Preparation for DTC Readout
1. Connect impulse counter scan tool or Hand-Held Tester (HHT) to data link connector (X11/4) according to connection diagram (see section 0).
Note:
Connect yellow wire from impulse counter scan tool to:
ABS/ASR control module (N30/1) socket 6
BM (N16/1) socket 8
SPS control module (N49/1) socket 12
ADS control module (N51) socket 11
TCM (N15/1) socket 10
