Measure
Fault concern: Door soft close – B122D29: Lock unit for central locking implausible signal
Containment action:
1. Check door SC EA41 has been completed (not USA region)
2. Apply MOD measure for door CM - the specific SVM code is 4V0DOORS05 (NOTE: The word DOOR in the SVM code is all letters) this will deliver
software level 57
3. If the Diagnostic Trouble Code (DTC) B122D29 will not erase then check for damage to the latch (see Figure 1a)
Figure 1a
–
Open the door and inspect the latch mouth in the areas shown in figure 1a, it may be necessary to push the ratchet into the 1st or 2nd
position to get an unobstructed view. Note 1 - Ratchet – Ratchet mouth is the slot where the ratchet grips the striker. The ratchet
contains a steel core which is over moulded with a black plastic coating. It is this black plastic coating indicated by yellow arrows that
requires inspecting
Figure 1b
Figure 1c
–
Replace latch if damage to the plastic coating is seen, as in examples, figure 1b, bulging and deformed and, figure 1c, torn
3. Advise reference door soft close time out features – 3 following scenarios
3.1. Door open and closed by soft close operation for circa 30 times in ten minute window, the soft closed will time out and it will take 1 minute for
each operation before full functionality will be restored
•
Each ‘Power latch’ operation increments a counter by 1
–
Every minute with no power latch operation reduces the counter by 1
–
If the counter reaches 30 within 10 minute period, ‘Power latch’ will stop operation, requiring 30 minutes of no operation to decrement the
counter back to 0
–
i.e. 30 minutes is the longest time to wait for full functionality to be restored
3.2. Door interior handle or exterior handle held in the not at rest position, partially open for circa 5 seconds the door soft close will time out and on
ignition cycle will begin to function again if the door is fully open
3.3. Door soft closing and then manually overridden by opening door, the soft close will time out and in this case the door requires to be fully closed
and then the ignition cycled to reset the function
Note: in the event of a repeat failure please raise a DISS technical concern
Fault concern: Door soft closed – B125F01: Closing assist motor electrical error
Figure 2
1. In the event that fault code B125F01 is present ensure short motors (109,3) are fitted (see Figure 2)
2. Check door SC EA41 has been completed (not USA region)
