BMW E46 ZCS Coding Solution: NCS Expert or Vpecker Easydiag

Which tool is better for BMW E46 ZCS coding? BMW ICOM NCS Expert or Vpecker Easydiag diagnostic tool?

Basic info: ZCS information is saved in FA modules:

Option 1: E46 ZCS Coding with NCS Expert

You can use a cheap K+DCAN cable or ICOM A2 emulator to run with NCS Expert

Open NCS Expert software

In Menu, select “File”, then “Load Profile”

Select “ExpertMode”, “OK”

Then “VIN / ZCS / FA”

Then “ZCS / FA f. ECU” button

Then “E46”,“OK”

Then “KMB” or “EWS” in the E46, “OK”

Vehicle information

Add or remove options to our ZCS code:

You can find files under the codes “C: \ NCSEXPER \ DATEN \” directory with a name that follows the pattern “EXXZST.000”.

Here: “C: \ NCSEXPER \ DATEN \ E46ZST.000”

0982 00000000 0000000400000000 0000000000 1 // HARDTOP Hardtop in body color

0620 00000000 0000000000000000 0000000000 0 // Voice Control (Telephone)

0640 00000000 0000000000000000 0000000000 0 // Preparation for car telephone installation

0524 00000000 0000000000000000 0000000000 0 // light automatic / Daemmerungsschalter f. Headlight from 9/01

0663 00000000 0000000002000000 0008040620 1 RADIO_NG / / BMW Professional CD54

What these numbers stand for:

0982: BMW Options

00000000: hexadecimal to add or subtract from our GM figure number.

0000000400000000: to add or subtract hexadecimal our toll SA figure.

0000000000: to add or subtract hexadecimal our number VN figure.

Therefore to add the option of BMW “HARDTOP” we have to add the number “0000000400000000” to our SA “00003A40C4BC74216” and to eliminate if we installed

GM: 646100006

SA: 00003A40C4BC74216 + 0000000400000000 = 00003A44C4BC74216
VN: 000A640628J

Now, encode new information in the modules that is stored

Code a new ZCS with NCS Expert:

Retrofit the original rear LED on E46, encode the new order of our vehicle.

In the file C: \ NCSEXPER \ DATEN \ E46ZST.000 find the option to retrofit the LEDS:

H LEDH N0997 0001000000 00000000 0000000000000000 1 // Nachruestung LED_HECK Heckleuchten LED-E46 / 2 u. E46 / C Facelift

Open NCS-Expert and follow the steps in the previous section “Obtain information from our vehicle ZCS”.

“Enter ZCS”

E46

“OK” when “VIN” leaving the default.

“GM”, “SA” and “VN” information

Remove the last digit of the “GM”, “SA” and “VN”. Check the “Calculate Checksum” box.

Add “00000000” to “GM”, “0000000000000000” to “SA” and “0001000000” to “VN”.

Then “OK”and“Back”

Go to code “ZCS” modules; information is stored in the “EWS” and “KMB”

“Change ECU”, “EWS”.

“Change job”, “ZCS_SCHREIBEN”

“Execute job”to complete the coding.

“Change ECU”, “KMB”.

“Change job”, “ZCS_SCHREIBEN”

“Execute job” to complete the coding.

Done! Have changed the vehicle order and reset/retrofit the ZCS module. Then, check it – just follow the steps to“Obtain information from our vehicle ZCS” And see if the values are correctly or not
