Technical pioneer sda-hu100 HUD not working

[Nenagh52]

worked when I picked the van up, stopped after a days drive but came on again, same happened on the recent trip to France, intermittent.
I can just about see the zero speed in the screen when I start the van.
Would welcome any suggestions, anyone know how its connected, I see on U tube that some are fitted to the OBD socket.

So why not check that it is securely plugged in? I do not have a HUD system, but it would seem that it would require an ignition "on" or similar connection, to at least illuminate the display, perhaps this has become disconnected?

So opened this panel this morning trying to see where is the HUD connected to/ powered from and the item in the blue circle is just hanging there.
No obvious place it came out of.
I don't think its from the HUD as the fault was intermittent but maybe it finally just came loose.

The connector with the obvious yellow centre is the OBD port, and nothing seems to have been attached there.

However on earlier models, the Vehicle Speed Output (VSO) signal is routed through the large black multiway connector behind your blue circle. Any sign of concealed mating connector, but I would expect at least three wires to the HUD, two power, plus VSO?

Your HUD unit is a Pioneer item, so cannot you do an internet search for installation instructions?

Thanks as always.
Have emailed pioneer again looking for the install manual. will look behind the "blue circle"
Plenty of sites offering to sell then manual but no induction that it is the correct one
In passing, are the heavy red cables to the leisure batteries?

No, connections to the habitation batteries should be to the converters panel at the base of the RH "B" pillar, or perhaps to the converters fuse on the battery fuseboard.

From Pioneer
The heads up display is not sold separately in the U.K. and is normally supplied factory fitted by the motorhome / camper van vehicle manufacturer so consequently we are unable to provide a wiring diagram.

Nenagh, did you ever sort this? Mine in Galway is, doing the same. Charlie

Just back from France, so catching up with emails.
No but have not looked at it in detail yet as have too much work on!
Will get to it.
Is yours intermittent?
What rig do you have?
Where abouts in Galway are you, roughly?

 

[charliehorse]

Mine is intermittent. It's the Pioneer rig. I'm on Rahoon. If I turn the engine off and back on, it usually works again.

Boxstar Freeway 630 2020 Headup display issues
Pioneer AVIC-EVO1-DT2-C-GR with head up display SDA-HU100-DUC
After 3 HUD display failures (2 replaced under warranty) Failure mode was where the brightness of the projector fails or so low it can only be read in darkness. Pioneer can’t repair as they have no spare parts
I decided to investigate the projector assy and discovered the LED light source was faulty.
Replaced the original LED assy with a CREE CXA1304 9V 5000K assy which has been working perfectly for the last month of travelling. Hopefully this might help as a replacement HUD unit from Pioneer is expensive ~£600.
The CREE LED is available from various suppliers for a few pounds.

Much obliged for this.
I can sometimes see it in the dark so I suspect I have the same issue
Would you mind penning a few lines on how you took it apart to get at the LED
Thanks

Remove 2 torx screws to get plastic cover over instrument binacle off.
Remove connector from bottom of HUD
Remove 3 screw’s holding HUD to binacle cover
Remove multiple small Philips screws and remove base plate of HUD
Remove several screws holding ASUS PCB in place
Flick white lock on PCB that secures the flexible cable from the projector then remove the PCB disconnect small 2 pin connector with RED and BLACK wires supplying the projector LED.
Now you can access the projector assy
Remove screws holding projector assy to HUD body.
You will then see the red and black power supply wires connected to the faulty PCB with the LED
Remove the heatsink from the projector assy 2 screws.
Then remove the heatsink pad (blue silicon type material)
Now you can see 2 small countersunk screws flush that hold the LED PCB to the projector body.
Remove screws and LED PCB. Desolder the Red and Black wires from the LED PCB and solder onto the replacement LED PCB.
The original PCB has a square 7mm by 7mm LED that fits in a recess in the projector body.
The new one is round 7mm diameter so won’t sit in. Just place it centrally over the recess then put a new double sided heat sink pad on the heatsink and fit the heatsink in place with the 2 screws this will trap the LED roughly centralised to the recess. Couldn’t find a suitable 7mm square LED so the only option was the round one. Not a perfect solution but it works.
Re assemble in reverse. Be careful when refitting the flexi lead from the projector to the ASUS PCB and close the white lock to secure.
Sorry don’t have good photos of the job. Not sure how confident you are doing this type of work?
Maybe I could talk you through it on a teams call or take mine apart and send more pictures.
I would recommend an anti static wrist band when handling the components just to be sure.

Best of luck

Jim

Much obliged for this and your kind offer of a chat, will get back to you once I get to it.
Replacing awning is my priority, got destroyed in a storm in France last week
The unsolder/solder piece is the only new thing but let's get that far first.
Can you send a link to where I might source the replacement LED.
Thanks again
