BLIS cross traffic issue

Postby Bluevanman! » Mon Aug 17, 2026 2:50 pm

HI folks

I have a EX amazon Transit.

A 71 plate 350 eco Blue.

I git it from copart with the whole front end missing and have over the last few month got it back on the road and it's a fantastic van. Lots of dents but that's for another day to sort.

However I have 1 Fault left. It's pointing to a Indicator missing or shorted. I will fire my Toughbook up I a bit and get the exact code.

Basically I get 3 warnings. BLIS malfunction, Cross traffic malfunction, and Pre collision assist warning.

I replaced the front Radar unit and that's working. Haven't calibrated it yer because of this other code.
Replaced one of the rear lane assist modules from an exit same amazon van and the error codes pointing to that being faulty went away. It got beat up as they rear bumper corner where it is was badly damaged in the vans accident.

With the info does anyone know if these 71 plate vans have the cross traffic indicators in the mirror glasses? I know the later 2023 onwards do but not sure if mins did.
My D/S mirror was missing when I got the van so got a used powerful off eBay.

Any info gratefully received.

I have a series on YouTube showing the vans rebuild from merch to running.

Will post the video of the electrical issues here where you can see the problems;

So I have sorted the Cross traffic issue.

Couldn't get any further with the code for side LED markers not present or open circuit. Turns out my van originally had wing mirrors with the cross traffic LED's installed. After I added them and cleared the codes I could do the calibration.

So Lane assist is now working but Cruise inst. I successfully did the Alignment but I just get a Sensor not aligned warning now. Cruise won't work and the cross traffic system is now ok.

Is it as simple as the bracket might be bent or something???

This may be of no use in your particular case, but I can tell you that cruise will not work if any of the switches on the clutch or brake pedals are faulty, missing, or disconnected :)
