FORScan Modifications

[airline tech]

Assuming you are in the BCM - Module and you do not know what line you changed, you can try the reset tabs as noted above and in the video.

You may also try, backing out of the As-Built files and performing a BCM self-test, this will reset the BCM and any fault codes. This will not change the As-Built line that was altered, but it may at least get the lights to dim back down.

OKAY, I'm going say it and you won't like it. You shouldn't be using Forscan. You didn't even save the original settings and can't tell us what was changed. You are in danger of making changes that will brick your system and make your vehicle inoperable, maybe permanently.

Hi any help I have changed my settings on for scan and my tail light is brighter then my brake light any help please

Is it one tail light or both that are brighter? Do you guys still have rear fog lights over there? I had a Mercedes that came from Europe originally and I had one rear tail light that was bright and it turned out Germany wanted that light to be bright if you fog lights were on. Maybe you hit a line in Forscan concerning that? Just spitballing here.

 

[LB'sTremor]

Just another thought here have you added any lights or electric acessoiries? what makes you think it was a Forscan change?

I think he hit the nail on the head here - Euro spec vehicles have a rear fog light. I actually had a 2013 Ford Escape and swapped the lower reflectors for a pair of same year Ford Kuga rear fogs and lower brightness bulbs for a more factory "custom" effect.

I do agree that you should be much more careful - you can come close to bricking cars nowadays if you aren't careful

All sorted now but my number plate light comes on with brake light lol

IRC that PID gets its feedback from the wheel speed sensors, could be a traction control making it not do 50/50

Negative.

The traction control CAN NOT affect the axles when any 4x4 mode is selected (either via the TM switch or via the 4x4 dial selector). The chain driven transfer case practically binds the two drives shafts effectively the same result when a center locking differential when locked in the G wagon or Unimog. I want to be specifically clear that it’s not like a center differential except when it’s locked which practically doing the same thing by binding both drive shafts. We can easily test that by simply putting the Ranger in 4H(or 4L, though I would not recommend it) and observe the axles bind when try to do a tight circle on dry (non-contaminated) pavement. Traction control won’t be able to adjust anything and this binding happens without even selecting the lockers, simply because it’s impossible to vary power between the shafts. Only thing the truck can do is cut power but then truck will just sit still. It’s simply just not possible. With variable braking, the only thing the truck is able to do is vary power between the two wheel only within the same axle. In 4x4 (4H or 4L), the traction display IS CORRECT when it’s showing power variation between two wheels within the same axle (lockers disengaged) but it IS NOT CORRECT when it show power variation between the axles.

Mine’s a 21 tremor XLT with front & rear selectable electronic lockers.

To clarify how TRACTION CONTROL works and how IT DOES AFFECT the axles in 4WD Modes.
You are missing an important factor - Traction Control is a 2-part system.

The INPUTs are the Wheel Speed Sensors

ABS Triggered -Automatically Applies - Modulated Brake Pressure to the spinning wheel.
Engine Reduced Torque - Momentary Reduced Engine Torque - for faster recovery of spinning wheel.

Note: This description would be for a Traction Control, wheel slip (spinning faster) than other wheels scenario.



4WD Vehicles

• With the transfer case in 2H, pressing the stability control-traction switch for less than 1 second disables engine only traction control, trailer sway control and ESC .
• With the transfer case in 2H, pressing the stability control-traction switch for more than 5 seconds disables engine only traction control, brake traction control and trailer sway control.
• With the transfer case in 4H, pressing the stability control-traction switch for less than 1 second disables engine only traction control, trailer sway control and ESC .
• With the transfer case in 4H, pressing the stability control-traction switch for more than 5 seconds disables engine only traction control, brake traction control and trailer sway control.
• With the transfer case in 4L, ESC is automatically disabled without pressing the stability control-traction switch.
• With the transfer case in 4L, pressing the stability control-traction switch for more than 5 seconds disables engine only traction control, brake traction control and trailer sway control.

On vehicles equipped with a locking rear differential, engine only and brake traction control are automatically disabled when the rear differential is locked.



