Transmitted Information

Link CAN-Lambda modules transmit the following information:
·
Lambda value
·
Sensor Temperature
·
Controller Error Codes
·
Controller Status
·
Pump Current
·
Battery Voltage
·
Heater Average Voltage
When connected to a Link ECU using the built in Link CAN-Lambda CAN communication mode, this information is
displayed on the following parameters:
·
Device identifier 0 (default)
·
Lambda 1
·
Lambda 1 Temperature
·
Lambda 1 Status
·
Lambda 1 Error
·
Device identifier 1
·
Lambda 2
·
Lambda 2 Temperature
·
Lambda 2 Status
·
Lambda 2 Error
·
Device identifier 2
·
Lambda 3
·
Device identifier 3
·
Lambda 4
·
Device identifier 4
·
Lambda 5
·
Device identifier 5
·
Lambda 6
·
Device identifier 6
·
Lambda 7
·
Device identifier 7
·
Lambda 8
Information is transmitted on CAN Id 950 + device identifier. Eg device identifier 4 transmits on CAN Id 954.
Transmission uses a compound message format (or sometimes called filter byte) with the frame index in Data 0.
CAN Id 950 (0x3B6) + device identifier
