Pinpoint Test SK, Speed Control Indicator In Instrument Cluster Does Not Come On
- Checking Speed Control Amplifier: Ensure vehicle is equipped with a Brown speed control amplifier. Speed control amplifier is located behind right side of instrument panel, near glove box, and contains a 6-pin and an 8-pin connector.
- If Brown speed control amplifier is used, proceed to step 3). If Brown speed control amplifier is not used, install correct amplifier, and recheck operation.
- Checking Voltage At Speed Control Amplifier: Disconnect 6-pin and 8-pin connectors from speed control amplifier. Turn ignition on. Connect positive lead of voltmeter to Orange/Light Blue wire of 8-pin connector and negative lead to Black wire of 6-pin connector.
- If voltage reads approximately 5 volts, proceed to step 7). If no voltage exists, proceed to step 5).
- Checking Wiring Circuit: Using ohmmeter, check continuity of Orange/Light Blue wire of 8-pin connector and instrument cluster connector C2-2, pin No. 25. See Figure .
- If continuity exists, proceed to step 7). If no continuity exists, repair open circuit in wiring.
- Performing Display Test: Turn ignition on. Connect jumper wire between Orange/Light Blue wire of 8-pin connector and Black wire in 6-pin connector, and note indicator operation.
- If indicator comes on, replace speed control amplifier. If indicator does not come on, proceed to step 9).
- Turn ignition on. Connect jumper wire between instrument cluster connector C2-2, pin No. 26 (Orange/Light Blue wire) and ground, and note indicator operation. See Figure .
- If indicator does not come on, replace instrument cluster. Install door pillar sticker to indicate instrument cluster has been replaced. If indicator comes on, check continuity of Orange/Light Blue wire of 8-pin connector and instrument cluster connector C2-2, pin No. 26. Repair wiring as necessary.
