Greetings from a Pom in New Zealand

I have browsed forums here for a lot of hours and what great knowledge there is!

Thanks to you all.

I have our 4 mates glowing on the dash of 03 MY Discovery. On interrogating SLABS ECU with Hawkeye, it informed me that RHF wheel sensor intermittent.

There is a long convoluted story of frustration and spanner throwing, but to cut a long and sad story short…

I replaced RHF hub/sensor.

Lights returned following short drive - but ECU now shows NO FAULTS.

Lights reset on key.

All wheel sensor showing a nice steady 2.2v

My SLABs ECU is a standard SRD 000150

Am I correct in saying the 04 MY SRD 500070 is a more stable unit and a good first point to change with such spurious faults?

Landrover Tech bulletin 70-01-05NAS certainly states:

11. If fault codes remain stored in the SLABS ECU as identified in this bulletin or no faults were found while carrying out the diagnostic procedure on the wheel speed sensor, refer to GTR section 70.65.08 and replace the installed SLABS ECU with a new SLABS ECU (SRD500070).

I have also been told that battery condition can affect this. Little mention of this in forums though. Thoughts?

To give some credence to this, just today the M and S transmission lights started flashing. There does appear to be common wisdom that low battery can indeed affect this particular issue - so I’m now wondering if they’re connected?

Any input greatly appreciated before I resort to an instant fix involving a can of petrol and a zippo.

Cheers

Hi, first of all check the battery and charging to be ok, eventually give it a full charge then see if the amigos and M+S lights are still coming on

then

Yes that's correct

check the fault code stored in the TCU, it might be coincidental if the battery is strong enough

Thanks so much Sierrafery.

Battery is old and as vehicle not primary, has been left to go flat a couple of times - still cranks well though.
It was 11.9v static when checked cold this AM.
Charging at 14.2v
Been on charge all day and will leave charging overnight.
Fingers crossed in the morning.
Cheers

If it goes down to 11.9 over night that battery is almost gone, measure voltage while cranking too and if it drops below 11 then you need a new one cos in short time the engine will not start even if it cranks
