Do The Following To Check That Pass Key Will Detect The Use Of An Incorrect Key:

• Shut off engine. Remove hush panel under steering column and disconnect C242 (Two-cavity connector at base of steering column).
• Connect the J35628 Interrogator between both halves of C242. Set the Key Code Selector on the J35628 Interrogator to an incorrect resistance value.
• Attempt to start engine. Theft deterrent warning message is displayed. Engine should not crank and SECURITY Indicator should stay on, indicating an incorrect key code. If engine cranks, see SYMPTOM TABLE  .
• Disconnect J35628 Interrogator. Engine should crank. Reconnect C242 and attempt to start engine again (must be done within two minutes of first attempt). If engine cranks, replace PASS Key Decoder Module.
• Turn ignition Switch to OFF. Wait four minutes and turn ignition switch to START. Engine starts normally.
• Reinstall hush panel.

See SYSTEM DIAGNOSIS  when a result is not normal.
