qu'il va se produire un ensemble de conditions logiques qui n'aura pas été prévu lors du désign..
Peut-on élargir le sujet un ti peu? Oui? Merci !
D'autres "conditions logiques" non prévues pour les autos fabrication-série peuvent aussi se manifester. J'ai une Matrix 2008 XR donc avec une pédale d'accélérateur standard ... pas de rappel pour moi. Cependant, suite à ma demande, Toyota m'avait fait parvenir les renseignements suivants concernant l'installation d'une radio mobile V/U. C'est sûr que ça peut s'appliquer à tous les véhicules 'récents' d'autres marques:

Thank you for contacting Toyota Motor Sales. We appreciate the opportunity to address your inquiry.
The installation of a mobile two-way radio system in your vehicle could affect electronic systems such as multiport fuel injection system/sequential multiport fuel injection system, cruise control system, anti-lock brake system, SRS (supplemental restraint system) air bag system and seat belt pretensioner system.
Vehicle electronic components could be damaged, and/or the proper and safe operation of the vehicle might be compromised if, for example, any of the following situations (and potentially others) existed:
* The transceiver is not "type-accepted."
* The power and/or antenna cables radiate RF current
* Routing of the power and/or antenna cables results in inductive or capacitive coupling
* Transmitter, feedline and/or antenna inefficiencies result in an unacceptable level of RF radiation exposure to the ECM's
* The standing wave ratio is unacceptably high
* The antenna ground plane is inadequate
Installation of a 2-way radio in Toyota vehicles should not present issues under the following conditions:
* The transceiver must be type-accepted by the FCC, and not modified in any way
* Maximum output power complies with FCC regulations (100 watts)
* All installation and operating instructions provided by Toyota and the equipment manufacturer must be followed closely
* The antenna must be installed as far away as possible from all vehicle electronic control modules (ECM) or other onboard computer/sensors
* The antenna cabling must be routed no closer than 20 cm (7-7/8 inches) to any ECM or other onboard computers/sensors
* Antenna and power cabling must not be routed along side or in conjunction with the vehicle's wire harness o It is always preferable to cross vehicle harness at right angles when possible
o Antenna and antenna cabling should be properly adjusted to obtain the lowest possible SWR (standing wave radio)
Disclaimer: The basic installation guidelines provided may be of assistance to you. Although they may not fully answer all your specific requests, Toyota must take reasonable precautions to limit our potential legal liability, because the full range of possible variables noted earlier could never be fully anticipated. Also, more detailed information that would provide the operational details of Toyota's electronic system is considered proprietary.
We do not recommend modifying our vehicles from their original factory specifications. Modifications could affect the vehicle's performance, safety or durability, and may violate government regulations. In addition, damage or performance problems resulting from the modification may not be covered under warranty.
It must be emphasized that, under the terms of Toyota's new vehicle warranty, damage caused by RF energy from a higher power mobile radio is specifically excluded from coverage because it is not the result of faulty materials or workmanship.
Accordingly, the owner assumes all such responsibility.
We recommend that you contact your local Toyota dealership for any additional clarification regarding the installation process that you may need.
