That looks interesting!
What does I can't find the attachmentThat looks interesting!
What does I can't find the attachment
Yes I'm going to take the ecu out and take it apart and check for moisture/corrosion, but I thought if am getting +5v dc at the RH connector and Kernit's Nanocom says "sensor short to another sensor", then it can't be the ECU ?That fault is a common indication of an ECU fault. Worth checking that the connector to the ABS ECU is not wet or corroded.
Logically, the only way a sensor can short to another is inside the connector at the ECU or within the ECU itself or a short in the loom, unless a Nanocom can't actually diagnose a short circuit in the sensor itself ? Also +5v dc at the sensor plug would suggest the ECU is ok.Eye hasunt tried it yet
If nanocom refers to a non existent sensor (open circuit) as short to another, then the wabco ecu must only have limited options available. Perhaps they never considered a sensor would failLogically, the only way a sensor can short to another is inside the connector at the ECU or within the ECU itself or a short in the loom, unless a Nanocom can't actually diagnose a short circuit in the sensor itself ?

Yes you would think so. Though i can only talk from personal experience with the fun I've hadAlso +5v dc at the sensor plug would suggest the ECU is ok.
950 ohms on both fronts. It's got me proper baffled - 2 brand new sets of sensors and a new cv joint so far as the reluctor ring was cracked, but Kermits has no errors with a cracked reluctor ringWhat's the Ohms across the sensor?
When mine comes up with that message its always (twice) been the OSF Sensor gone Open-Circuit.
The minimum is about 1200 Ohms I think.My replacement is 1.23k if i recall. Isn't 1.2k the lower limit? Someone else will know better than i
i think its anywhere between 950 and 2000. The nearside one doesn't come up faulty - maybe they are both too low and the ecu isn't recognising either of them ?My replacement is 1.23k if i recall. Isn't 1.2k the lower limit? Someone else will know better than i
5 volts at the sensor does not mean there cannot be a short between sensors in the ECU or connector.Logically, the only way a sensor can short to another is inside the connector at the ECU or within the ECU itself or a short in the loom, unless a Nanocom can't actually diagnose a short circuit in the sensor itself ?

Two failed ECU's?Someone from range rovers.net posted this a while back :-
"My car is a 2000 Thor with the later black box ABS / Traction control. Failure modes include open circuit across the signal wires and several cases of 'sensor X short to another sensor'. Although this is often a symptom of a failed ECU, I have tried an alternate ECU and it gave the same faults. ".
