71 03 34 0E 04(RS) 00 00), and Tool shall again
request the same after some time.
b)
BCM shall update this byte as “Keys Paired
(0x01)”, if all requested no. of keys paired and
routine executed successfully. When this status is
received by the Tool, it shall display ‘Key learning
paired successful’ to user. If the first key has
learnt successfully this byte update as 0x00, then
BCM should ready for next key learning and
update this byte as 0x01 until all requested
number of keys paired successfully.
c)
BCM shall update this Byte as “Key pairing
failed due to Timed out (0x02)”, If BCM not
received key response (Lock & unlock) within the
time, then it should update this byte as 0x02
before exit from routine. In this case Tool shall
display “Key Pairing execution is unsuccessful
due to Timed out for Lock
& Unlock press” message and exit from the
routine.
d)
BCM update this Byte as “Keys paring Failed
due to same paired key ID (0x03), if user presses
the already learnt key, then BCM should compare
it’s ID with the learnt & stored key ID and should
respond to tool as 0x03 for routine results
request. In this case the tool shall display “Key
Pairing execution is unsuccessful due to same
paired key ID” message and exit from the routine.
(BCM should do the comparison from the second
key ID onwards with all previous learnt key’s ID).
Whenever BCM going to update this byte as 0x02
or 0x03, it shall erase the previous learnt keys
ID’s from it’s stored memory and exit from the
routine execution.
- Byte 2 – BCM shall remember the no. of key
pairing and update this byte and also in memory
after successful paring is done for respective key.
Tool shall read the same and display & update to
the user.
If BCM identifies Timed out or same key ID,
update this byte as 0x00 for routine result
response, i.e, paired keys shall be erased from
memory and exit from the routine. If BCM is in
continuation of routine execution process for 1st
key then it shall update this byte as 0x00 upon
routine result response from tool (i.e., 71 03 34 0E
04(RS) 00 00), during 2nd key execution shall
update as 0x01(previous key paired status i.e, 71
03 34 0E 04(RS) 00 01), and Tool shall again
request the same after some time.
6. Tool shall request the Routine results to BCM
every 2secs of time till the routine execution is
complete either successful or unsuccessful.
7. BCM shall update DID 4429 with key ID after
each successful key paring.
8. After successful learning of all keys tool should
display “
Keys learning routine execution is
successful”
and shall stop further actions by user.
15.Update BCM ECU VIN with following
procedure
a. Turn the IGN ON again and Unlock security
to BCM ECU with the help of diagnostic tool.
b. Read VIN from BCM ECU (22 F1 90)
c. Write correct VIN in BCM ECU (2E F1 90 XX
XX . . . . . )
d. Read VIN from BCM ECU (22 F1 90) and
verify.
16.Configure the BCM ECU (parameterization of
BCM ECU) with following steps
a. Turn the IGN ON again and Unlock security
to BCM ECU.
b. Perform the parameterization as per vehicle
variant with the help of diagnostic tool.
c. Power Latch - Ignition->OFF->ON transition.
(Make sure is key is taken out).
d. Read and confirm configuration data from
BCM against server.
17.Read the DTCs and clear all the DTCs from
BCM ECU with the help of diagnostic tool.
18.Provide IGN off-on cycle.
19.Read DTCs from BCM ECU with the help of
diagnostic tool. If any DTC is present, follow
the respective troubleshooting procedure to
rectify it.
20.Execute Service Test Routine for BCM ECU
a. Execute BCM EOL Self-test routine (31 01
20 01)
b. Read the DTCs from BCM ECU with the help
of diagnostic tool. If any DTC is present
follow the respective troubleshooting
procedure to it.
c. Execute Input switch test routine (31 01 34
09 06)
d. Read Input switch test routine results with the
help of diagnostic tool. If any DTC is present
follow the respective DTC troubleshooting
procedure to rectify it.
MAJOR PRECAUTIONS FOR REPLACEMENT
1. While replacing the BCMs, it is suggested not to
touch the BCM pins with hand.
2. While tightening the screws, tightening torque
must not exceed.
3. BCM upper and lower covers shall not be
removed while verifying/replacing the BCM.
4.
All of the service tool instructions for BCM
replacement shall be followed
