Chime Sounds With Driver Door Open Key Removed

Possible Causes:

• Key-In SW Status
• Key-In Ignition Shorted
• Key-In Ignition SW Sense Short To Ground
• Body Control Module

Testing

1. Ensure all exterior lights are off. With the scan tool select: BODY COMPUTER, Input Output. Read the Key-In Ignition SW. Remove the key from the ignition switch. If the scan tool shows Key-In IGN OPEN, replace the BCM. See BODY CONTROL MODULE  under REMOVAL & INSTALLATION. If the scan tool does not show Key-In IGN OPEN, go to next step.
2. Disconnect the ignition switch connector. If the chime turned off, check the ignition lock cylinder for damage. If OK, replace the ignition switch. See IGNITION SWITCH  under REMOVAL & INSTALLATION. If not OK, go to next step.
3. Turn ignition off. Disconnect the BCM C2 connector. Using a DVOM, measure the resistance of the key-in ignition switch sense circuit to ground at the ignition switch connector. If the resistance is below 100 ohms, repair the key-in ignition switch sense wire for a short to ground. If the resistance is 100 ohms or more, go to next step.
4. If there are no possible causes remaining, replace the BCM. See BODY CONTROL MODULE  under REMOVAL & INSTALLATION.
