INTEGRATED HOMELINK TRANSMITTER
Revision: 2006 January2006 M35/M45
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).

COMBINATION METERSPFP:24814
System DescriptionNKS003TV
UNIFIED METER CONTROL UNIT
Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter. Unified meter control unit receives sig-
nals from unified meter and A/C amp.
Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.
Digital meter is adopted for odo/trip meter.
NOTE:
The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
Dot matrix LCD is adopted to display “push engine starter”, “A/T position” and “ICC system* ”.
Odo/trip meter and dot matrix LCD segments can be checked in self-diagnosis mode.
Meters/gauges can be checked in self-diagnosis mode.
*: With ICC system
UNIFIED METER AND A/C AMP.
Refer to DI-28, "COMBINATION METER CONTROL FUNCTION" in “UNIFIED METER AND A/C AMP”.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
through 10A fuse [No. 21, located in the fuse block (J/B)]
to combination meter terminal 23,
through 10A fuse [No. 19, located in the fuse block (J/B)]
to unified meter and A/C amp. terminal 54.
With the ignition switch in the ACC or ON position, power is supplied
through 10A fuse [No. 6, located in the fuse block (J/B)],
to combination meter terminal 2, and
to unified meter and A/C amp. terminal 41.
With the ignition switch in the ON or START position, power is supplied
through 10A fuse [No. 14, located in the fuse block (J/B)]
to combination meter terminal 12,
through 10A fuse [No. 12, located in the fuse block (J/B)]
to unified meter and A/C amp. terminal 53.
Ground is supplied
to combination meter terminals 9, 10 and 11
to unified meter and A/C amp. terminals 55 and 71
through grounds M16 and M70.
