Pinpoint Test A - Alarm Does Not Arm Properly

  1. Start vehicle, then turn ignition off. Disconnect Anti-Theft Control Module connectors. With doors closed, measure voltage at Anti-Theft Control Module connector C2, terminal No. 14. See Figure . If voltage is less than 9 volts, go to step 3). If voltage is more than 9 volts, go to next step.
  2. Disconnect both courtesy lamp switches. Measure voltage at Anti-Theft Control Module connector C2, terminal No. 14. If voltage is less than 9 volts, check door courtesy switches and retest system. If voltage is more than 9 volts, repair short to battery power in circuit No. 24 (Dark Blue/Orange wire) and retest system.
  3. Disconnect Anti-Theft Control Module connectors. Measure resistance between connector C1, terminal No. 6 (Dark Green/Purple wire) and connector C2, terminal No. 26 (Black/White wire). If resistance is less than 100 ohms, go to next step. If resistance is more than 100 ohms, go to step 6).
  4. Disconnect driver and passenger door lock cylinder switches. Measure resistance between connector C1, terminal No. 6 (Dark Green/Purple wire) and connector C2, terminal No. 26 (Black/White wire). If resistance is less than 100 ohms, repair short to ground in circuit No. 25 (Dark Green/Purple wire) and retest system. If resistance is more than 100 ohms, go to next step.
  5. Measure resistance across driver door lock cylinder switch terminals, repeat for passenger side. If resistance is less than 100 ohms, replace door lock cylinder switch and retest. If resistance is more than 100 ohms, go to next step.
  6. Disconnect Anti-Theft Control Module connectors and Remote Keyless Entry Module connector. Turn ignition off. Measure voltage to ground (terminal No. 26, Black/White wire) between Anti-Theft Control Module connector C2, terminal No. 8 (Red/Orange wire), connector C1, terminal No. 7 (Pink/Orange wire), connector C2, terminal No. 9 (Pink/Black wire) connector C1, terminal No. 4 (White/Purple wire). If any or all voltages are more than 2 volts, repair short to battery power in circuit No. 117 (Pink/Black wire), No. 118 (Pink/Orange wire), No. 163 (Red/Orange wire) and/or No. 296 (White/Purple wire) and retest system. If all voltages are less than 2 volts, go to next step.
  7. Turn Ignition off. Connect jumper wires between Remote Keyless Entry Module connector C3 terminal No. 16, No. 3, No. 6 and ground. See KEYLESS ENTRY SYSTEM - REMOTE article. Measure resistance between Anti-Theft Control Module connector C2, terminal No. 9 (Pink/Black wire) and terminal No. 26 (Green Yellow/Red wire). Repeat procedure between Anti-Theft Control Module connector C1, terminal No. 7 (Pink/Orange wire) and connector C2. terminal No. 8 (Red/Orange wire). If resistance is more than 100 ohms on any terminal, repair open on circuit No. 117 (Pink/Black wire), No. 118 (Pink/Orange wire) and/or No. 163 (Red/Orange wire) and retest system. If all readings are more than 100 ohms, go to next step.
  8. Measure resistance to ground (terminal No. 26, Green Yellow/Red wire) between Anti-Theft Control Module connector C1, terminal No. 7 (Pink/Orange wire) connector C2, terminal No. 8 (Red/Orange wire) and connector C2. terminal No. 9 (Pink/Black wire). If resistance is less than 100 ohms, repair short to ground in circuit No. 117 (Pink/Black wire), No. 118 (Pink/Orange wire) and/or No. 163 (Red/Orange wire) and retest system. If all readings are more than 100 ohms, go to next step.
  9. Measure voltage at Anti-Theft Control Module connector C1, terminal No. 7 (Pink/Orange wire) and connector C2, terminal No. 26 (Green Yellow/Red wire). If voltage reading is more than 9 volts, go to step 11). If reading is less than 9 volts, go to next step.
  10. Check 20-amp inline fuse (from fuse junction panel). If fuse is blown, replace fuse and retest system. If fuse is good, repair open circuit No. 196 (Dark Blue/Orange wire) and test system.
  11. Reconnect Anti-Theft Control Module connectors and Remote Keyless Entry Module connector. Ensure voltage at Anti-Theft Control Module connector C1, terminal No. 7 (Pink/Orange wire) is less than 2 volts and that a momentary battery voltage signal is present at connector C2, terminal No. 9 (Pink/Black wire) when doors are locked via keyless entry lock code (7/8 and 9/0) or remote transmitter LOCK button. If voltage reading is correct, replace Anti-Theft Control Module and retest system. If voltage reading is not correct, go to next step.
  12. Disconnect Anti-Theft Control Module connectors. Ensure voltage at Anti-Theft Control Module connector C1, terminal No. 7 (Pink/Orange wire) is less than 2 volts and that a momentary battery voltage signal is present at connector C2, terminal No. 9 (Pink/Black wire) when doors are locked via keyless entry lock code (7/8 and 9/0) or remote transmitter LOCK button. If voltage reading is correct, replace Anti-Theft Alarm Control Module and retest system. If voltage reading is not correct, check for malfunction in Keyless Entry System or remote transmitter. See KEYLESS ENTRY SYSTEM - REMOTE article.
