2. CHECK HARNESS CONTINUITY
1. Turn ignition switch OFF.
2. Disconnect multifunction switch (security indicator) connector.
3. Check voltage between multifunction switch (security indicator)
connector and ground.
OK or NG
OK >> Check the following.
Harness for open or short between BCM and multifunction switch (security indicator)
Security indicator lamp condition
NG >> Check the following.
15A fuse [No.37, located in fuse block (J/B)]

Self-diagnostic results:
“CHAIN OF ECM-IMMU” displayed on CONSULT-II screen
First perform the “SELF-DIAG RESULTS” in “BCM” with CONSULT-II, then perform the trouble diagno-
sis of malfunction system indicated “SELF-DIAG RESULTS” of “BCM”. Refer to BCS-15, "
CAN Com-
munication Inspection Using CONSULT-II (Self-Diagnosis)" .
1. CONFIRM SELF-DIAGNOSTIC RESULTS
Confirm SELF-DIAGNOSTIC RESULTS “CHAIN OF ECM-IMMU”
displayed on CONSULT-II screen.
NOTE:
In rare case, “CHAIN OF ECM-IMMU” might be stored during key
registration procedure, even if the system is not malfunctioning.
Is CONSULT-II screen displayed as shown in figure?
Yes >> GO TO 2.
No >> GO TO BL-271, "

Trouble DiagnosesNIS0020W
DIAGNOSTIC PROCEDURE
SYMPTOM: Transmitter does not activate receiver.
Before conducting the procedure given below, make sure that system receiver (garage door opener, etc.)
operates with original, hand-held transmitter. If NG, receiver or hand-held transmitter is malfunctioning, not
vehicle related.
1. ILLUMINATE CHECK
1. Turn ignition switch “OFF”.
2. Does red light (1) of transmitter illuminate when any transmitter
button (2) is pressed?
YES or NO
YES >> GO TO 2.
NO >> GO TO 3.
2. TRANSMITTER CHECK
Check transmitter with Tool*.
*:For details, refer to Technical Service Bulletin.
OK or NG
OK >> Receiver or hand-held transmitter malfunction, not vehicle related.
NG >> Replace auto anti-dazzling inside mirror (homelink universal transceiver).
3. CHECK POWER SUPPLY
1. Disconnect auto anti-dazzling inside mirror (homelink universal transceiver) connector.
2. Check voltage between auto anti-dazzling inside mirror (home
link universal transceiver) harness connector and ground.
OK or NG
OK >> GO TO 4.
NG >> Check the following.
10A fuse [No. 19 located in the fuse block (J/B)]
Harness for open or short between fuse and auto anti-dazzling inside mirror (homelink univer-
sal transceiver).
