Pinpoint Test

1. Ignition ON.
2. Using a scan tool, perform BCM self-test.
3. Clear the DTCs  . Repeat the BCM self-test.

Is DTC U3003:16 still present? 

• Yes: GO to 2  .
• No: The system is operating normally at this time. The DTC may have been set due to a previous low battery voltage condition.

1. Using a scan tool, perform PCM KOEO self-test.
2. Retrieve the continuous memory DTCs  from the PCM.

Is DTC P0562, P0620, P0622, P0625, P0626 or P065B set in the PCM? 

• Yes: REFER to DTC CHART: POWERTRAIN CONTROL MODULE (PCM) .
• No: GO to 3  .

1. Ignition OFF.
2. Check the battery condition and verify the battery is fully charged. REFER to DIAGNOSTIC ROUTINE A : Battery Condition Test.

Is the battery OK and fully charged? 

• Yes: GO to 4  .
• No: REFER to SYMPTOM CHART: CHARGING SYSTEM .

1. Ignition ON.
2. Measure and record the voltage at the battery.
3. Using a scan tool, view BCM voltage PID (V_BATT).

Is the voltage within 0.2 volt of the recorded battery voltage? 

• Yes: GO to  7.
• No: GO to 5  .

1. Ignition OFF.
2. Disconnect: BCM C2280G.
3. Ignition ON.
4. Measure:

BCM			Ground
C2280G			Ground
Pin	Circuit	Measurement / Action	Pin	Circuit
1	SBF02 (YE/RD)		-	Ground

Is the voltage within 0.2 volt of the recorded battery voltage? 

• Yes: GO to 6  .
• No: REPAIR the circuit for high resistance. CLEAR the DTC.

1. Ignition OFF.
2. Disconnect: BCM C2280D.
3. Measure:

BCM			Ground
C2280D			Ground
Pin	Circuit	Measurement / Action	Pin	Circuit
25	GD233 (BK)		-	Ground

Is the resistance less than 3 ohms? 

• Yes: GO to 7  .
• No: REPAIR the circuit for high resistance. CLEAR the DTC.

1. Disconnect the BCM connectors.
2. Repair:
   • corrosion (install new connector or terminals - clean module pins)
   • damaged pins - install new terminals/pins
   • pushed-out pins - install new pins as necessary
3. Reconnect the BCM connectors and make sure they seat and latch correctly.
4. Operate the system and determine if the concern is still present.

Is the concern still present? 

• Yes: CHECK OASIS for any applicable TSBs  . If a TSB exists for this concern, discontinue this test and follow TSB instructions. If no TSBs  address this concern, INSTALL a new BCM. REFER to Body Control Module (BCM) - with Intelligent Access (IA)  or REFER to Body Control Module (BCM) - without Intelligent Access (IA) .
• 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. CLEAR the DTCs  .
