Adaptation After Replacing Instrument Cluster
Adaptation (function 10)
Using the adaptation function, the following changes can be made and saved.
- Perform adaptation of vehicle keys
- Adaptation after replacing instrument cluster.
- Adaptation after replacing Engine Control Module (ECM).
- Adaptation after replacing instrument cluster and Engine Control Module (ECM).
Adaptation after replacing instrument cluster
NOTE:
- The instrument cluster (with integrated anti-theft immobilizer) is adapted to the Engine Control Module (ECM). If the instrument cluster is replaced, the new instrument cluster must be re-adapted to the Engine Control Module (ECM).
- After adapting the instrument cluster to the Engine Control Module (ECM), vehicle key adaptation must be performed.
- If no authorized ignition key is available, but the secret number is available, new ignition keys must be made and adapted to "Adaptation after replacing instrument cluster".
- Adaptation can be interrupted using the "C" button.
Requirements
- VAS5051 tester connected and vehicle On Board Diagnostic (OBD) selected.
- ignition switched on.
Procedure
- Insert old (authorized) ignition lock and switch ignition key into on ignition.
Display on VAS5051:
- Press selection -1- of vehicle system "01 - Engine electronics".
- Wait until the next indication appears on display.
Display on VAS5051:
1 - Control module identification of Engine Control Module (ECM).
2 - Control module identification of immobilizer
Control module identification, immobilizer (example)
WAUYP64B61NO04321 1) AUZ7ZOX1137197 2) 1) 17 digit VIN (Vehicle identification Number)
2) 14 -digit identification number of immobilizer
Using the 14 digit identification number of the ECM, determine the secret number via direct query of the system (like direct query of the radio code).
WARNING!
The secret number is only intended For internal use and must not be shared with the customer!
- Click on -> button
Display on VAS5051:
- Select diagnostic function "06 - End Output" in selection -1-.
Display on VAS5051:
- Press selection -1- of vehicle system "17 - instrument cluster"
- Wait until the next indication appears on display.
Display on VAS5051:
1 - Control module identification of the instrument cluster
2 - Control module identification of immobilizer
Control module identification, immobilizer (example)
XXXXXXXXXXXXXXXXXX AUZ7ZOX1137197 1) 1) 14-digit identification number of immobilizer
Replacement part instrument clusters already have a 14 digit identification number (this is necessary if instrument cluster and ECM are being replaced simultaneously). It is overwritten during adaptation of the instrument cluster to the Engine Control Module (ECM).
NOTE: If a used instrument cluster is being installed, it must first be switched free via a login procedure. The secret number For this must be determined via the 14-digit identification number of the used instrument cluster. Continue as follows after successful login procedure:
- Click on > - button
Display on VAS5051:
- In selection -1-, select the diagnostic function "10 - Adaptation".
Display on VAS5051:
1 - Enter channel lumber Max. input value = 99
- Select function "50" in button field -2- For "Adaptation channel 50" and press Q button to confirm input.
Display on VAS5051:
1 - Channel 50 read and test
2 - PIN ?
3 - Keypad - only direct input via the keypad is possible
4 - Sliding bar is positioned on 32000
- Press "Keypad" button -3-.
Display on VAS5051:
1 - Enter adaptation value Input value: 0 to 65535
- Enter previously determined secret number (of Engine Control Module (ECM)) in button field -2-, while inserting a 0 in front of the 4-digit number (e.g. 01915).
- Press -Q- button to confirm input.
NOTE: If the secret number is entered incorrectly three times, tester display will indicate "locked 10". This locking time an also be indicated in measuring value block 024 (display field 2). Adaptation is now locked For 10 minutes. This time is doubled after every third consecutive incorrect attempt, up to a maximum of 255 minutes.
- Wait until the next indication appears on display.
NOTE: If a malfunction occurs during adaptation, the following DTCs can be displayed:
- "Interference": CAN-bus not available or engine speed recognized (adaptation only with the engine standing still)
NOTE:
- "Adaptation not OK" Engine Control Module (ECM) cannot give out data (17-digit VIN, 14-digit identification number), since the control module is still new (factory condition) or the data is faulty.
- "System not OK": Engine Control Module (ECM) does not give out data, since it was previously used with a control module (instrument cluster) in another performance class (tuning-protection)
- "Key not OK: Data cannot be given out or accepted, because no key or no matching key is available.
If no malfunction is present, this display appears:
Display on VAS5051:
1 - Channel 50 read and test
2 - 17-digit VIN (Vehicle Identification Number)
5 - Sliding bar is positioned on 32000
In addition, the warning lamp in instrument cluster lights up.
- Press "Save" button -4-.
Display on VAS5051:
1 - Channel 50 save
2 - 17-digit VIN (Vehicle Identification Number)
4 - original value 32000 new value 32000
- Confirm new adaptation value by pressing the "take over" button -3-.
Display on VAS5051:
1 - Channel 50 Value 32000 stored
The warning light will go out approx. 2 seconds after successful adaptation and a short confirmation signal will be given (0.5 seconds light off, 0.5 seconds light on, light off).
- End function "10 - Adaptation" by pressing <- button.
Adaptation of the immobilizer to the Engine Control Module (ECM) has been completed.
- Perform adaptation of vehicle keys
