Case Number: S2108000056 Rev. D
Release Date:
August 2022
Symptom/Vehicle Issue: U0111-00 Lost Communication With Battery Energy Control
Module Set In The HCP. BPCM Offline, Multiple Low Voltage DTC’s.
Discussion: In very low ambient temperatures the BPCM may not wake up and
communicate. This will cause the HCP to set a U0111-00 Lost Communication With
Battery Energy Control Module. This could deplete the charge in the 12v battery and
could also cause multiple low voltage DTC’s to set. This could be caused by a variation
on some BPCM circuit boards.
Diagnosis: Determine what temperatures this issue began for the customer. If
temperature were in the single digits or below when the U0111-00 set. This SOL case
is applicable to your issue. Once the BPCM enters into a state of not waking up. It will
remain in this state until power is removed. Through testing, Engineering has
determined some BPCM’s will fail in very low ambient temperatures.
Repair: Perform the DTC diagnostics for U0111-00 Lost Communication With Battery
Energy Control Module. A small percentage of BPCM circuit boards may be
susceptible to failure in single digit ambient temperatures. If the DTC flow chart leads
to BPCM replacement and the faults set when single digit ambient temperatures
occurred, the BPCM should be replaced. Replacement will likely remedy the low
ambient temperature failure that some circuit boards experienced.
A revised BPCM is being developed which should completely rectify the low ambient
temp issue. Expected release date is 4nd quarter of 2022.
