Technical Background
In some cases, the Electronic Stabilization Program (ESP) function test may not end on its own creating a 01486 fault
code in the Antilock Brake System (ABS) -J104-.
Service
The only way to end the test is to enter basic settings group 103 under address 03 – ABS. As soon as 103 is entered,
the display should read “function test inactive” indicating it has been turned OFF. The “Activate” button should not be
used.
Check ABS fault codes to see if the test was completed fully. If not, repeat using basic settings 93 or the test plan
under Guided Functions.
