Original cluster:

The Jaeger cluster barely works

Suggestion:

read the pin code from both the Instrument and adapt it to the vehicle

Whattodo on pin 21 and 22 on the chip:

- With ECU programmers:

Eprom.set type,mcu,hc12,read,save.

eprom,set type,mcu,hc12,file,load,write.

Buy yourselfXprog- M programmer , C arprog , UPA-USB.

Pin 21 and 22jumperafter programming or wait 10 minutes.

- with Digiprog3:

Eprom,set type,mcu,hc12,read,save.

AUDI MM AB 8/2001 DIAGNOSIS / TACHO DIAGNOSIS

(Write down the exact ALWAYSold / incorrectMileage)

The diagnostic port is in the driver's footwell. Turn the ignition

on a vehicle. Connect plug ST16 the diagnostic port and the

DIGIPROG.

Select the program: cars / trucks - AUDI - MM 4 / 99- DIAG.

The DIGI PROG II shows you theold / incorrectMileage.

Enter thenew / correctMileage and confirm this.

Should be then after programming on the speedometer 999999 KM give

Theold / wrongKM value again so that the speedometer again the old /

false indicates KM. Now you build the speedometer and break it to the

seeboard. Solder the green and black wire to the same color marked

Arrows at. Now connect the blue and the green plug with

the speedometer and plug ST41 with the DIGI PROG (picture on the following page.)

Now select the program: cars / trucks - AUDI - MM 4/99 HC12.

The DIGI PROG shows you theold / incorrectMileage. Enter the

new / correctMileage and confirm this with the hook.

Now shows you the DigiProg II 5 min wait. Remove the connection

between the DigiProg and the speedometer, wait 5 minutes and build the speedometer

again. Alternatively, for 5 min. Wait, you can also like in the image on the

next page shows the pins 21 and 22 bridges.

Here necessarily the board from any power supply (Digiprog,

external power supply, etc.), Pin 21 + 22 bridge, and then you can use the tachometer

Immediately reinstall.
