-
Measure the resistance between the BCM C4227a-28, circuit VDB05 (WH), harness side and the DLC C251-14, circuit VDB05 (WH), harness
side.
-
Are the resistances less than 5 ohms?
Yes
CONNECT the negative battery cable. GO to I4.
No
REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
I4 CHECK FOR CORRECT BCM OPERATION
NOTE: Do not disconnect the high voltage cables or connectors in the following step.
-
Disconnect the BCM connectors.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect the BCM connectors and make they seat correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new High Voltage Traction Battery (HVTB). CLEAR the DTCs. REPEAT the network test with the scan tool.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the
network test with the scan tool.
