Anti-Theft Systems: Testing

Before performing any tests on anti-theft system, check the following items to eliminate common problems:

• Hood/trunk/liftgate properly aligned.
• Door locks not binding.
• Fuses not blown.
• Loose or corroded connections.
• Damaged wiring harness.
• Damaged anti-theft control module.
• Horn, headlights, hazard flashers, interior lights, trunk lights, power door locks and remote entry system operation.

If concern is still present after inspection, identify symptom(s) and perform appropriate pinpoint test. See the PINPOINT TEST DIRECTORY  table.
