SC845 Posted May 19, 2022 Report Share Posted May 19, 2022 Hi... after setting up CAN lambda several times, it is not giving any reading. It is a new unit. Attached is my log file, can someone assist? PC Datalog - 2022-05-18 11;08;12 pm.llgx Quote Link to comment Share on other sites More sharing options...
Vaughan Posted May 19, 2022 Report Share Posted May 19, 2022 The CAN Bus is connected properly and the unit is operating but it looks like you are getting a few fault codes from it, specifically 16 heated too long and 26 battery under voltage which says that your power supply to it is not good enough. @Adamw should be able to offer some recommendations on how to improve it.

Adamw Posted May 19, 2022 Report Share Posted May 19, 2022 Yep I would agree it looks like a power supply issue. Is it connected to its own dedicated relay or is it connected to some existing circuit that has other devices connected to it? If the power supply cant supply enough current or it has other devices connected to the same supply that generate significant voltage spikes it can generate the faults you are seeing. Make sure the supply is big enough and if it is connected to a shared circuit then try the capacitor as per the alternative diagram in the quick start guide.
