Speedometer-Pin Point Test
Gauge reads zero, full scale, too high or low1. Refer to Antilock Brake System (ABS)/Traction Control for fault diagnosis of wheel speed sensor.
2. Check harness wiring and connection from Instrument pack pin 15 (24-way connector) and ABS/Traction Control Control Module (ABS/TC CM).
3. If all previous checks prove correct remove and open the instrument pack. Examine flexi-circuit connections to speedometer, ensuring correct and secure figment.
4. Check continuity of flexi-circuit tracks to speedometer connections.
5. Check continuity of speedometer driver windings by disconnecting from flexi-circuit and testing between the upper central connection pin and each of the other two pins. If open circuit is recorded renew speedometer.
