SIGNAL SPECIFICATION, ABS CONTROL MODULE
All values given are between the relevant terminal in column 1 and terminal #A8 or #A24 (ground), unless otherwise indicated in brackets.
Note. It is important that the breakout box is connected and that the ground terminals have been checked before readings are taken.
| U= | DC voltage in volts (V) | Ubat = | Battery voltage (V) | |
