Thread: Intermittent Electrical problems

The engine fault is related to the SLABS so that points to sensor faults in addition to the SVS fault.

The CAN fault relates to the engine not reporting a valid torque figure.
I would have thought it should be the P1884 fault relating to missing road speed.
But the Nanocom doesn't always report correct codes, so who knows.

For my money the Engine and Auto faults are just a chain of faults reporting faults on other ECUs, and should be ignored until you solve the SLABS issue.

Have a look at the earth points in the passenger foot well for a start.
Also check the earth points behind the passenger side headlights.

Also should add I've installed a second SLABS unit SRD000150 from a 2003 D2 to have the CDL function. Had it in for about 3weeks with no problems until now.
Never had the three amigos prior to the swap but couldn't say if I had the other faults as I'd didn't have the Nanocom either. Faults a coincidences??

Will give the plugs another removal connection at the SLABS, already checked yellow/green wire at ABS module and the earths at the left hand light but will check in foot well.
Could also plug the old SLABS back in for a few days and see if they appear again?

Are there any recall numbers for these SRD000150 units?

No recalls. They were for SLABS units prior to SRD000070. SRD500070 was the designated replacement for SRD000070 and SRD000150 in the last revision of the Amigos Tech Bulletin, but that seems to be a "swap the ECU if all else fails" scenario.

The power windows are driven by the BCU. Given that you've been changing the SLABS I'd definitely be checking the connectors in that area.

Make a reasonable attempt to diagnose and if there is nothing obvious swap back.

So replaced the battery yesterday, was four years old and 11.5 sitting and dropping the 8 volts on crank/start. Could this cause faults due to low volts?
Also was getting some of the faults pop up (three amigos, m&s lights) when trying the passenger side window with ignition on and engine off.

Did have a small amount of oil at the ecu plug but nothing like when I did the injector harness a few months ago.

Also checked the yellow/green wire connection but haven't got to the connections at the BCU and SLABS.

Haven't had any light on two trips yesterday around 1hour combined, so we'll see!!
