System Operation Check

Confirm the following system operation:

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