Transmission Range Switch Circuit Check (A/T)
NOTE:
Transmission range switch may also be referred to as park/neutral position switch or shift switch.
- Ensure ignition is off. Disconnect Cruise Control Electronic Control Unit (CC ECU) harness connector. Check continuity between ground and CC ECU harness connector terminal No. 9 (Black/Red wire). See Figure . With shift lever in Park or Neutral, continuity should exist. With shift lever in any other position, continuity should not exist.
- If continuity is as specified, circuit is okay. If continuity is not as specified, check wiring and harness connectors. See WIRING DIAGRAMS . Repair wiring or harness connectors as necessary. If wiring and harness connectors are okay, replace or adjust transmission range switch as necessary. See TRANSMISSION RANGE SWITCH ADJUSTMENT (A/T) under ADJUSTMENTS.
