Pinpoint Test B - Alarm Does Not Disarm Properly
- Start vehicle, then turn ignition off. Disconnect Anti-Theft Control Module connectors and Remote Keyless Entry Module connector. Connect a jumper wire between Remote Keyless Entry Module connector C3, terminal No. 3 (Red/Yellow wire) and terminal No. 6 (Black wire). See Figure . Measure resistance between Anti-Theft Control Module connector C2, terminal No. 8 (Red/Orange wire) and terminal No. 26 (Black/White wire). Repeat procedure for Anti-Theft Control Module connector C1, terminal No. 7 (Pink/Orange wire) and terminal No. 26 (Black/White wire). If resistance is less than 100 ohms for both readings, go to next step. If resistance is more than 100 ohms for either readings, repair open in circuit No. 163 (Red/Orange wire) or circuit No. 118 (Pink/Orange wire) and retest system.
- Turn ignition on. Measure voltage between Anti-Theft Control Module connector C1, terminal No. 7 and terminal No. 26 (Black/White wire). If voltage is more than 9 volts, go to next step. If voltage is less than 9 volts, go to step 4)
- Check 10-amp fuse No. 5 from fuse junction panel. If fuse is bad, replace fuse and retest system. If fuse is good, repair open in circuit No. 296 (White/Purple wire) and retest system.
- Connect Remote Keyless Entry Module connector. Unlock door lock with key, leaving key rotated to unlock position. Measure resistance between Anti-Theft Control Module connector C1, terminal No. 6 (Dark Green/Purple wire) and terminal No. 26 (Black/White wire). Repeat procedure for passenger door. If both readings are more than 100 ohms, go to next step. If both readings are less than 100 ohms, go to step 6).
- Disconnect driver door lock cylinder switch. Check for continuity across door lock cylinder switch terminals while turning lock cylinder with key. Repeat procedure for passenger door lock cylinder switch. If there is continuity with key in unlock position and no continuity with key in lock position, repair open in circuit No. 25 (Dark Green/Purple wire) and retest system. If continuity is not as stated above, replace damaged door lock cylinder switch(es) and retest system.
- Connect Anti-Theft Control Module connectors. Ensure voltage at Anti-Theft Control Module connector C2, terminal No. 9 (Pink/Black wire) is less than 2 volts and that a momentary battery voltage signal is present at connector C2, terminal No. 8 (Red/Orange wire) when doors are unlocked via keyless entry unlock code or remote transmitter UNLOCK button. If voltage reading is correct, replace Anti-Theft Control Module and retest system. If voltage reading is incorrect, go to next step.
- Disconnect Anti-Theft Control Module connectors. Ensure voltage at Anti-Theft Control Module connector C2, terminal No. 9 (Pink/Black wire) is less than 2 volts and that a momentary battery voltage signal is present at connector C2, terminal No. 8 (Red/Orange wire) when doors are unlocked via keyless entry unlock code or remote transmitter UNLOCK button. If voltage reading is correct, replace Anti-Theft Control Module and retest system. If voltage reading is incorrect, problem is in Remote Keyless Entry System. See appropriate KEYLESS ENTRY SYSTEM - REMOTE article.
