  1. Perform PASS-KEY II(R) DIAGNOSTIC SYSTEM CHECK under SYSTEM CHECK . Ensure system will detect use of incorrect key by turning off engine.

Attempt to start engine.
  2. If engine cranks, replace PASS-Key II(R) Decoder Module and repeat PASS-KEY II(R) DIAGNOSTIC SYSTEM CHECK under SYSTEM CHECK . If engine does not crank within 3-minute lock-out period while SECURITY indicator is illuminated, turn ignition off. Disconnect interrogator and reconnect 48-pin connector at base of steering column. Attempt to start engine. If engine cranks, replace PASS-Key II(R) Decoder Module and repeat PASS-KEY II(R) DIAGNOSTIC SYSTEM CHECK under SYSTEM CHECK .
  3. If engine does not crank, turn ignition off. Wait at least 3 minutes until end of lock-out period (SECURITY indicator will go out) and attempt to start engine. If engine does not start, see NOTES ON INTERMITTENTS . If engine starts, system is functioning correctly. If an intermittent problem is suspected, see NOTES ON INTERMITTENTS.
