The BCMC uses solid state drivers to control the output of several systems. When an overload occurs on any of these drivers, the BCMC disables the output and tracks the number of repetitive faults on each of these circuits. The module compares this number of overloads to 3 progressive thresholds established for each circuit. At each threshold, DTC U1000:00 sets along with the DTC associated with the affected circuit. For additional information, REFER to: Module Controlled Functions - Overview (419-10 Multifunction Electronic Modules, Description and Operation).

No	The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition. CLEAR the DTC.

J2 CHECK FOR CHARGING SYSTEM DIAGNOSTIC TROUBLE CODES (DTCS) SET IN OTHER MODULES

Using a diagnostic scan tool, retrieve all Continuous Memory Diagnostic Trouble Codes (CMDTCs).

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).

GO to J3

J3 CHECK THE BATTERY CONDITION AND STATE OF CHARGE

Check the battery condition and verify the battery is fully charged.
REFER to: Battery (414-01 Battery, Mounting and Cables, Diagnosis and Testing).

Is the battery OK and fully charged?

Yes

GO to J4

No	If the battery is discharged, DIAGNOSE the cause of the low battery condition. REFER to: Battery (414-01 Battery, Mounting and Cables, Diagnosis and Testing). If the battery condition fails, INSTALL a new battery. REFER to: Battery (414-01 Battery, Mounting and Cables, Removal and Installation).

J4 CHECK THE BCMC (BODY CONTROL MODULE C) VOLTAGE SUPPLY CIRCUIT

Ignition OFF.

Disconnect BCMC C1035D .

Ignition ON.

Measure:

Positive Lead Measurement / Action Negative Lead

C1035D-1 Ground

IS the voltage greater than 11.5 volts?

Yes

GO to J5

No	REPAIR the circuit in question for high resistance.

J5 CHECK THE BCMC (BODY CONTROL MODULE C) GROUNDS

Ignition OFF.

Disconnect BCMC C1035B .

Measure:
Click to display connectors

Positive Lead Measurement / Action Negative Lead

C1035B-31 Ground

Is the resistance less than 3 ohms?

Yes

GO to J6

No	REPAIR the circuit in question for high resistance.

J6 CHECK FOR CORRECT BCMC (BODY CONTROL MODULE C) OPERATION

Disconnect and inspect the BCMC 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 BCMC 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

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 K : U3003:17

Refer to Wiring Diagrams Cell 13 for schematic and connector information.

Normal Operation and Fault Conditions

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
BCMC U3003:17	Battery Voltage: Circuit Voltage Above Threshold	A continuous and on-demand DTC that sets in the BCMC when the BCMC detects higher than expected battery voltage on the voltage supply input circuit.

Possible Sources

Charging system concern
BCMC

NOTE: U3003:17 may be stored in the module memory due to previous battery charging or vehicle jump starting events.

K1 CHECK FOR OVERCHARGING DIAGNOSTIC TROUBLE CODES (DTCS) SET IN OTHER MODULES

Ignition ON.

Using a diagnostic scan tool, retrieve all Continuous Memory Diagnostic Trouble Codes (CMDTCs).

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).

GO to K2

K2 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).

GO to K3

K3 RECHECK THE BCMC (BODY CONTROL MODULE C) 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 BCMC Continuous Memory Diagnostic Trouble Codes (CMDTCs).

Is DTC U3003:17 still present?

Yes

GO to K4

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.

K4 CHECK FOR CORRECT BCMC (BODY CONTROL MODULE C) OPERATION

Disconnect and inspect the BCMC 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 BCMC 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

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.
