Hi Martin, Never did get to the bottom of this one - in fact, thanks for reminding me of this post...I guess I should close this out. Despite changing the EPB, ABS Module, SAS, Yaw Sensor, remaking all the wiring, giving it a new power feed and ground, changing the Transfer Case Module for a...

Does the triangle look like a mountain? if so, it is in Low Range - hence why your speed is so slow.

As above - sounds like a issue on the CAN.....start unplugging modules in turn until you find the one dragging it down....measuring the CAN resistance could also help.

No, never did - it stopped doing it just as randomly a it started doing it! All the above suggestions are good info to start on....check all earths, check all positives, check the fusible links, check connections to all three fuse boxes....check the pyro charge on the positive lead etc....all...

Yesterday I took some time to run some tests on the CAN - it is a long video where I disconnect everything from the CAN and one at a time connect an ECU and restest the voltage, then disconnect that and connect another one etc etc....so it took a short while - the vid is abot 37 minutes...

There is a terminating resistor in the Yaw Sensor and a second i nthe ABS module as the Yaw Sensor is connected to the ABS sensor via its own mini CANbus.... 120Ohm reading was because Ihad the TCCM disconnected which took the ABS Terminating Resitor out of the equation! I have a couple of...

Measured the voltages on HSCAN H and HSCAN L again - still reading a 1.34 - 1.37V ......hmmmmmm So went round unplugging in turn all the ECU's on the HSCAN on my D3 SAS - No Change EAS - No Change Terrain - No Change SRS - No Change ECM - No Change TCCM - No Change EPB - Voltage jumped to...

Further to: EDIT: DISREGARD THE BELOW - I HAD THE TCCM MODULE DISCONNECTED HENCE THE NO CONNECTION AS THE CAN LOOPS IN AND THEN OUT OF THIS>>>>>>doh!!!! Just been out to recheck some readings..... HSCAN H to HSCAN L resistance reading (battery disconnected obviously) is now reading...

Oh, I could be wrong, but from what I had researched previously CAN Low can be read as 1.33 to 1.5V - I will read the article with gusto and recheck! As per the wiring diagram: The Sensor receives 12V from Fuse 37 from what I can deduce.

CAN works fine and CAN Low should read 1.3 - 1.5vdc from what I have researched previously. Also, Signal Ground and CHassis ground are the same thing and resistance between both is full continuity. Also CAN High and CAN Low both share the same ground so it is not a CAN Low ground issue as it is...

Figures don't change at all - stuck at those in the video. Voltage to sensor is 12vdc from fuse 37, the same fuse that feeds voltage to the ABS ECU on pin 25 I think it is (Light Green). All other sensors report int othe ABS Module fine, Brake Switch is fine, all speed sensors read perfectly...

All earths check out perfectly, annoyingly!!! I will check the other areas you mention when I have calmed down a bit as this is doing my nut in at the moment! I gave the Yaw Sensor a new earth and also a new positive direct to the battery: But made feck all difference - I even unplugged the...

Cheers bud - I did a temporary replacement of the Yellow/Brown and the Yellow/Black wires as shown in the video to take any issues with those wires out of the equation - same faults and same Live Data readings. Next I intend to do a direct connection to battery (which is the Light Green wire)...

Thanks for the info above- a font of knowledge you are!! The waveform on the CAN goes immediately to short to ground when you turn the ignition off, which I am not 100% sure is correct as I am sure (and as listed above) there should be a period of time before the CAN sleeps - and when the CAN...

So a few weeks ago I ran new wiring from the Yaw Rate Sensor up to the ABS module: But that didn't change a thing, it still reported a circuit fault on both the Yaw and Laterl readings.... Also, the actual Live Data figures for the Yaw and Lateral didn't budge!! So, I have proved power and...
