System Operation Check

Confirm the following system operation:

• With ignition switch in LOCK position, gearshift lever should be locked in Park.
• With gearshift lever in Park, ignition switch should be allowed movement from LOCK position to any other position, and then back to LOCK position. Ignition key should be removable while in LOCK position.
• With ignition switch in ON position, gearshift lever should be allowed movement from Park. Models equipped with BTSI solenoid require brake pedal be depressed for this operation.
• With ignition switch in ON position and gearshift lever in any position other than Park, ignition key is non-removable. Ignition key is removable only when gearshift lever is returned to Park.

If shift interlock system operates as specified, system is functioning properly at this time. If system does not operate as specified, diagnose by symptom. See SYMPTOM TESTS  .
