muddy Posted August 18, 2013 Share Posted August 18, 2013 Afternoon all, I have just got a TD5 showing the above problem, plugged a T4 in and read and cleared 4 fault codes, went for a drive, lights came straight back on after some funky TC on what felt like one wheel, only two codes this time both relating to LHR sensor - air gap and wiring. Upon inspection the sensor seems to have been replaced at some point and was joined at the chassis with some terminals I have checked and heat shrunk these re-connected, cleared fault codes drove and lights came back straight away. Today I have checked resistance of the sensed 1050 +/- 50 both sides and checked supply voltage on both sides ( 4.8ish ) upon re connecting the sensors and Turing ign on lights go out and come on again straightaway, I have also plugged in a brand new hub and sensor assembly I have here and it does the same. I guess that the lights will always illuminate after bulb check as there is a serious fault stored however if the fault is rectified will the system function correctly with the lights on? If so I will re assemble and try it otherwise ill wait until I can get the T4 plugged in and try it. Can anyone tell me if the above voltage on the chassis loom seems correct? Cheers, Will.

Simon_CSK Posted August 19, 2013 Share Posted August 19, 2013 My understanding is you need the computer to reset the fault codes while there is still a fault the light will constantly relight at the appropriate point. With mine it is when I go over a speed hump too fast which I would think related to dodgy wiring. Quote Link to comment Share on other sites More sharing options...
