adam_szr Posted April 24 Report Share Posted April 24 I've had any issue since install where my link CAN Guage will only update when the brake pedal is pressed. All other times it shows either -50/0 except when I've pressed the pedal, then it will show last known value. When the pedal is held, it updates in real time. I installed the Link Fury X and Link branded GuageArt CAN Guage at the same time, I've checked the wiring from the Guage to the ECU and it's all correct as per the instructions. I have the guage hooked up to CAN 2 (Pins 27 & 28) of the B connector. I've followed the GuageArt instructions for configuring both the ECU settings as well as the phone App configuration. I don't beileve the issue is with the app as the selected paramaters and screen layouts I've chosen display correctly. I beileve it's either a wiring issue or more likely a configuration issue with my CAN setup, but I'm unsure of what. Any help is appreciated. The car is a 1997 Toyota Supra I can provide more details about the build if required but the brake pedal and under dash wiring etc is all stock. Also, apologies this is my very first post so let me know if I've left anything out or you require any further info.

Adamw Posted April 24 Report Share Posted April 24 It could only be a wiring issue, the brake switch isn't even connected to the ECU so the ecu has no idea you are pressing the pedal. It sounds more like the CAN bus is being interrupted, but I would start by confirming you have 12V at the back of the gauge with the pedal both up and down.

adam_szr Posted April 24 Author Report Share Posted April 24 Thanks Adam, I'll check this, this morning. Wouldn't I have to have 12v to the guage when the pedal is depressed though? As the gauge remains illuminated and displays last known values? I'll confirm anyway Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 24 Report Share Posted April 24 My thought was the display may stay alive down to say 3V but the processing side may dropout before then. Quote Link to comment Share on other sites More sharing options...
adam_szr Posted April 24 Author Report Share Posted April 24 Removed gauge from dash Confirmed faulting state remained to ensure jostling the wiring had no effect 12.6v with ignition on then 12.2v with brake pedal input Quote Link to comment Share on other sites More sharing options...
adam_szr Posted April 25 Author Report Share Posted April 25 Okay, I worked it out. The CAN wires were spliced into the factory CAN circuit. I'm not sure why, my best guess is for OBD functionality or similar. I've removed the splice and everything works. Quote Link to comment Share on other sites More sharing options...
