Signal Specification

All values given below are between the terminals stated in column 2 and the ground terminal on the body for the control module.

NOTE: It is important to connect the breakout box and check the ground terminals before taking readings. The adapter has two terminals for the breakout box. The signals in the 84-pin connector are split between adapter terminals A and B. For some VIDA fault-tracing, the connectors are numbered #1A-#28A, #1B-#28B and #1C-#28C. This is because fault-tracing is used from previous model years. From and including model year 2003, the connectors are numbered #1-#84.

Terminals #1A-#28A correspond to terminals #1-#28
Terminals #1B-#28B correspond to terminals #29-#56
Terminals #1C-#28C correspond to terminals #57-#84.

U=	DC voltage in volts (V)
U_bat =	Battery voltage (V)
U_low =	Voltage approximately 0 V
