Diagnostic Information
When using Link ECU, if using as Lambda 1 (device identifier 0) or Lambda 2 (device identifier 1), internal status and
error values will be displayed in PCLink.
Otherwise the CAN information will need to be used to determine problems (See Transmitted Information)
Lambda output defaults to zero when the module is not able to operate correctly.
Status Codes:
Code
Description
0 Off
1 Disabled
2 Initialising
3 Diagnostics
4 Calibration
5 Heating
6 Operating
If a fault is detected in operating mode, the module will cycle back to 'Initialising', then run through the setup procedure
again, halting at 'Diagnostics' if a fault is found.

Solution
Contact Link Technical Support
Check wiring, inspect sensor for damage.
Contact Link Technical Support
Check wiring, check battery. May occur
during cranking.
Contact Link Technical Support
Check wiring, inspect sensor
Ensure CAN-Lambda has good clean power
supply.
Check wiring, inspect connector. Typical
error when no sensor is connected.
Check sensor type, check wiring.
Check wiring, inspect sensor.
