REMOVAL
CAUTION:

Do not drop or strike G sensor, because it has little endurance to impact.

Do not power tool etc., because G sensor is weak for the impact.
1. Remove center console. Refer to IP-14, "
(J) Center Console" , “INSTRUMENT PANEL ASSEMBLY”.
2. Disconnect G sensor harness connector.
3. Remove G sensor mounting bolts. Then remove yaw rate/side/
decel G sensor.
INSTALLATION
Installation is the reverse order of the removal.
CAUTION:
Do not drop or strike G sensor, because it has little endurance to impact.

ness connector M42 terminal 26 and ground with simple oscillo-
scope of CONSULT-II.
OK or NG
OK >> GO TO 3.
NG >>

If monitor indicates “0V” constantly, repair or replace malfunctioning parts after checking each
unit inputting vehicle speed signal (8 pulse), harness and connector between each unit and uni-
fied meter and A/C amp.

If monitor indicates “5V” or “12V” constantly, replace unified meter and A/C amp. Refer to DI-34,
"Removal and Installation of Unified Meter and A/C Amp." .
3. CHECK CONTINUITY BETWEEN COMBINATION METER AND UNIFIED METER AND A/C AMP.
1. Turn ignition switch OFF.
2. Disconnect combination meter connector and unified meter and A/C amp. connector.
3. Check continuity between combination meter harness connector
M70 terminal 20 and unified meter and A/C amp. harness con-
nector M42 terminal 26.
OK or NG
OK >> Replace combination meter.
NG >> Repair harness or connector.26 – Ground:NOTE:
Maximum voltage may be
12V due to specifications
(connected units).

8. CHECK VOLTAGE SIGNAL OF UNIFIED METER AND A/C AMP.
1. Turn ignition switch OFF and connect unified meter and A/C amp. connector.
2. Turn ignition switch ON.
3. Check voltage signal between combination meter harness con-
nector M70 terminal 19 and ground.
OK or NG
OK >> Replace combination meter.
NG >> Replace unified meter and A/C amp. Refer to DI-34, "
Removal and Installation of Unified Meter
and A/C Amp." .
