Vehicle instrument panel course

Theoretical and practical course to understand the operation, diagnosis, troubleshooting and repair of instrument panels as well as BSI boxes, Body and other comfort elements

 

We will explain the various failures that these devices usually cause as well as their programming and possible solutions in different brands and models of cars.

 

TECHNICAL CONTENT ACCORDING TO AGENDA

(We will discuss these topics using examples in various brands)

 

Introduction and Components 

- Eeprom Memories – Types

24cxx 93cxx 95xxx 35xxx

 

- Microcontrollers

mc68hc(7)05 solo eeprom mc68hc(9)08 solo eeprom

mc68hc(9)12 eeprom y rom, with or without security mc9s08 eeprom with security

mc9s12 eeprom/flash with NEC security

 

-  Engines

* Common fault – Cold solder

 

- Types of Engines

Brake or pinion mechanism:

-To remove the needles you can rotate

-Can be repaired

-Can be opened by hand

-It is easy to calibrate

-It is installed by VW, Mercedes Benz, Peugeot, Opel, Fiat and others

 

Without brake with copper winding:

-Not repairable

-You cannot set it by hand, we need to have the box connected

-Needles cannot be removed without the tool to hold the motor shaft bolt

-It is necessary to test with diagnosis to leave the needles firmly in place.

-BMW X5s mount it

 

Without brake with winding and pinion:

-The mechanism can be repaired

-Can be adjusted and tightened by hand

-They are resistant to removing needles

-Lo montan Mercedes Benz Vito w638, e39, e38, Iveco

 

- Speakers

-Sound function

-Soldier in-circuit

-They are easy to replace

-Common fault in VW and Audi panels

 

- Needles

-Can be replaced

-Main problem is the rear part and the adjustment eyelet split with the motor

-Difficult to obtain parts

 

- Voltage transformers

• Screen - Display

Clip:

-Easy replacement/replacement

-The integrated transformer usually fails

-For Audi A3, VW Touran, VW Golf, RB4 and RB8

 

Physical connector or needle:

-Easy replacement/replacement

-Black screen failure, loses liquid, glass part

-It is mounted by Ford Focus and several motorcycles

 

Fiber:

-Easy replacement

-Does not usually fail

-You should not touch the fiber with your hands

-When you move it you see the numbers blurred

-A common fault could be a lack of pressure against the plate

 

Welded flex:

-Can be soldered with direct tin or direct flat soldered

Soldier with tin:

-Very important to position well to be able to weld

-A common fault, letters/numbers are seen dimly or not at all

-Repair when the screen is scratched (resolder) cold welding problem

-When replacing the screen, in some cases you have to modify the voltage in the eeprom (according to the manufacturer)

 

Direct flat welding:

-Clean the surface well when removing the old one

-Microscope or magnifying glass is essential to be able to safely replace

-Place the flat very well in its position

-The welder must be in the shape of a 'T' and must be protected with rubber.

-Very difficult to replace

-Normally the screen is not damaged, it is soldered to the plate and screen

 

Repair of pixelated figures on the screen:

-Replace screen

-Correct checksum of the mileage figure

 

Repair failure of crazy needles or incorrect marking:

-Upload original file

 

Adjust original mileage:

-Compare files, replace line that changes (not the VIN one)

-The figure can also be recalculated in the same file

-Example: in Citroen, Mercedes Benz or BMW with adjustment to a lower figure they adjust themselves by pairing with/with other modules

 

Virginize paintings:

-It can usually be done with the original brand equipment / Pass Thru J2534

-If it cannot be virginized, it can be adapted by diagnosis (depends on the brand and model)

 

***PRACTICES in CLASS***

* Normal process of cloning a frame

* Normal process of cloning the eeprom memory or the complete micro

-Example: Audi box always adapt with VCDS - Vagcom to avoid errors, DEF, SAFE, etc.

*Renault frame repair process

* Toyota Prius frame repair

* Virginize and replace screen in Mercedes Benz box

* Virginize and clone a BSI drive
