Self-diagnosis of airbag system BTU (Basic Triggering Unit) with and without side airbag
Fault table for BTU airbag system
Notes:
-
◆ The following table lists all the faults that can be detected by the airbag control unit -J234 and printed out according to fault ident. No. Present faults with 5-digit number fault number are printed out only with the printer of V.A.G 1551 switched on.
-
◆ If a fault is continually present the fault lamp for the airbag system lights up until the fault is rectified and the fault memory is erased.
-
◆ If a fault occurs only occasionally or if the fault memory is not erased after the fault remedy has been carried out, the fault will appear on the display as a "sporadically occurring fault" (SP). On the right side of the display of the V.A.G 1551 a "/SP" appears and the fault light remains on.
-
◆ If defective components were detected also check wiring to the components for short and open circuits according to the current flow diagram.
-
◆ The 3-digit fault type number appearing next to the fault code is a data code which can be ignored.
