LOCATION DIAGRAM ANTIFTMODULE


No go! The anti theft system is cleverer than that and can't be defeated. The antitheft module is part of the ECM and is just a part of the many things this tiny but powerful computer controls. The ECM is inside the fuse box under the hood normally on the driver side wheel arch.

2004. Why is the blower motor not receiving power?


The blower motor relay in the auxiliary junction box under the hood is good ? All relays ? only one controls the blower motor ! The electronic automatic temperature control module turns it on by supplying a ground inside the module ! The 30 amp fuse for the blower motor is located in the under hood auxiliary junction box ! At the relay socket test for battery voltage at pins 30 an 86 ,power form 30amp fuse ! The other two pins 85 an 87 ,85 is circuit to the electronic temperature control module . You could test this part of the circuit too , with a test light or volt meter . But if no voltage to the blower motor ,could be the electronic temperature control module is bad !

What the electronic control module control on my 2005 cts


Did you check your fuses? You might have a blown ecm fuse or other fuses blown. Were their any additional wires connected to the battery that you may have ommitted? Do you have spark at the coil pack or the plugs? You may have a bad module. How does it sound when you crank it over? Does it turn over superfast? Could be timing. Check all these things and get back to me. Check the fuses and relays under the hood also.

I have an audi 500sel 93 manual AAH Engine, no fire to the plugs, car refuses to start. checked computer box, 2 crank sensors, modulator, the coils all tested okay and fuel coming to injectors ok. timing...


We will star a list of what is good.and what controls spark
1. crank sensor .you done it
2.ignition control module. located on the center of bulkhead,behind intake air hose
3.coils. you tested it.
4.ECM located under passenger side foot well

ECM no you got fuel,so lets leave it out
cranksensor okay you replaced it
ICM ignition control moduel.
no spark you cover everthing. has to be a loose or no contact connection somewhere, you covered it all.you might want to tap on the ecm., or check the fuse for power to junction the ones in the hood area those can blow and not give power to ignition system

Help my mercedse says display faulty visit workshop. it wont start. i just had a full sevice performed and was told it can drive far distances. the lights, radio etc work just zero response from engine


Have you checked your fuses? Check your owners manual for location of your fuse boxes. Normally under rear seat and under hood in mercedes. Check the reference card in the fuse box for any fuses corresponding to the engine,I.E. engine, Fuel pump,etc. Check those fuses to see if any are blown. If the fuses are all good then it is probably the ecm (electronic control module).
