Hi

After connectig to the car, my OBDuiono32k initializing process succesfull, but all PIDs have zero value.
Protokol is ISO 14230 slow, connection by mc33290.

I build simple logic analyzer and connect it to the Rx and Tx pin on processor.
the communication is


OBDuino to ECU 5 bit slow sequnce, switch to 10400 and send
OBDuino to ECU C1 33 F1 81 66
pause 55ms
ECU to OBDuino 55 E9 8F
pause 1sek
OBDuino to ECU C2 33 F1 01 00 E7

after this OBDUino periodicaly repeat the last sequence but ECU dont send answer.

I think this communication is not in order with ISO specification....

Please help me ....


OBDUino work :-)
I rewrited the initialization routine and switched off DTC reading.
