Shift & Key Interlock Systems
NOTE:
For system testing, refer to wiring schematic when checking component wiring. See Fig 1
. To check individual components, see COMPONENT TESTING
.
- To check system operation, ensure shift lever is in Park. Turn ignition on. Depress brake pedal with accelerator pedal in idle position.
- If shift lock solenoid clicks, system is working properly. If shift lock solenoid fails to click, see INTERLOCK CONTROL UNIT under COMPONENT TESTING. If shift lever cannot be moved from Park, check for proper installation procedure of shift lock solenoid. See SHIFT LOCK SOLENOID under REMOVAL & INSTALLATION. If shift lock solenoid installation is okay, test A/T gear position switch; see A/T GEAR POSITION SWITCH .
