Signal specification
General
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.
