I have just installed a GPS tracker in the Escape, my concern is that the
system imobilize the car via disrupting the fuel intake. The effect
1. Engine viabrates for few seconds before it shuts the engine down

My concern is that will it damage my car taking into consideration that
the car is still under warranty and there is a possibility jeopardize the
warranty coverage

Chips, forummer and Ford appreciate if you guys could enlight me on the
issue. I was given the assurance by the installer that it will not
damage my engine and the electronics of my car, but I do have doubts on
the assurance.

cicobecky,

It will not damage your engine, as it is just like running out of fuel.
The vibration is due to the engine not getting enough fuel, i.e. fuel
starvation and engine cutting out intermittently.

The engine behaviour should not be related to the tracking system which
would only activate when necessary, unless there is something which is
interfacing with the ECU to immobiliser it each time the engine shuts
down. Note that the ECU coding contains the immobiliser code for the
original security system and it is possible that this new one you added
conflicts with that system in some way.

Chips,
Normally, they would cut off the fuel pump relay, and also the starter
relay to immobilize the car. ECU will not be touched at all.

OK, Ivan, I know you know this subject very well so I won't argue! But I
tend to feel that any modifications which involve electronics can be
risky nowadays because the systems all rely on electrical stability and
one accessory which is not previously accounted for could screw up the
systems.

Yap Chips

I totally agree with you, actually I am against it but since it is the
insurance requirement to install it thus the company has to adhere to it
due to many of SUV got stolen now days. Co has lost about 5 SUVs for the
last 5 months thus they are taking precautionary measures.

Yap you are right as currently I am having problem as tnhe GPS and
Fords alarm system do not seems to synchronise thus been receiving phone
calls from the GRS service provider that the alarm seems to be trigered,
in addition the Ford alarm have been trigerred despite that it was not
armed in the first place.

cicobecky,

I'm not electronic expert, BUT all I know Escape is equipped with SMART
INTEGRATED electronic & engine management system. I tried before to install
after-market alarm, BUT the shop took 4 hour before they gave-up & finally
I decided not to install that alarm. The problem was, they can't even the
disconnect the cable connecting horn & alarm, cause immobilizer was
activated & I can't start my engine even with my immo+key.

As I said, they GAVE-UP after trying for 4 HOUR!!!!!

I would suggest you bring it to Ford SC & let the Ford laptop diagnos the
problem. BUT be prepared to answer them coz yours is still under-warranty!

Chips,

Yes, it is actually a challenge in this era of electronics in cars. I
actually saw an alarm installer, fixing an alarm to a continental marque,
tapping the power supply to the car interior courtesy light, caused a
short circuit to the car's ECU, because there was a feedback to the
dimming circuit. Fitting in a RM2K alarm, caused the company RM12K to
replace the car ECU.

With the newer cars, with the CAN/VAN Hardware addressing and Multiplex
architecture, it is a whole new risky ballgame.
