Eac Fail Message On Dash

FIRST OF ALL, TO THE MODS OF THIS SITE. I AM NOT INTENDING TO ADVERTISE MY SERVICES BUT LOOKING ON THIS FORUM IT SEEMS EVERYONE HAS HAD THIS FAULT....EVERYONE HAS PAID DEALERS FOR MAF'S, SENSORS, INJECTORS, ECU'S AND COMBINED LABOUR CHARGES THAT WOULD FEED A THIRD WORLD COUNTRY FOR A FEW YEARS..... WELL I AM AN INDEPENDENT AUTO-ELECTRICIAN BASED IN BRADFORD....I USE THE SAME EQUIPMENT THE DEALERS USE (IDS, ETIS AND ECAT) THE PROBLEM IS THE TECH GUYS ARE NOT USING THEIR TOOLS AND RESOURCES PROPERLY. FIRSTLY EAC FAIL SYMPTOMS CAN BE QUITE LIKE OTHER FAULTS SUCH AS SENSORS/ACTUATORS ETC AND ALSO AUTO BOX FAULTS (I WILL WRITE A BOOK ON THIS OTHER COMMON PROBLEM SOON!!)

1. EAC FAIL. EAC = ELECTRONIC ACCELARATOR CONTROL.

THE PARTS OF THIS SYSTEM ARE A THROTTLE PADAL THAT USES ELECTRICAL SENSORS INSTEAD OF THE OLD CABLE TYPE. THE SIGNALS FROM THIS PEDAL ARE SENT TO THE ECU TELLING IT THE DRIVER IS REQUESTING 20%, 50% FULL THROTTLE OR WHATEVER YOUR RIGHT FOOT IS REQUESTING. ONCE THE ECU GETS THIS INFO IT TELLS THE ELECTRONIC THROTTLE MOTOR TO OPEN THROTTLE 20% 50% FULL THROTTLE ETC. NOW THE THROTTLE BODY ALSO HAS A SENSOR CALLED A "THROTTLE POSITION SENSOR". THIS SENSOR TELLS THE ECU HOW FAR OPEN THE THROTTLE IS IE 20% 50% FULL THROTTLE. SO ON A GOOD SYSTEM RIGHT FOOT REQUESTS PERCENTAGE> ECU READS THIS INFO AND TELLS TROTTLE MOTOR HOW FAR TO OPEN> THE THROTTLE POSITION SENSOR THEN READS THE ACTUAL THROTTLE POSITION AND SENDS THIS INFO TO THE ECU> THE ECU COMPARES REQUESTED PERCENTAGE AND ACTUAL PERCENTAGE AND IF THEY MATCH YOU HAVE A HAPPY CAR.THE PROBLEM IS WHEN THE ECU DEVELOPS A "SLIGHT FAULT" AND AS THE ECU DOES NOT DIAGNOSE ITSELF IT WILL TELL THE TECHY THE FAULT IS PEDAL, TP SENSOR OR THROTTLE MOTOR OR WIRING AND CONNECTORS. YOU HAVE ALL HEARD THE SAYING "THE COMPUTER SAYS NO" WELL THE CASE WITH FORD DEALERS IS THE COMPUTER SAYS "CHANGE THIS THAT AND THE OTHER AND KEEP TRYING PARTS TILL ITS FIXED AND BILL CUSTOMER FOR ALL PARTS" PROBLEM IS AFTER DEALER HAS CHANGED EVERY PART OF THE SYSTEM TO NO AVAIL THE TECHY FINALY SAYS "IT MUST BE THE ECU AND QUOTES SAID CUSTOMER OVER £1000 TO SUPPLY, FIT AND CODE A NEW ECU. OK THIS NORMALLY FIXES THE CAR BUT AT WHAT COST?????

NOW FOR THE GOOD NEWS (AND THE BIT MODS MAY DEEM ADVERTISING) I HAVE REPAIRED MANY FIESTA, FUSION, C-MAX, FOCUS ETC WITH EAC FAIL AND NEVER FITTED A NEW ECU!! IN FACT I HAVE DONE THAT MANY I NOW CHARGE A SET RATE FOR THIS REPAIR. IT SHOULD BE NOTED THAT ON ONLY ABOUT 4 CARS HAS THE FAULT ACTUALLY BEEN THE PEDAL/SENSOR/MOTOR ETC AND THIS IS SO RARE I AM HAPPY TO BUY THESE PARTS OUT OF MY FEE AND WORK FOR FREE IF THIS WAS THE CASE.

I WOULD NEED THE CAR FOR 3 HOURS IN BRADFORD AND IT WOULD NEED A GOOD battery AND A TENNERS WORTH OF JUICE AS THE FINAL STAGE OF THE REPAIR IS A TEST DRIVE UNDER ALL CONDITIONS INCLUDING MOTORWAY. THIS ALLOWS THE ECU TO RE-LEARN/ RE-ADAPT ITS VALUES AND ALSO CONFIRMS THAT THE CAR HAS BEEN REPAIRED AND TESTED UNDER ALL DRIVING CONDITIONS INSTEAD OF DRIVING ROUND THE BLOCK AND SAYING IT SEEMS FINE NOW

SO IN A NUTSHELL IF YOU WANT YOUR CAR REPAIRED FIRST TIME KNOWING EXACTLY HOW MUCH ITS GOING TO COST FEEL FREE TO CALL ME FOR A CHAT, THANKS STEVE 07518 722699.

IF THE MODS FEEL THIS POST BREACHES FORUM RULES BY OFFERING TO FIX PEOPLES CARS FEEL FREE TO EDIT RATHER THAN REMOVE THE THREAD AS I THINK MY DESCRIPTION OF HOW THE SYSTEM WORKS MAY HELP PEOPLE UNDERSTAND WHAT IS GOING ON UNDER THE BONNET??? THANKS STEVE
