Key In Ignition & Driver's Door Open Chime Inoperative

WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.

Possible Causes:

Testing

  1. The driver's door ajar switch must be operational. Ensure key is in the ignition switch. With the scan tool, enter: BODY COMPUTER, Inputs Outputs and read the Key-In IGN SW. If the scan tool displays KEY-IN IGN SW: CLOSED, replace the BCM. See BODY CONTROL MODULE  under REMOVAL & INSTALLATION. If the scan tool does not display KEY-IN IGN SW: CLOSED, go to next step.
  2. Turn ignition off. Disconnect the ignition switch harness connector. Turn all lights off. Using a DVOM, measure the resistance between ground and the ground circuit in the ignition switch harness connector. If the resistance is below 5 ohms, go to next step. If the resistance is 5 ohms or more, repair the ground circuit for an open.
  3. Connect the ignition switch connector if disconnected. Turn the ignition on. With the ignition switch connector connected, backprobe key-in ignition switch sense circuit to ground at the ignition switch connector. With the scan tool, enter BODY COMPUTER Inputs/Outputs and observe the Key-In IGN SW status. If the scan tool displays KEY-IN IGN SW: CLOSED, replace the ignition switch. See IGNITION SWITCH  under REMOVAL & INSTALLATION. If not, go to next step.
  4. Turn ignition off. Disconnect the ignition switch harness connector. Disconnect the BCM C2 harness connector. Using a DVOM, measure the resistance of the key-in ignition switch sense circuit between the ignition switch connector and the BCM C2 connector. If the resistance is below 5 ohms, go to next step. If the resistance is 5 ohms or more, repair the key-in ignition switch sense circuit for an open.
  5. If there are no possible causes remaining, replace the BCM. See BODY CONTROL MODULE  under REMOVAL & INSTALLATION.
