I have 2009 Volkswagen Jetta TDI diesel, they saying this car require CAN bus system instead kwp2000 (KWPS8FE9) My car showing on scanner.
My question for you guys; How does the protocol Id change ? maybe ECU computer defective? some people told me that OBD2 talking with different module from ECU ? Because of aftermarket radio changed ?
from the car:
Protocol: KWPS8FE9 ( it should be CAN protocol ) ECU Address(es): 1A
CAL ID: 02F300050D 1402 CAL CVN: 21DB
Bus Voltage: 13.50 PID Count(s): 9 DTC Count from Mode $01: 0
Consolidated Readiness: UUCUUUUURUUU Supported Readiness: UUSUUUUURUUU
OBDII Readiness Monitor Details: Misfire Monitor Supported: N Fuel System Monitoring Supported: N Component Monitor Supported: Y Catalyst Monitor Supported: N Heated Catalyst Supported: N EVAP System Supported: N Miss Monitor Ready: NS Fuel System Monitor Ready: NS Component Monitor Ready: NS Catalyst Monitor Ready: NS Heated Catalyst Monitor Ready: NS EVAP Monitor Ready: NS
If you look at those monitors not supported and Is that why protocol Id not matching instead CAN bus system ?
Any help would be appreciated.
Best Regards.
