Hi drew51,
Thank you for the donation.
Problem seems to be a Body Control Module fault. Perform the following to see if any trouble codes are present.
LIGHTING SYSTEMS DIAGNOSTIC SYSTEM CHECK
Retrieve and display DTCs by entering Body Control Module (BCM) using SECURITY indicator diagnostic mode. See RETRIEVING BODY CONTROL MODULE DIAGNOSTIC TROUBLE CODES. If diagnostic mode is entered and DTCs are retrieved, go to next step. If diagnostic mode cannot be entered, perform TEST C: CANNOT ENTER BODY CONTROL MODULE DIAGNOSTICS under SYSTEM TESTS in BODY CONTROL MODULES - CAMARO & FIREBIRD article.
2. If both DTCs 12 and 55 are retrieved, go to next step. If either DTCs 12 and 55 are not retrieved, perform TEST C: CANNOT ENTER BODY CONTROL MODULE DIAGNOSTICS under SYSTEM TESTS in BODY CONTROL MODULES - CAMARO & FIREBIRD article.
3. If DTCs 21/31 or DTCs 22/32 are not retrieved, go to next step. If DTCs 21/31 or DTCs 22/32 are retrieved, perform appropriate test in accordance with DTC retrieved. See DIAGNOSTIC TROUBLE CODE DEFINITIONS in BODY CONTROL MODULES - CAMARO & FIREBIRD article.
4. If any other DTCs are retrieved, perform appropriate test in accordance with DTC retrieved. See DIAGNOSTIC TROUBLE CODE DEFINITIONS in BODY CONTROL MODULES - CAMARO & FIREBIRD article. If other DTCs are not retrieved, repair courtesy lights as necessary. See ILLUMINATION/INTERIOR LIGHTS article.
RETRIEVING BODY CONTROL MODULE DIAGNOSTIC TROUBLE CODES
CAUTION:If vehicle is equipped with THEFTLOCK(R) (radio anti-theft feature), obtain secret code from customer. Disable THEFTLOCK(R) prior to disconnecting power to vehicle or removing RADIO fuse. See RADIO ANTI-THEFT FEATURE (THEFTLOCK(R)) DISABLING under PROGRAMMING. Enable THEFTLOCK(R) after restoring power to vehicle or reinstalling RADIO fuse. See RADIO ANTI-THEFT FEATURE (THEFTLOCK(R)) UNLOCKING under PROGRAMMING.
NOTE:
Diagnostic Trouble Codes (DTC) 41-45 will only set while in Body Control Module (BCM) diagnostic mode and a button on remote transmitter is pressed. DTCs 42-45 are used to determine performance of remote transmitter and receiver in BCM.
Body Control Module (BCM) is equipped with a self-diagnostic system which detects system failures or abnormalities. When a malfunction occurs, BCM will store a numerical Diagnostic Trouble Code (DTC). DTCs are recorded as current or history/intermittent failures. A current DTC means a fault is present when diagnostic mode is entered. Current DTCs can be identified by number "2" preceding a DTC. For example, 21, 22, 24, etc.
A history DTC means a fault has occurred sometime after DTCs were last cleared from BCM memory. History/intermittent DTCs can be identified by number "3" preceding the DTC. For example, 31, 32, 34, etc. If a history/intermittent DTC is set, fault may be intermittent or system for which DTC is set may not be currently operating. Intermittent DTCs may be caused by problems with electrical circuit. If a visual inspection does not locate problem, vehicle may be driven with a DVOM attached to suspect circuit. Abnormal voltage or resistance readings when problem occurs indicates problem is within that circuit.
Using SECURITY Indicator
1. Turn ignition switch to RUN position to deactivate Content Theft Deterrent (CTD) alarm system (if equipped). Turn ignition switch to OFF position. Remove RADIO fuse No. 17 (15-amp) from instrument panel fuse block. RADIO fuse is located in lower right-hand corner of instrument panel fuse block.
2. Turn ignition switch to ACC position. Chime will sound 1-2 times to verify system has entered programming mode for customizing special features. Within 5 seconds, turn ignition switch to OFF position, then immediately back to ACC position. Chime will sound 3 times to verify diagnostic mode has now been entered. If chime does not sound 3 times, diagnostic mode has not been entered. Perform TEST C: CANNOT ENTER BODY CONTROL
MODULE DIAGNOSTICS under SYSTEM TESTS in BODY CONTROL MODULES - CAMARO & FIREBIRD article.
3. BCM will start to flash DTCs on SECURITY indicator 4 seconds after entering diagnostic mode. Each flash of indicator represents a number. For example, one flash followed by 2 quick flashes represents DTC 12. DTC 12 will always be the first DTC displayed, indicating diagnostic mode is at beginning of DTC display. Last DTC to be displayed will be DTC 55 followed by hardware configuration, then software configuration. Each DTC is displayed 3 times before next DTC is displayed.
4. If more than one DTC is present, DTCs will display beginning with lowest current DTC to highest current DTC, followed by lowest history DTC to highest history DTC. Remote transmitter DTCs 41-45 will then be displayed if invoked while in diagnostic mode. DTCs will cycle sequentially until diagnostic mode is exited. To exit diagnostic mode, turn ignition switch to OFF position, and install RADIO fuse.
