VSS No. 1 Circuit (Speedometer Does Not Operate)
- If odometer does not operate, go to next step. If odometer operates, check trip meter operation. If trip meter does not operate, go to step 4). If trip meter operates, replace speedometer.
- Remove instrument cluster, but leave electrical connectors attached. Raise and support vehicle with rear wheels off of ground. Turn ignition on. At instrument cluster middle connector, connect voltmeter between terminals No. 13 (Blue/Red wire) and 15 (Red wire). Rotate drive shaft.
- If voltage alternates between zero and 11 or more volts for each revolution of drive shaft, replace printed circuit. If voltage does not alternate between zero and 11 or more volts, check VSS No. 1. See VEHICLE SPEED SENSOR (VSS) NO . 1. If VSS No. 1 is okay, repair circuit between VSS No. 1 and instrument cluster.
- Remove instrument cluster, leaving all connectors attached except middle connector. At middle connector (harness side), connect one end of a jumper wire to terminal No. 1 (Yellow wire). Connect other end of jumper wire to corresponding terminal on instrument cluster. Use same procedure for the following terminals. This simulates an attached middle connector, but with only 4 wires connected.
- No. 13 (Blue/Red wire)
- No. 15 (Red wire)
- No. 23 (White/Black wire).
- Raise and support vehicle with rear wheels off of ground. Turn ignition on. Connect voltmeter between terminals No. 13 and 15 of middle connector. Rotate drive shaft. If voltage alternates between zero and 11 or more volts for each revolution of drive shaft, replace speedometer. If voltage does not alternate between zero and 11 or more volts, replace printed circuit.
