The KW1281 simulator is a best suited tool for the development and testing of OBDII diagnostic programs and hardware. It has 5 user-adjustable and several fixed-value PIDs. The DTC button can be used to generate trouble codes and illuminate the MIL LED. The trouble codes can be cleared using a Service 4 request. Physical connection is made through a standard SAE J1962 connector.
Description :
OE91C1400 is intented to help to VAG protocol programmer. With a few external component , this chip simulate a ECU with K-Line diagnose output. Group reading are realised via 4 pots which simulates the 4 values in each group.
When the DTC input is low , three DTC are generated and MIL LED is on till a erase DTC command comes. The OE91C1400 communicate at 9600 baud as ECU address 0x01..0xFF.
Read ADC channels, group reading, read/clear DTC are egally implemented.
