Powertrain Malfunction/ Reduced Power

[tjl2024]

Got my truck back today. Per the invoice, cell 21 in battery pack #3 failed. It was replaced and everything seems to be working now. It was out of service 2.5 weeks

Keep in mind that it will take a few weeks for the BMS to fully settle everything, so your SOC/range may be a little off from what you where used to during this settling period.

Thanks. That's good to know.

Suffering the same issue today, power is degraded (max 10% even show as 100%)

Hello! Send us a private message with your VIN and current mileage. Allow me to see what I can do to assist. Thanks!

I am having the same issue, but in my case I also lost power (turtle mode).

First time they kept my truck for 22 days and said it was a software issue. Two days ago I had the same issue, dropped the truck into another dealer, and now they are saying it is a fault acelerador pedal.

Both dealers does not give me confidence which means I cannot trust this truck anymore.

It is your battery array that is the problem. It happened to my vehicle three times before it finally quit driving. The first three times I removed the battery terminal and it reset, then it became a weekly reoccurrence and then became a daily occurrence and it completely stopped driving.

I am having a similar issue. Same error code but the truck drives fine. Only issue is my shifter won’t lay flat when this happens. Aggravating because the truck started doing this at 250 miles. Does it at some point everyday, but resets overnight.

Welcome to the forum, you might want peruse the BIG THREAD on this topic...

I wouldn't get in the habit of folding the shifter on a routine basis unless you're really in need of using the folding work space often, that shifter assembly is wonky at best!

Hey all,

Purchased F150 Lightning xlt ER about three months ago. About two weeks ago, a warning light popped up on the dash with a wrench indicating I need to schedule service. Inside the Ford Pass it showed the following description:

I scheduled service in which the dealership had my truck for several days. I just got a phone call from dealer saying it's a non issue and they were able to clear the warning. On the way home, the same exact warning light and description in Ford Pass appeared.

Anyone experience this? It's a bit frustrating only having put 2500 miles on the truck.


Thank you

Late entry, but just had the same thing happen. Dealer said "don't worry about it." I'm worried

This just happened to me too. Driving home from work, I got this error along with others as soon as I hit the ADAS on button. Other errors were 1 pedal drive, regen breaking, and ADAS unavailable. I stopped the truck, turned it off, and turned it back on. This restored normal operation of all systems. The wrench icon was still on, and said to schedule service soon.

Connected Forscan and found the following DTCs. The three in red were the only ones still active or intermittent.

• Code: P061A - Internal Control Module Torque Performance
• Code: P0887 - TCM Power Relay Control Circuit High
• Code: P1A13 - Hybrid Powertrain Control Module - Regenerative Braking Disabled
• Code: P087F - One Pedal Drive System Performance
• Code: U0401 - Invalid Data Received from ECM/PCM A
• Code: U0594 - Invalid Data Received From Hybrid/EV Powertrain Control Module 'A'
• Code: U0140 - Lost Communication With Body Control Module
• Code: U2108 - Adaptive Cruise Control

I then used Forscan to run the self-tests on all the modules that had or have faults. All self-tests completed with no faults found. A few cycles of clearing DTCs and restarting the truck resulted in a green panel with no faults. I went for a drive around the mountain. All systems nominal and still no DTCs.

So we'll see if this was a one-time anomaly I can pretend never happened, or a recurring event.

This is exactly what happened to me! Exact scenario. I hooked up my ODB reader and looked in Car Scanner:

P087F(00) [0x087F00]
Status: Pending, Confirmed, Test failed since last DTC clear

P061A(92) [0x061A92]
Engine control module (ECM), engine torque - performance problem
Status: Pending, Confirmed, Test failed since last DTC clear

P0887(00) [0x088700]
Transmission control module (TCM) power relay, control - circuit high
Status: Test failed, Test failed (current drive cycle), Pending, Confirmed, Test failed since last DTC clear, Warning indicator requested

P1A13(00) [0x1A1300]
HYBRID POWERTRAIN CONTROL MODULE - REGENERATIVE BRAKING DISABLED
Status: Pending, Confirmed, Test failed since last DTC clear

U0401(64) [0xC40164]
Invalid data received - engine control module (ECM)
Status: Test failed (current drive cycle), Confirmed, Test failed since last

U0594(64) [0xC59464]
Invalid data received from hybrid powertrain control module
Status: Test failed (current drive cycle), Confirmed, Test failed since last DTC clear

U2108(68) [0xE10868]
Status: Pending, Confirmed, Test failed since last DTC clear

All is good now so I am not too concerned but I might hook up Forscan and do self test. At the end of the day we're driving round a big computer and software is never 100%. Thinking, and hoping, this was just a random event.
