Adjustment of CVT PositionINFOID:0000000001703682
CAUTION:
Make sure that parking brake is applied before adjustment.
1. Loosen the control cable nut (A) and place the manual lever (1)
in “P” position.
2. Place selector lever in “P” position.
3. Push the control cable (2) in with a load of 9.8 N (approximately
1 kg, 2.2 lb). Release the control cable and temporarily tighten
the control cable nut.
NOTE:
Do not move the manual lever. Make sure the manual lever
stays in the “P” position.
4. Tighten the control cable nut.
CAUTION:
Secure the manual lever when tightening nut.
5. Check the operation of the CVT. Refer to CVT-171, "
Checking of CVT Position".
Checking of CVT PositionINFOID:0000000001703683
1. Place selector lever in “P” position, and turn ignition switch ON. (Do not start engine.)
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check that the actual position of the selector lever matches the position shown by the shift
position indicator and the manual lever on the transaxle.

UNIFIED METER CONTROL UNIT
• Speedometer, odo/trip meter, tachometer and fuel gauge are controlled by the unified meter control unit,
which is built into the combination meter.
• Warning and indicator lamps are controlled by signals drawn from the CAN communication system, BCM
(body control module), and components connected directly to the combination meter.
• Odo/trip meter and A/T indicator (with A/T) or CVT indicator (with CVT) segments can be checked in self-
diagnosis mode.
• Meters/gauges can be checked in self-diagnosis mode.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
• through 10A fuse [No. 13, located in the fuse block (J/B)]
• to combination meter terminal 27.
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 28.
Ground is supplied
• to combination meter terminals 21, 22 and 23
• through grounds M57 and M61.

Self-Diagnosis Mode of Combination MeterINFOID:0000000001704497
SELF-DIAGNOSIS MODE FUNCTION
• Self-diagnosis can check for continuity between meter control circuit and each meter (speedometer, tachom-
eter and fuel gauge).
• Self-diagnosis can check for odo/trip meter and A/T indicator (with A/T) or CVT indicator (with CVT) seg-
ment, low-fuel level warning lamp, low water temperature indicator lamp, and high water temperature warn-
ing lamp.
OPERATION PROCEDURE
1. Turn the ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.
