System Documentation and Troubleshooting

The 1991 Yamaha FJ1200A/DC supplementary service manual provides specialized documentation for the ABS hydraulic control and electronic management systems. This publication outlines the function of wheel sensors, sensor rotors, and the hydraulic unit, detailing the diagnostic processes necessary for identifying system faults via the provided fault code logic. Chapters examine individual sensor service, electrical component testing with pocket testers, and specific maintenance requirements for the 4CR-series chassis configurations.

Specification Highlights

Technical data within the publication includes specific ABS fault code identification and circuit testing parameters for the hydraulic unit solenoid and motor relays. Reference values for front and rear wheel sensor resistance are specified at 1.19–2.21 kΩ at 20°C (68°F). The hydraulic unit solenoid resistance is documented at less than 10 Ω. Torque values for brake caliper bolts are listed at 35 Nm (25 ft-lb) and front wheel axle bolts are specified at 59 Nm (43 ft-lb). These specifications help in understanding factory workshop documentation for Yamaha motorcycles during maintenance.
