properly.
8. Connect the battery.
9. Connect the diagnostic tool to OBD connector.
10.Turn the IGN ON.
11.Read the DTCs and clear all the DTCs from
BCM ECU with the help of diagnostic tool.
12.Unlock security to BCM ECU. Please follow
the procedure available in service tool to
unlock the security access.
Caution
– This is an essential step without
unlocking the security access further steps will
not be executed.
13.Perform the following diagnostics activities
a.
Read HW, SW part numbers and it’s version
numbers of BCM ECU and compare against
server
i. Vehicle Manufacturer Spare Part Number
(F187)
ii. ECU Application Software Number (7241)
iii. Application Software Identification (F181)
iv. ECU Calibration Software Number (7242)
b.
If upgrade required or mismatch with part
numbers, then flash the BCM ECU with latest
software. Afterwards follow the above step
again.
14.METHOD 1 : Learn the RKE/PKE (remote key)
as per below mentioned procedure
a.
Unlock the vehicle and open the driver door.
b.
Turn ON->OFF->ON Ignition 6 times within 6
seconds and observe flasher feedback. Two
flashes of Left - Right indicator Lamps and

d.
BCM shall flash Left - Right indicator lamp
and Telltale twice. In parallel, doors get
locked and unlocked.
e.
Learn next Remote Key as per steps c and d,
if required.
Note:
Maximum four keys can be learned.
f.
On exiting learning mode, BCM shall give
single long flash.
Method 2 : Learn of RKE/PKE ( Remote key )
through Diagnostic tool
1. After BCM parameterization at EOL/Service the
tool should display message
‘Remote learning initiated’. On the same screen,
EOL/Service tool to prompt for ‘
enter number of
keys to be
learnt
’ (Tool should not have an option to operator
at present. To start with, tool should display
“default 2
keys to be paired”. If required more than 2keys to
be paired, Tool shall unmask this option upon
specific
