STEP 5. KOS communication test
Using scan tool (M.U.T-III), perform the antenna communication
test to check that the exterior transmitter antenna (liftgate side)
is normal (Refer to P.42B-169).
Q:Is the check result normal?
YES:
Go to Step 6.
NO:
Perform troubleshooting for the diagnostic trouble

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.
(1)
Connect scan tool MB991958. Refer to "How to connect scan
tool (M.U.T.-III) P.42B-10."
(2)
Turn the ignition switch to the "ON" position.
(3)
Check whether the KOS-ECU related DTC is set.
(4)
Turn the ignition switch to the "LOCK" (OFF) position.
Q:Is the DTC set?
YES:
Diagnose the KOS-ECU. Refer to P.42B-18.
NO:
Go to Step 2.
STEP 2. Check KOS-ECU connector C-102 and liftgate lock
release handle connector F-09 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q:Are KOS-ECU connector C-102 and liftgate lock release
handle connector F-09 in good condition?
YES:
Go to Step 3.
NO:
Repair or replace the damaged component(s). Refer to
GROUP 00E, Harness Connector Inspection P.00E-2. Check
that the liftgate lock release handle works normally.
STEP 3. Check the wiring harness between KOS-ECU
connector C-102 (terminal No. 28) and liftgate lock release
handle connector F-09 (terminal No. 1) and lock switch
(liftgate side) connector F-08 (terminal No. 2) and ground.
NOTE:
Also check intermediate connector C-32 and D-12 for
loose, corroded, or damaged terminals, or terminals pushed
back in the connector. If intermediate connector C-32 and
D-12 is damaged, repair or replace the damaged component(s)
as described in GROUP 00E, Harness Connector Inspection P.
00E-2.
Q:Are the wiring harness between KOS-ECU connector
C-102 (terminal No. 28) and liftgate lock release handle
