PINPOINT TEST V : U1000:00

Normal Operation and Fault Conditions

The BCM uses solid state drivers (Field Effect Transistors (FET)) to control the output of several vehicle systems. When an overload occurs on any of these drivers, the BCM disables the output and tracks the number of repetitive faults on each of these circuits. The module compares this number of overloads to three progressive thresholds established for each circuit. At each threshold, DTC U1000:00 sets along with the DTC associated with the affected circuit. REFER to: Module Controlled Functions - Overview (419-10 Multifunction Electronic Modules, Description and Operation).

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
BCM B11D9:17 Vehicle Battery: Circuit Voltage Above Threshold A continuous and on-demand DTC that sets in the BCM if the BCM detects higher than expected battery voltage on the voltage supply input circuit.
BCM U3006:17 Control Module Input Power "A" Circuit/Open: Circuit Voltage Above Threshold A continuous and on-demand DTC that sets in the BCM if the BCM detects higher than expected battery voltage on the voltage supply input circuit.
BCM U3006:1C Control Module Input Power "A" Circuit/Open: Circuit Voltage Out Of Range A continuous and on-demand DTC that sets in the BCM if the BCM detects out of range voltage on the voltage supply input circuit.
BCM U3007:17 Control Module Input Power "B" Circuit/Open: Circuit Voltage Above Threshold A continuous DTC that sets in the BCM if the BCM detects higher than expected battery voltage on the voltage supply input circuit.
BCM U3013:17 Control Module Input Power "C" Circuit/Open: Circuit Voltage Above Threshold A continuous DTC that sets in the BCM if the BCM detects higher than expected battery voltage on the voltage supply input circuit.
BCM U3014:17 Control Module Input Power "D" Circuit/Open: Circuit Voltage Above Threshold A continuous DTC that sets in the BCM if the BCM detects higher than expected battery voltage on the voltage supply input circuit.

Possible Sources

  • Charging system concern
  • BCM
Z1 CHECK FOR OVERCHARGING DIAGNOSTIC TROUBLE CODES (DTCS) SET IN OTHER MODULES
  • Ignition ON.
  • Using a diagnostic scan tool, retrieve all Diagnostic Trouble Codes (DTCs).

Are any charging system Diagnostic Trouble Codes (DTCs) recorded?
Yes DIAGNOSE the charging system concern.
REFER to: Charging System (414-00 Charging System - General Information, Diagnosis and Testing).
No GO to Z2

Z2 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 over-charging system concern.
REFER to: Charging System (414-00 Charging System - General Information, Diagnosis and Testing).
No GO to Z3

Z3 RECHECK THE BCM (BODY CONTROL MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)
  • Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
  • Wait 10 seconds.
  • Using a diagnostic scan tool, check the BCM Continuous Memory Diagnostic Trouble Codes (CMDTCs).

Is DTC B11D9:17, U3006:17, U3006:1C, U3007:17, U3013:17 or U3014:17 present?
Yes GO to Z4
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.

Z4 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
  • 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 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 BCM.
REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Removal and Installation).
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.

PINPOINT TEST AA : U3000:49

Normal Operation and Fault Conditions

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
BCM U3000:49 Control Module: Internal Electronic Failure This DTC sets when the BCM detects an internal failure.

Possible Sources

  • BCM
AA1 CONFIRM THE DTC (DIAGNOSTIC TROUBLE CODE) RESETS
  • Check vehicle service history for recent service actions related to the BCM.
  • Ignition ON.
  • Using the diagnostic scan tool, clear the DTC.
  • Wait 10 seconds.
  • Using the diagnostic scan tool, perform the BCM self-test.

Is DTC U3000:49 still present?
Yes GO to AA2
No The system is operating correctly at this time. The DTC may have been falsely set by the BCM causing the signal to momentarily stop and set the DTC.

AA2 INSTALL BCM (BODY CONTROL MODULE) PMI (PROGRAMMABLE MODULE INSTALLATION)
  • Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
  • Install BCM As-Built data from PTS following scan tool instructions.

Is DTC U2100:00, U2101:00 and/or U2200:00still 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 BCM.
REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Removal and Installation).
No The system is operating correctly at this time.
