- Charging system concern
- Driver status monitor camera module (CMR)
- NOTE: This DTC may be stored in the module memory due to previous battery charging or vehicle jump starting events.
- P1 CHECK FOR OVERCHARGING DIAGNOSTIC TROUBLE CODES (DTCS) SET IN OTHER MODULES
- Ignition ON.
- Connect the diagnostic tool.
- Using a diagnostic scan tool, retrieve all Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Are any charging system DTCs recorded?
Yes DIAGNOSE the charging system concern. Refer to the appropriate Battery and Charging article for the procedure. No GO to P2 - P2 CHECK THE BATTERY VOLTAGE
- Turn off all interior/exterior lights and accessories.
- Start and run the engine at approximately 2, 000 rpm for three minutes while monitoring the battery voltage.
Positive Lead Measurement / Action Negative Lead
Does the battery voltage rise to 16 volts or higher?
Yes DIAGNOSE the charging system concern. Refer to the appropriate Battery and Charging article for the procedure. No GO to P3 - P3 RECHECK THE DRIVER STATUS MONITOR CAMERA MODULE CMDTCS
- Using a diagnostic scan tool, clear the DTCs.
- Wait 10 seconds.
- Using a diagnostic scan tool, check the CMR CMDTCs.
Is DTC U3003:17 present?
Yes GO to P4 No The system is operating correctly at this time. The DTC may have been caused by module connections or may have been set previously during battery charging or while jump starting the vehicle. ADDRESS the root cause of any connector or pin issues. - P4 CHECK FOR CORRECT DRIVER STATUS MONITOR CAMERA MODULE OPERATION
- Ignition OFF.
- Disconnect and inspect the driver status monitor camera module connectors.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the driver status monitor camera module connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new driver status monitor camera module. REFER to: Driver Status Monitor Camera Module [CMR] . No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
