Test SC-8B - Testing CLOCKSPRING Circuit For Shorts

NOTE: For connector terminal identification, refer to CONNECTOR IDENTIFICATION  . For appropriate wiring diagram, see appropriate chassis wiring diagram in the WIRING DIAGRAMS section.
  1. Disconnect cruise control switch connector. Inspect connector and clean and repair as needed. Using DRB-II in ohmmeter mode, check mode select sense circuit resistance at terminal No. 23 (Red/Light Green wire) of PCM connector.
  2. If resistance is more than 5 ohms, replace cruise control switch. Perform TEST SC-VER  . If resistance is less than 5 ohms, disconnect clockspring connector. See Figure in TEST SC-2A. Inspect connector and clean and repair as needed.
  3. Using DRB-II, check mode select sense circuit (Red/Light Green wire) resistance at terminal No. 23 (Red/Light Green wire) of PCM connector. If resistance is more than 5 ohms, replace clockspring assembly. Perform TEST SC-VER  . If resistance is less than 5 ohms, repair short to ground in Red/Light Green wire. Perform TEST SC-VER  .
