2. Disconnect the primary speed sensor (A) and the secondary
speed sensor connector (B) and CVT unit connector (C). Refer
to CVT-9, "
Removal and Installation Procedure for CVT Unit
Connector".
3. Remove the harness from the transaxle.
4. Remove the four drive plate to torque converter nuts. NOTE:
Rotate the crankshaft clockwise as viewed from front of engine
for access to drive plate to torque converter nuts.
5. Put matching marks on the drive plate and torque converter alignment stud. CAUTION:
For matching marks, use paint. Never dama ge the drive plate or torque converter.
6. Remove the transaxle to engine and engine to transaxle bolts.
7. Separate the transaxle from the engine.
8. If necessary, remove the following from the transaxle: • CVT fluid charging pipe
• Engine mounting bracket (LH)
• Fluid cooler tubes
• Air breather hose
• Any necessary brackets
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• When replacing an engine or transmission you must make sure any dowels are installed correctlyduring re-assembly.
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive train components.
• Do not reuse O-rings and copper washers.
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the nuts for the torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-159
.
• After converter is installed to drive plate, ro tate crankshaft several turns to check that transaxle
rotates freely without binding.

Self-Diagnosis Mode of Combination MeterINFOID:0000000005929166
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 indi cator (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

Fuel Level Sensor Signal InspectionINFOID:0000000005929173
Symptom:• Improper fuel gauge indication.
• Low-fuel warning lamp indication is irregular.
NOTE:
The following symptoms do not indicate a malfunction.
• Depending on vehicle position or driving circumstance, the fuel level in the tank shifts and the indication may fluctuate.
• If the vehicle is fueled with the ignition switch ON, the indication will update slowly.
• If the vehicle is tilted when the ignition switch is turned ON, fuel in the tank may flow to one direction result-
ing in a change of reading.

A/T INDICATOR
A/T INDICATOR
System DescriptionINFOID:0000000005929184
The TCM receives A/T indicator signals from the transmission range switch (R-range, D-range, 2-range and 1-
range) and the combination meter (P-range and N-range). The TCM then sends A/T position indicator signals
to the combination meter via CAN communication lines. The combination meter indicates the received shift
position.
