B11DB:02, B11DB:08, B11DB:11, B11DB:9A, And U1007:31

NOTE: Make sure battery voltage is greater than 12.2 volts prior to and during this pinpoint test.

NOTE: Do not have a battery charger attached during vehicle testing.

F1 CHECK ELECTRICAL CONNECTOR CONDITION
- Disconnect Battery Monitoring Sensor C1689 .
- Check the Battery Monitoring Sensor electrical connections for security, damage and corrosion.
- Check the battery cable connections.
- Connect Battery Monitoring Sensor C1689 .
Are all connectors clean and connected properly?
- Yes : GO to F2
- No : REPAIR any corrosion in the battery cable connections.
  REPAIR any damaged, bent or pushed-out pins.
F2 RETRIEVE BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition ON.
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs) in all modules.
- Using a diagnostic scan tool, perform the BCM self-test.
Did the DTC return?
- Yes : GO to F3
- No : For any PCM or BCM Diagnostic Trouble Codes (DTCs) refer to DTC CHARTS . The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.

F3 CHECK THE BATTERY MONITORING SENSOR VOLTAGE

Ignition OFF.
Disconnect Battery Monitoring Sensor C1689 .

Measure and record:

Positive Lead	Measurement/Action	Negative Lead

Measure:

Positive Lead	Measurement/Action	Negative Lead
C1689-2		Ground

Is the voltage within 0.5 volt of the recorded battery voltage?

Yes : GO to F4
No : REPAIR the circuit.

F4 CHECK THE BATTERY MONITORING SENSOR LIN CIRCUIT FOR A SHORT TO VOLTAGE

Disconnect BCM C2280C .
Ignition ON.

Measure:

Positive Lead	Measurement/Action	Negative Lead
C1689-1		Ground

Is any voltage present?

Yes : REPAIR the circuit.
No : GO to F5

F5 CHECK THE BATTERY MONITORING SENSOR LIN CIRCUIT FOR A SHORT TO GROUND

Ignition OFF.

Measure:

Positive Lead	Measurement/Action	Negative Lead
C1689-1		Ground

Is the resistance greater than 10, 000 ohms?

Yes : GO to F6
No : REPAIR the circuit.

F6 CHECK THE BATTERY MONITORING SENSOR LIN CIRCUIT FOR AN OPEN

Measure:

Positive Lead	Measurement/Action	Negative Lead
C1689-1		C2280C-4

Is the resistance less than 3 ohms?

Yes : INSTALL a new Battery monitoring sensor.
REFER to: BATTERY MONITORING SENSOR .
No : REPAIR the circuit. GO to F7

F7 CLEAR DIAGNOSTIC TROUBLE CODES (DTCS)
- Connect Battery Monitoring Sensor C1689 .
- Connect BCM C2280C .
- Ignition ON.
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs) in all modules.
- Enter the following diagnostic mode: BCM self-test.
Is DTC B11DB:02, B11DB:08, B11DB:11, B11DB:49, or B11DB:9A present?
- Yes : GO to F8
- No : For all other BCM Diagnostic Trouble Codes (DTCs) refer to DTC CHARTS .
F8 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all BCM 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 BCM 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 Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new BCM .
  REFER to: BODY CONTROL MODULE (BCM) .
  
  CLEAR all Diagnostic Trouble Codes (DTCs) in all modules.
- 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.
