Thread: Headlights switching on and off on their own?? What the hell could cause this??

Unfortunately, it's a sign your BECM has a problem.


I have a car here that self operates its fog lights & I know of other cars with self operating wipers.

That was not what I wanted to hear, hey?
Finances are about as cold as the weather...

Do you think it's worth trying a bypass of the lighting circuit and take it off the BeCM?

I guess it could be done. You'll probably encounter problems with dash/switch lights which might take a bit more work.


Do you know if the park lights are OK? If so, then controlling the main headlights separately might make it a lot easier.

The biggest problem might be if all the lights are effected.... Might just take a bit more research and observation.
It's really hard being at both ends of the truck at the same time and a shortage of mirrors...

When the headlights turn themselves off at night, do you still have dash lights?
If so, then the park side might be OK.


It might be worthwhile talking to Lee at Labtronx:

Lee knows an awful lot about P38 BECMs.


Or Rupert Prior (that's his username too) on here.

Hi Scott,
Is there any chance that any of these guys are in the Newcastle, Central Coast area?

HI guys,

Have swapped the BeCM Power board over from another vehicle but it made no difference.
Tried a fault diagnostic but no fault is being logged.
Have put a new headlamp switch in just for laughs and so far so good, I think?

Cheers,
Shirley.
