all errors are stored in BBS and summary sent to instruments from BBS
BBS must receive errors from other units, e.g. the ECU and they must be transmitted over CAN
100any value >2 makes red ring light up.TPS?
0-196 High
0-122 Low
As DTC is in BBS it must send a traction control input to ECU over CAN, may be this is it and it isn't actually TPS?
