Truck throwing warnings.

Hey guys my truck all the sudden throwing tons of warnings today, from hill decent to abs to collision and parking issues all at once.

WTF could be going on?

I had a 40" bumper light bar installed along with exhaust and front suspension perch picked up truck last night. I drove the truck maybe 120 miles with multiple start and stops with no issues.

Got in my truck and all those warning lights went off. Is it something the installer coulda done or is this coincidence?

Not sure what to do letting truck sit for a bit then I'll re start.

Ideas or suggestions?

Wondering if the installer could have done anything or is this just good ol random luck.

I drove the truck 120 miles then these lights all came on.

I just dont want to take to Ford and hear anything about mods voiding warranty BS

I think your installer nicked some wires or didn’t correctly integrate something. Ford will figure it out, and probably make you pay... then you have to fight installer.

Sounds like the ABS wires were damaged during your suspension install.

Yup you hit it on the head as soon as I told him what was going on I brought it back and he fixed it. Wasted 2 hours of my day though at his shop and scared me but oh well all good now.

Thanks guys

SSM 46139 - 2015/2016 -F-150 - Intermittent Loss Of Throttle Response - Multiple Warning Indicators And/Or Multiple Diagnostic Trouble Codes (DTCs)
Some 2015-2016 F-150 vehicles may experience intermittent loss of throttle pedal response, illuminated wrench, hill descent, airbag, anti-lock brake system (ABS) and/or advanced trac warning indicators and/or P2122, P2123, P2124, P2125, P2127, P2128 and/or P2138 DTCs. This may be caused by the Accelerator Pedal Position (APP) Sensor 14A005 harness being improperly routed behind the brake booster to brake pedal bracket. If the harness is improperly routed, loosen the bracket to free the harness. Inspect and repair damaged circuits before properly routing the harness. If the harness is properly routed, proceed with normal diagnostics in the Workshop Manual (WSM).

If needed, the wiring harness retainer clips can be relocated on the seat frame to prevent excessive wiring harness movement and chafing.
