Neutral Start Switch Circuit Disengagement (Response Code 223)
- Turn ignition off. Remove cruise control unit from underhood fuse and relay center. See Figure . Connect ohmmeter between ground and cruise control unit base terminal 3T. With transmission shift lever in Park or Neutral, ohmmeter should indicate zero ohms resistance. With transmission shift lever in any other position, ohmmeter should indicate infinite resistance.
- If resistances are to specification, replace cruise control unit. If resistances are not to specification, check wiring between cruise control unit base terminal 3T and starter, including neutral start switch.
