (Y), and 539 (PK/LB), low battery voltage, blown ignition fuse, and defective vehicle speed sensor. Each row directs the technician to a specific Pinpoint Test (Q through Y) for further diagnosis.
