My Honda KB1 spontaneously decided to turn on the PUH light. I've checked everything but can't find a solution. The OBD reader also does not turn off the error message. As far as I know, I didn't hit anything. Anyone have an idea?

 

Puh light?

 

Pop Up Hood system

 

Oh Gawd, I'm familiar with this.

Has someone reversed into your front bumper? If they've dented the flimsy crash bar & the three sensors aren't aligned within ten degrees of each other (IIRC) then you'll need a crowbar & hammer...

I've had that...

Got it all fixed and then later a pheasant committed suicide & blew up my bonnet.

 

Is the 'flimsy' crash bar & three sensors you mention on the graphic below?

 

It's 17.

IIRC, the three sensors are on another slide with the harness & module.

I think you'll need a dealer re-set after you've re-aligned them. Dealer can probably tell you the fault code.

Yeah, I've looked 'high & low' on the OEM vendor parts diagrams to find & understand anything related to the PUH system and came up blank.
I'm totally over looking something or it falls under another descriptor?

 

ETA - you'll Need a Honda Leg End slide - the Acura RL doesn't feature the anti-Darwin bonnet/hood.

 

That explains it!
I did not even notice / realize the OP is from the Netherlands.
Now, I'm wondering why he is even inquiring on a North American message forum?

 

The car is very rare in The Netherlands. Only 150 sold so i was taking a shot.

 

From sea to shining sea...

There was a UK Leg End forum, but that went the way of ToV a looong time ago.

How's the US DAF forum getting along..?

Seriously, it is a bit of a problem - a lot of the electrical stuff in 'handed' for RHD cars and there are some spec differences, also between UK & JP. Obviously, NL is LHD.

The PUH stuff is buried inside the SRS module, which makes replacement/repair a bit problematical. And it's a swine to get to.

Bull's best bet is to talk nicely to his local Honda dealer & see if they'll pull the error code first, for not too many Euros. Or pull the bumper cover (watch the temperature sensor wire - it's bloody short!) and get out a straight edge.
