================

 

 

I thought I'd post a different FFH fact every so often, here's the first.

--

Transport Mode

(This is something the Dealer Prep looks for when getting a car ready for sale)

 

During vehicle build, some vehicle modules are set in factory mode including the IPC and the BCM. While in the factory mode, the IPC displays FACTORY MODE CONTACT DEALER in the message center. If the vehicle is set in factory mode, the system does not automatically revert to another mode and must be manually set to either the transport or normal operation mode. When the vehicle build is complete, the vehicle is set to transport mode. While in transport mode, the IPC displays TRANSPORT MODE CONTACT DEALER in the message center. Transport mode reduces the drain on the battery during longer periods where the vehicle is not used. Various systems may be altered or are disabled when in the transport mode. The vehicle automatically reverts to normal operation mode after being driven 120 km (75 mi).

Definitions:

IPC = Instrument Panel Cluster

BCM = Body Control Module

That's how my FFH was when I took the first drive, it had just arrived at the dealer and they let me take a drive in it before they did PDI.

The arrow is pointing to a shiny little box with wires attached.  What do I win?  ;)

Mmm, good try but no cigar.  You have one of those mounted in your trunk area too.  It makes things go Boom.

Now that you mention it, I ought to turn this into a quiz.  I have some pretty sneaky reference material.

Boom? I'm betting it is a sensor or control unit for the air bags?

No, not that kind of Boom.  Maybe I should have said 'makes things loud'.

Seeing SONY is stamped on the case, it's probably the subwoffer amplifier, in a Titanium.

Sony Radio Amplifier in a Titanium is correct!

The standard radio Amp is positioned there as well.

How about you ask the next one?

Factoid...

The gas pedal input is all electronically controlled.

Acceleration Control - Overview

The acceleration controls consist of the accelerator pedal and sensor assembly.
The throttle is controlled by an APP sensor on the accelerator pedal assembly. The APP sensor sends a signal to the PCM in response to throttle pedal movements initiated by the driver. The PCM sends a signal to the electronic throttle control which increases and decreases throttle position.
The engine management system electronically operates the throttle of the engine in response to throttle pedal movements initiated by the driver. In the event of a system failure, the engine management system provides a "limp home" mode which allows the car to be driven with limited performance.

--

 

Accelerator Pedal Position (APP) Sensor

There are two pedal position signals in the sensor. Both signals, APP1 and APP2, have a positive slope (increasing angle, increasing voltage), but are offset and increase at different rates. The two pedal position signals make sure the PCM receives a correct input even if one signal has a concern. The PCM determines if a signal is incorrect by calculating where it should be, inferred from the other signals. If a concern is present with one of the circuits the other input is used. There are two reference voltage circuits, two signal return circuits, and two signal circuits between the PCM and the APP sensor assembly. The pedal position signal is converted to pedal travel degrees (rotary angle) by the PCM. The software then converts these degrees to counts, which is the input to the torque based strategy.

By the way, a few years ago, I checked the possibility of a stuck open accelerator peddle causing a runaway that you couldn't stop with brakes as a Prius driver claimed in Cal. a few years ago. I floored my 2010 FFH and put the brake on with the other foot. The ICE died and the car easily came to a halt. The design of the eCVT systems does not allow a runaway to occur even if there was a multiple failure in the APP systems or a stuck peddle.

Yes, that's a built in safety feature, some descriptions in the following explanation may not apply to the FFH because it isn't supposed to be towing:

Brake Over Accelerator
The brake over accelerator feature may not be active during low speed operating conditions. This enables unique drive maneuvers such as trailer tow, boat launch and retrieval or operation in hilly environments where the operator may require the application of both the accelerator pedal and the brake pedal during low speed maneuvering. The brake over accelerator feature will be active at speeds greater than 16 km/h (10 mph).
In the event the accelerator pedal becomes entrapped, such as by an object lodging the pedal, the brake over accelerator feature will reduce engine power when the brake pedal is applied.
The hybrid vehicles achieve a result similar to the brake over accelerator feature by reducing power if the brakes are applied while the accelerator pedal is pressed.

Operators that rest a foot on the brake pedal when also applying the accelerator pedal may activate the brake over accelerator feature. The brake activation is detected by the PCM from the electrical brake switch. In addition to brake over accelerator comments, the customer may bring the vehicle in for repair to address concerns such as a hesitation/stumble or a lack/loss of power. In the event of a hesitation/stumble or a lack/loss of power concern, carry out normal vehicle diagnostics for the appropriate symptom code. If the brake over accelerator feature is suspect, the BRKOVR_ACTION, BRKOVRD_POSS and DIST_BRKOVRD PIDs will display a brake over accelerator event occurred.
In the event the brake over accelerator feature is suspected as the cause of the customer concern, explain to the customer the details of the override system as described above. Additionally, make sure the customer is aware that resting a foot on the brake pedal while driving may cause the activation of this feature. This also results in activation of the brake lights on the vehicle while driving.

Brake Over Accelerator

 

I couldn't help it and had to try it out, I just went for a short drive. Floored it a 35 mph, then stepped on the brake, It works just like its supposed to. I always wondered if there were an ICE runaway how would you stop the car. Now I know.

Manufacturers claim that even in conventional cars, a full throttle ICE can be stopped by full brake application quickly. Thr eCVT hybrids do it as part of the intrinsic design.

I had a '69 Galaxie 500 as a teen. And one time the pedal linkage broke and got stuck in the full throttle position. But fortunately applying the brake did triumph over the acceleration forces, and I was able to stop without incident.
