operates with original, hand-held transmitter. If NG, receiver or hand-held transmitter is malfunctioning, not
vehicle related.
1. CHECK ILLUMINATION
1. Turn ignition switch “OFF”.
2. Does red light (LED) of transmitter illuminate when any transmit- ter button is pressed?
YES or NO
YES >> GO TO 2.
NO >> GO TO 3.
2. CHECK TRANSMITTER
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 inside mirror assembly.
3. CHECK BCM OUTPUT POWER SUPPLY
Does room lamp come on when driver side door opened. Refer to LT- 1 5 2
.
Does room lamp illumination?
YES >> GO TO 4.
NO >> Repair or replace the malfunction part.
4. CHECK POWER SUPPLY
1. Disconnect transmitter connector.
2. Turn ignition switch “OFF”.
3. Check voltage between auto anti-dazzling inside mirror (homelink universal transceiver) connector R4 terminal 10 (B/W)
and ground.
OK or NG
OK >> GO TO 5.
NG >> Repair or replace harness between BCM and anti-daz-
zling inside mirror (homelink universal transceiver).
