Cruise Control Switch Check

  1. Remove steering wheel pad. See AIR BAG RESTRAINT SYSTEM article in the ACCESSORIES/SAFETY EQUIPMENT section. Disconnect cruise control switch 6-pin connector. Use an ohmmeter to check resistance between terminals No. 3 and 4 while moving switch to the appropriate positions. See CRUISE CONTROL SWITCH RESISTANCE CHECK SPECIFICATIONS  table. See Fig 1.
    NOTE: If code 34 is displayed, carefully ensure resistance is infinite in neutral position, especially when switching between RES/ACC and SET/COAST positions.
  2. If resistance readings are correct, go to WIRING HARNESS CHECK. If resistance readings are incorrect, replace cruise control switch.
