nissan200sx.dk Posted October 12, 2012 Report Share Posted October 12, 2012 Hi. I am a bit worried that I may have made a fault error code 40. (40 cm from the screen... ;-S) I have made the start of my new wiring loom, but didnt have in consideration that speed sensor signals need to be an shielded wire. The lenght of the first part in wire wrap is 60cm, is that too much unshielded wire for digital input / speed sensor. The sensor is the ABS sensors. I will use all 4. (Left and right / front and rear) Digital input 2, 3, 4, 5. How important is it to use shielded wire for ABS sensor signals? (With my s13 sensors / hubs the calibration was 2370). Now it is R33 GTR sensors and hubs. I have not counted if they are the same, but looks about the same. Will do a calibration when the car is running. Also, these sensors will be used for the ATTESA ECU, will this be a problem? Two things connected to the same sensors. Input to Vi-PEC and input to the ATTESA ECU.

Simon Posted October 14, 2012 Report Share Posted October 14, 2012 Shouldn't be a problem assuming that first length is all inside the cabin of the car. With the pullups turned off on the DI inputs it should not effect the ATTESA ecu. Quote Link to comment Share on other sites More sharing options...
nissan200sx.dk Posted October 14, 2012 Author Report Share Posted October 14, 2012 Great. Its been shortened ~15cm further, and the start of wiring loom is inside car and away from main power wires. Quote Link to comment Share on other sites More sharing options...
nissan200sx.dk Posted October 14, 2012 Author Report Share Posted October 14, 2012 Wiring for ABS sensor with pullup set to off should be? One wire to the digital input, and the second wire connected to sensor ground (green)? Quote Link to comment Share on other sites More sharing options...
Simon Posted October 14, 2012 Report Share Posted October 14, 2012 One will be ground (this can be through the ATTESA system) The other can be shared and run to the DI on our ECU. The pullup is configured in the DI setup and should be set to off. Quote Link to comment Share on other sites More sharing options...
