Issue:
Some customers may report a higher than expected level of
hydraulic actuation system noise during brake applications. No
DTCs or warning messages are present on the instrument panel
and the vehicle is otherwise behaving as expected.
Cause:
Software compatibility between ABS and PCM software can result
in some irregularities in the management of brake requests
between friction brakes and regenerative braking.
Action:
Check the vehicle for any DTCs, particularly on ABS, BBM,
PCM, BCCM, and BECM modules.
If any DTCs are present then follow TOPIx diagnostic
procedures.
Check software level on PCM, if the suffix of the Vehicle
Manufacturer ECU Software Number is GAM then perform a
full software update to latest level. (Please find supporting

If issue is still present, conduct a physical check of brake
system pipework for any areas where pipes clash with body
structure or are not correctly mounted in the relevant pipe
clips.
