Test SC-3A - Checking Speed Control Set/Resume Switch
NOTE:
Perform TEST SC-1A before proceeding.
- Disconnect 2-pin SET/RESUME switch connector (located behind speed control SET/RESUME switch). Connect a jumper wire between 2-pin speed control SET/RESUME switch connector terminals.
- Turn ignition on. Using scan tool, read speed control switch voltage. If voltage is less than one volt, replace speed control SET/RESUME switch. Perform TEST SC-VER . If voltage is one volt or more, go to next step.
- Remove jumper wire from 2-pin speed control SET/RESUME switch connector. Using external ohmmeter, check resistance of speed control SET/RESUME switch ground circuit Black wire. If resistance is less than 5 ohms, repair open speed control switch signal circuit White wire. Perform TEST SC-VER . If resistance is 5 ohms or more, repair open ground circuit Black wire. Perform TEST SC-VER .
