First start issue

[Richard Hill]

Have you tried 500kb? And are you sure your can high and can low wire s are round the right way?

Tried 500kb and that clear all of the errors but still no device is found. Here is my wiring diagram for the connector.

In all Link documentation White is CAN H and Green is CAN L, you have them written down opposite to that above.  Can you confirm CAN H & L are connected correctly at the ECU.

You are correct sir, the wires were reversed. I swapped them around and it find the device now but still no Lambda1is displayed. I get all green prior to starting the engine, once I start the car the errors return. Log file below. Thanks.

Can you post your current map file please?

Are you powering the CAN Lambda from a clean ignition switched +12Volt supply?  And are you grounding it through a solid power ground?

The power is from the ignition switch and it shows a solid 12.4 volt, ground is to the chassis. 

[Richard Hill]

one way to check if it is a power problem or not, is to connect the CAN lambda power and ground up to a separate power supply, usually a charged independent car battery works.  See if there is any change.

Failing that, i'm a bit stumped, although I would suspect Adam might be able to help in more depth.  

 

What does Lambda 1 status and Lambda 1 Error show before the engine is started?  Include a full log pre start up too if possible.

 

[Cnote0ne]

Lambda 1 Status show disabled/diagnostics and Lambda 1 Error show Ok. Here is the log. Thanks

Your CAN Lambda is stuck in the calibration phase.  Can you do is I suggested and power it from an independent source as a test.  Is your Lambda sensor the one supplied with the CAN Lambda?  Is it new?

Does it come out of calibration phase if you log for longer?

 

 

[Cnote0ne]

The Lambda sensor is new and came with the Link CAN-Lambda module kit. It stays in calibration with no change. I will source a separate battery to test your suggestion. Thanks.

Also, try this CAN stream on ID 950, and then do a full log.  This will help see some more of the CAN Lambda parameters.

I dont think it is "stuck in calibration mode", I think it has lost comms.  The ECU is just displaying the last message it received.  You can see that lambda temp is not changing - if had had comms the exhaust heat would cause it to change. 

This could be a CAN bus issue such as termination etc or it could just be power lost.  I would suggest you start with Richards idea of connecting it direct to the battery with a couple of temporary wires to rule it out.

Ah ok, so maybe a voltage drop out then. Would it not have recovered when the alternator cut in though?

Yes, if it was a temporary power loss it should recover.  I suspect it is not a temporary loss.  It could be a bus issue as I mentioned, but there is so little data moving it should not be a particularly error sensitive bus, so I think most likely a bad power connection.

Problem solved! some how it stop getting power. I switch the power supply and now I get AFR/Lambda. I also found ground wire was a little loose, not sure if that contributed to the list of issues.  I want to thank you guys for all the help.

Thanks Richard!
