1997-2003 E46 series street cars

This is considered a first generation CAN vehicle where the CAN wires do not go into the OBDii port, rather that connector has only K-line on it. You will have to splice onto the bus directly at or between the computers which talk on it. Those would include the ABS, steering sensor, instrument cluster, ECU, transmission controller and possibly the headlight control unit should all be on the same CAN bus. You may find the twisted pair colors as Yellow/Red for CAN+ and Yellow/Brown for CAN-, or Yellow/Black for CAN+ and Yellow/Brown for CAN-

  • On the instrument cluster pin 9 is CAN+ and pin 10 is CAN- 
  • On the ECU pin 36 is CAN+ and pin 37 is CAN-
  • available channels via CAN : Wheel Speeds x 4, Vehicle Speed, Brake Pres Front, Brake Switch, , ASC active + error, DSC active + error, Steering Wheel Angle, Engine RPM, Throttle Pedal, Throttle Pos, Engine Torque Driver, Engine Torque Actual, Engine Torque Request, Engine Torque Loss, Engine Torque Theoretical, Cruise Control Status, Cruise Control buttons, Clutch Switch, Air Temp Ambient, Air Pres Ambient, Gear, Oil Level Low, Oil Temp, Water Temp, Gbox Oil Temp, Fuel Used ECU, Fuel Low Switch, Fuel Level, A/C clutch, MAF error, Odometer.

1994-2013 E90 series street cars

  • available channels via CAN : Wheel Speeds x 4, Vehicle Speed, Brake Pres x 4, Steering Wheel Angle, Engine RPM, Throttle Pos, Air Temp Intake, Oil Temp, Water Temp. This list is what I have confirmed. There should be plenty more channels but I’ve yet to sit down with a car and reverse engineer more.
