System Does Not Operate

NOTE: Ensure battery is fully charged and all fuses are okay.
  1. Ground Circuit Check Obtain radio security code. Disconnect battery cable terminals. Disconnect anti-theft control module 6-pin and 10-pin wiring harness connector. See ANTI-THEFT CONTROL MODULE LOCATION table. Connect ohmmeter negative lead to ground. Connect positive lead to anti-theft control module 10-pin wiring harness connector terminal No. "3" (Brown wire). If continuity is present, go to next step. If continuity is not present, repair open circuit.
  2. Power Circuit Check Connect battery cable terminals. Connect voltmeter negative lead to ground. Connect positive lead to anti-theft control module 6-pin wiring harness connector terminal No. "3" (Red wire). Switch positive lead to anti-theft control module 10-pin wiring harness connector terminal No. "1" (Red wire). If 12 volts are present at both terminals, go to next step. If 12 volts are not present, repair open circuit.
  3. Turn ignition on. Leave voltmeter negative lead connected to ground. Connect positive lead to anti-theft control module 10-pin wiring harness connector terminal No. "4" (Black wire). If 12 volts are present, go to next step. If 12 volts are not present, repair open circuit.
  4. Alarm Horn Check Turn ignition off. Connect ohmmeter negative lead to ground. Connect positive lead to anti-theft control module 6-pin wiring harness connector terminal No. "4" (Black wire). If continuity is present, go to next step. If continuity is not present, repair open circuit. If circuit is okay, replace alarm horn.
  5. Door Lock Switch Check Connect voltmeter negative lead to ground. Connect positive lead to anti-theft control module 10-pin wiring harness connector terminal No. "7" (Red/Yellow wire). Insert key in driver's door lock. Turn key to lock position and hold momentarily. Voltmeter should register 12 volts. Repeat procedure for passengers door. If voltage is correct for each door, go to next step. If voltage is not correct, repair open circuit or replace switch.
  6. Door Lock Switch Check Connect voltmeter negative lead to ground. Connect positive lead to anti-theft control module 10-pin wiring harness connector terminal No. "6" (Red/Black wire). Insert key in driver's door lock. Turn key to unlocked position and hold momentarily. Voltmeter should register 12 volts. Repeat procedure for passengers door. If voltage is correct for each door, go to next step. If voltage is not correct, repair open circuit or replace switch.
  7. Alarm Switch & Hood Check Connect ohmmeter negative lead to ground. Disconnect negative battery cable. Connect positive lead to the following anti-theft control module connector terminals:
    • 10-pin harness connector terminal No. "5" (Gray wire).
    • 10-pin harness connector terminal No. "8" (Brown/Red wire).
    • 10-pin harness connector terminal No. "9" (Brown/Green wire).
    • 10-pin harness connector terminal No. 10 (Brown/White wire).

    If continuity is present, check for circuit short to ground. If circuit is okay, replace switch. If continuity is not present, go to next step.

  8. Indicator Light Check Leave ohmmeter negative lead connected to ground. Connect negative battery cable. Using multimeter set on 10 A DC scale, connect positive lead to anti-theft control module 10-pin wiring harness connector terminal No. "2". If indicator light comes on, replace anti-theft control module. If indicator light does not come on, repair open circuit in wiring harness.