Traction Control

The ABS module continuously monitors and compares the rotational speed of the drive wheels in relation to the non-driven wheels. When the drive wheels begin to spin faster than the non-driven wheels, the ABS module modulates brake pressure to the appropriate brake calipers by opening and closing the appropriate solenoid valves inside the HCU while the hydraulic pump motor is activated (brake traction control). At the same time, the ABS module calculates how much engine torque reduction is required to eliminate the wheel slip and sends this torque reduction message to the GWM over the HS-CAN2 which relays the message to the PCM over the HS-CAN1 . The ABS module also sends a traction event message to the GWM over the HS-CAN2 which relays this message to the IPC over the HS-CAN3 . When the PCM receives the torque reduction message, it adjusts engine timing and decreases fuel injector pulses to reduce the engine torque to the requested level (engine traction control). When the IPC receives the traction event message, it flashes the stability-traction control indicator (sliding car icon).

Once the driven wheel speed returns to the desired speed, the ABS module returns the solenoid valves in the HCU to their normal position, deactivates the hydraulic pump motor and stops sending the traction event and torque reduction messages. The PCM returns engine timing and fuel injectors to normal operation and the IPC extinguishes the stability-traction control indicator (sliding car icon). Once vehicle speed exceeds 100 km/h (62 mph), traction control is accomplished only through the PCM torque control.

The traction control system can be disabled by the driver using the stability-traction control switch. This is independent of ABS which cannot be disabled by the driver. The traction control switch is hard-wired to the IPC , when the driver presses the traction control switch, the switch sends a ground signal to the IPC . The IPC responds by illuminating the stability-traction control disabled indicator (sliding car OFF icon) and by sending a message to the GWM over the HS-CAN3 . The GWM relays this message to the ABS module over the HS-CAN2 . The ABS module takes no further action in regards to traction control until the driver presses the switch again in the same ignition cycle or until the ignition is cycled from OFF to ON. For additional information on disabling the traction control feature, refer to Disabling AdvanceTrac.

The ABS module disables traction control if there are any wheel speed sensor or solenoid valve Diagnostic Trouble Codes (DTCs) present in the ABS module. Traction control is also disabled if there is a communication error between the ABS module and the PCM . When traction control is disabled, the ABS module sends a message to the GWM over the HS-CAN2 . The GWM relays this message to the IPC over the HS-CAN3 to illuminate the stability-traction control indicator (sliding car icon).

I believe we’re saying the same thing while focusing the explanation from different angles.

While this is the in-depth signal profiles and configuration of the traction control components, I simply tried to explain why it’s impossible to have power difference between the drive shafts when the transfer case is engaged in 4x4. ABS, TCS, Terrain Management, Trail Control, HIV ABC, MSNBC, CNN, Nancy Pelosi etc. can’t cause the transfer-case itself to deliver different power to the front/rear drive shafts since they are bound together in 4H(4L) and effectively acting like a single shaft (TWSS).

Traction Control, ABS, Sensors etc. were brought up by someone else, not me. I think the power distribution display in the dash is confusing some of us into thinking the part time 4x4 in our trucks is same as the full time 4WD available F150s, which is not correct.

Ewwwwww. There is a lot of bad stuff in our trucks!

Anyone else enable the speed limit sign display and have American style signs? Unsure if I ever posted the photo but I’ve had this for a year plus now.

Yes. I enabled mine over a year ago and are American style.

I enabled mine a year ago but only get Euro signs which I believe is because mine is a 2019.

 

[Big Blue]

I've had it enabled on my 2019 for 3+ years with the European signs. I think the US signs were a firmware change with the 2020 MY. I also have an extra blank circle next to my speed sign that I believe is for passing zone or caution signs in Europe.

Is it possible to code out my ‘21 Ranger XLT’s need for a ACC sensor to give me regular cruise control functionality?

I have rebuilt a totaled Ranger and just don’t want to really replace it’s missing $500+ sensor. I don’t care for adaptive cruise and can live without crash detection. After replacing front bumper, grill, parking sensors, etc cruise control is disabled without the sensor. Lane keeping is also disabled, but I can live without that as well.
