A complaint of reduced or dropping range may also be present.

NOTICE
If the DTC P0BBD00 presents with a different symptom code than those listed above, then this technical
bulletin does not apply!

NOTICE
If a vehicle presents a range complaint without DTC P0BBD00 stored in the Battery Regulation Control
Module -J840- (diagnostic address 008C), then this bulletin does not apply. For concerns relating to the
degradation of the total capacity of the high-voltage battery due to aging, refer to Technical Service
Bulletin 2071535. For other concerns related to range diagnosis, refer to Technical Service Bulletin
2071494.

Technical Background
In some high-voltage batteries there have been cells that demonstrate an increased self-discharge due to a
production fault. An increased self-discharge in individual battery cells can lead to a reduction in overall
battery capacity, and therefore a reduction of the range of the vehicle.
In the case of a cell module replacement, certain steps must be carried out in order to reset the data in the
Battery Regulation Control Module -J840- (diagnostic address 008C).

Production Solution
Improvements made to battery production process CW46/24.

Service
CAUTION
The warranty information in this bulletin only pertains to the additional steps required for diagnosis of DTC
P0BBD00. If a cell module replacement is necessary, the labor operations, required parts, and special
tools will vary by model and are not accounted for in this bulletin! Please refer to the repair manual for all
additional requirements.

NOTICE

This procedure applies to vehicles with a Battery Regulation Control Module -J840- (diagnostic address
008C) with software version 1041. If the -J840- software is at a lower level than 1041, ensure all
applicable campaigns are completed to bring the -J840- up to software version 1041.

NOTICE
This procedure includes a reset of the data in the Battery Regulation Control Module -J840- (diagnostic
address 008C). This will prevent the “check cell equalization” test plan (performed in campaign 93P7) from
incorrectly identifying cell modules as defective that have already been replaced.

1.

Complete the test plan populated in GFF for DTC P0BBD00.
‒

2.

3.

4.

Note which cell module(s) are being identified as defective through the test plan.

Check the vehicle history to determine whether the identified cell module(s) have already been
replaced within the last 30 days and are now being identified as defective again with DTC P0BBD00
and the same symptom code.
a.

If the identified cell module(s) have been replaced within the last 30 days, proceed with step 3 to
perform a terminal 30 reset.

b.

Otherwise, if the identified cell module(s) have not been replaced within the last 30 days, then
skip to step 4 below.

ONLY if required due to step 2.a above:
a.

Perform a diagnostic de-energization of the HV system using ODIS.

b.

Ensure the ignition is switched ON.

c.

Pull fuse SC28 briefly.

d.

Reinstall fuse SC28.

e.

Re-energize the HV system using ODIS.

f.

Erase all DTCs.

g.

If the fault P0BBD00 does not return, then no further diagnosis or work is necessary, and the
vehicle can be released.

h.

If the fault P0BBD00 returns, then proceed with step 4 below.

ONLY if required due to step 2.b or step 3.h above:
a.

First, replace any cell module(s) as directed by the previous GFF test plan’s results, and in
accordance with the instructions outlined in the repair manual. Proceed with the following
additional steps only after the cell module replacements are complete.

b.

Perform GFF > Special Functions > software configuration > via action code > 8CHVHDM1041

c.

Perform GFF > Test plan > Select self test > 0019 – Establish bus sleep mode

d.

Perform GFF > Special Functions > software configuration > via diagnostic address > 008C

e.

Perform GFF > Test Plan > Select self test > 0025 – VKMS adaptation
