Strange headlight turn signal link.

[cskins]

In my t4 California coach hightop I have a baffling problem. When the key is removed from the Ignition if the turn signal lever is moved to the left turn position the left headlight and taillight turn on. The same thing happens when the lever is moved to the right turn position the right headlight and taillight come on. It has led to a dead battery a few times when accidently moving the lever while putting up the curtains. The van had an immobilizer which has been removed. The problem occured before and after the immobilizer was removed. Any ideas anyone.

This is a specific deliberate function. It’s a parking at night mode. If you read your manual you can find out how it works and how to turn that function off.
The images below might help

I don’t believe the 4s had the Auto light option?

Anyway, it is the parking light function. The issue is with the head light. It should only be the side lights that are actuated I think. Check the wiring at the lights.

The attachments were for information only - some vehicles also wouldn’t have front fog lights…

Probably sidelight bulb is within the headlight reflector as on T5.1.

I don't think you can.

Turn the main light switch setting to “off “…or if on headlights I believe the parking light function is also disabled?

Not on my T5.1. Headlight switch Off. if Indicator stalk is On, L or R then the front and rear sidelights are illuminated on that side. Not sure if there is a warning beep when removing ignition key. There is an audible beep on removing key if Headlight switch On.

That highlights the importance of having the correct manual for the vehicle.
