General Information: General Description

There is no difference in the AHB's hardware side according to a vehicle specialization, but there is a difference in its software side because the applied vehicle parameters differ according to a vehicle specification. The variant code should be stored in the AHB ECU' memory for normal AHB operation. When the AHB ECU is replaced, the variant coding is needed.

After replacing AHB ECU, pressure sensor calibration and PTS calibration are essential.
