Test No. 13: Odometer & Twin Trip Display Does Not Alter While Driving

Test drive vehicle and check speedometer operation. If speedometer operates, go to next step. If speedometer does not operate, disconnect instrument cluster harness connector "D". Raise and support vehicle. Turn ignition on. Measure voltage between harness connector "A", terminals No. 13 (Blue/Red wire) and No. 10 (Blue/Black wire). See WIRING DIAGRAMS . Voltage should vary between zero volts and 11 volts or greater while rotating driveshaft. If voltage is as specified, replace circuit plate and retest. If voltage is not as specified, check ABS ECU. See appropriate ANTI LOCK article in BRAKES. Repair as necessary. If ABS ECU is okay, repair Blue/Red wire between ABS ECU and instrument cluster.
Remove instrument cluster. Disconnect instrument cluster harness connector "D". Using jumper wires, connect terminals No. 2 (Yellow wire), No. 13 (Blue/Red wire) and No. 23 (White/Black wire) of harness connector "D" to the respective terminals on instrument cluster. See WIRING DIAGRAMS . Raise and support vehicle. Turn ignition on. Measure voltage between harness connector "D", terminals No. 13 and 23. Voltage should vary between zero volts and 11 volts or greater while rotating driveshaft. If voltage is not as specified, replace circuit plate and retest. If voltage is as specified, replace trip meter and retest.
