Customer statement / workshop findings
Customer statement
Customer unable to intermittently start the engine with the start button
Or
Engine starts but customer gets a pop up error on the Kombi
Workshop findings
In the event the Kombi pop-up appears the following DTC will also be stored within address 46 -Convenience system central control unit
B143C29: Access/start authorization button, Range/Performance
Technical background
The Access/start authorization button requires a certain amount of force applying to activate the internal switches
If all 3 switches within the Access/start authorization button are not engaged multiple times in a row the above DTC will store and the customer
will get a pop up on the Kombi. The engine however, will still start up
Production change
Currently under investigation.
Measure
TIP: A second technician may be required to assist with the following check
1) Place a thin layer of Electrical tape over the Access/start authorization button, this will protect it from scratches
2) With your ODIS tester, Navigate to:
0046 – Guided Functions – Read measured values – IDE08195_Access/start authorization button . Then display the below MVB’s:
•
HW signal Entry_and_start_authorisation_button_contact_1 [MAS06483]
•
HW signal Entry_and_start_authorisation_button_contact_2 [MAS06484]
•
HW signal Entry_and_start_authorisation_button_contact_3 [MAS06485]
3) Using the workshop tool WT10354 (Force gauge) and selected adaptor highlighted below (Figure 1), slowly press down on the Access/start
authorization button centrally (Figure 2) and record the force (N) which each contact point 1 to 3 changes from ‘Not operated’ to ‘operated’
