This OBDII Electronic Control Unit Simulator is the perfect equipments for diagnostic, development and education purposes. The OBDII ECU Simulators generate several standard DTCs and allow setting five parameters (MAF, Lamda, rpm, car speed, temperature).
With this IC you can develop yourselves their own, economical circuit.
Description :
OE91C1000 is intented to help the OBD protocol programmer. With a few external component , this chip simulate a ECU with K-Line diagnose output. Most of SAE J1979 PIDs are implemented. The PIDs are variable using a pot. When the DTC input is low , three DTC are generated , freeze frame stored and MIL LED is on till a erase DTC command comes. ( MODE3 and 4 ). The OE91C1000 communicate at 10400 baud with keywords 08,08.
Features:
- Compatible with ISO 9141-2
- 2.7 to 6V operating range
- MIL LED output
- Only K Line communication
- Fixed or variable PIDs
- ECU address 0x33
- 5 Baud init process
- Physical and fonctional addressing
- MODE 1..4
- ISO9141-3 procedure possible
- Freeze Frame reading
