Pinpoint Test G - System Triggers Falsely

With hood closed, arm alarm system. Verify that system does not trigger (sound alarm) immediately after arming. If system arms and does not trigger, go to step 3). If system triggers, go to next step.
Arm alarm system. Open trunk lid and apply movement to trunk lid lock switch connector and cable. If system triggers, go to next step. If system does not trigger, disarm system. Replace trunk lid lock cylinder and glove box cylinder. Retest system.
Using a voltmeter, check voltage at anti-theft control module pin No. 3 with all doors closed. See Figure . If voltage is more than 2 volts, go to next step. If voltage is less than 2 volts, repair Black/Orange wire or door ajar switches.
Using a voltmeter, measure voltage at anti-theft control module pin No. 5. See Figure . If voltage is more than 2 volts, go to step 6). If voltage is less than 2 volts, go to next step.
Disconnect anti-theft trunk lid lock cylinder switch from wiring harness. Measure voltage at pin No. 5 of harness connector. If voltage is less than 2 volts, repair White/Purple wire between trunk switch and anti-theft control module. If voltage is more than 2 volts, replace trunk lock switch.
On models with remote keyless entry system, when alarm activates falsely, turn ignition key to RUN/ACC position. If alarm continues to sound, replace anti-theft control module and retest system. If alarm shuts off, anti-theft system is okay. Problem is in keyless entry system. See KEYLESS ENTRY SYSTEM article in the ACCESSORIES/SAFETY EQUIPMENT section.
