Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Preliminary Inspection
To check system operation, ensure shift lever is in "P" position. 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 appropriate INTERLOCK CONTROL UNIT test under COMPONENT TESTS. If shift lever cannot be moved from "P" position, check A/T gear position switch. See appropriate ELECTRONIC CONTROLS article.
