with oscilloscope when
power window is in auto-
matic closing operation.
If check result is NG,
replace power window
regulator motor (front
driver side).
If check result is OK,
replace power window
main switch.
RESET LIMIT SWITCH
Reset limit switch. Refer to BT section.
Then check voltage between power win-
dow main switch terminal
V9and ground
during power window closing operation at
least ten times.
OK
cNG
Replace power window
regulator motor (front
driver side).

CHECK IN*NOTE: In rare case, ªCHAIN OF ECM-IMMUº might be stored as a self-
diagnostic result during key registration procedure, even if the sys-
tem is not malfunctioning.
Listen to customer complaints or request. (Get symptoms)
NOTE:
If customer reports a ªNo startº condition, request ALL
KEYS to be brought to the Dealer in case of a NATS mal-
function.
TROUBLEKEY SERVICE REQUEST (Additional key ID registration).Verify the security indicator.INITIALIZATION
(Refer to CONSULT-II operation
manual NATS.)
cUsing the CONSULT-II program card for NATS check the
ªSELF-DIAG RESULTSº with CONSULT-II.b
Self-diagnostic results referring to NATS, but no information
about engine self-diagnostic results is displayed on CONSULT-
II.Self-diagnostic results referring to NATS and ªDON'T ERASE
BEFORE CHECKING ENG DIAGº are displayed on CONSULT-
II.
(This means that engine trouble data has been detected in
ECM.)
Turn ignition switch ªOFFº.
Repair NATS.
(If necessary, carry out ªC/U INITIALIZATIONº with CONSULT-
II.*)Turn ignition switch ªOFFº.
Turn ignition switch ªONº.Repair NATS according to self-diagnostic results referring to
NATS.
(If necessary, carry out ªC/U INITIALIZATIONº with CONSULT-
II.*)
Erase the NATS ªSELF-DIAG RESULTSº by using CONSULT-II.
(Touch ªERASEº)Do not erase the NATS ªSELF-DIAG RESULTSº by using
CONSULT-II.
Start the engine.Check the engine ªSELF-DIAG RESULTSº with CONSULT-II by
using the CONSULT-II generic program card.
(Engine diagnostic software included)b
NGVerify no lighting up of the security indicator.
OKRepair engine control system (Refer to EC section.) when self-
diagnostic results except ªNATS MALFUNCTIONº are detected.
When only ªNATS MALFUNCTIONº is detected, erase the self-
diagnostic results and go to the next step.
CHECK OUTStart the engine. Does the engine start properly?
OKNG
Perform running test with CONSULT-II in engine ªSELF-DIAG
RESULTSº mode.Erase the NATS and engine ªSELF-DIAG RESULTSº by using
the CONSULT-II program card for NATS and generic program
card.
NGVerify ªNO DTCº displayed on the CONSULT-II screen.
