5. The method of operating the selector lever to individual posi- tions correctly should be as shown.
• (A): Press selector button to operate selector lever, while
depressing the brake pedal.
• (B): Press selector button to operate selector lever.
• (C): Selector lever can be operated without pressing selector
button.
6. Confirm the back-up lamps illuminate only when selector lever is placed in the “R” position. Confirm the back-up lamps do not illu-
minate when the selector lever is pushed toward the “R” position
side with the gear position remained in the “P” or “N” position.
7. Confirm the engine can only be started with the selector lever in the “P” and “N” positions.
8. Make sure transaxle is locked completely in “P” position. WCIA0620E

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 mu st make sure any dowels are installed correctly
during re-assembly.
• Improper alignment caused by missing dowels m ay 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-160 .
• After converter is installed to drive plate, ro tate crankshaft several turns to check that transaxle
rotates freely without binding.
• When installing the torque converter to the transaxle measure dis- tance A. WCIA0616E

TRANSAXLE ASSEMBLY
• When installing the cooler outlet tube (1) to the transaxle assembly (2), align the cooler tube bracket (A) against the transaxle as
shown.
• When installing the transaxle to the engine, align t he matching mark on the drive plate with the matching
mark on the torque converter alignment stud.
• When securing the transaxle to the engine, attach the bolts in
accordance with the following standard.
• When installing the drive plate to torque converter nuts, tighten them temporarily. Then tighten the nuts to the specified torque.
• After completing installation check for fluid level, fluid leakage, and the positions of CVT. Refer to CVT-196," Checking CVT Fluid " ,
CVT-345, " Adjustment of CVT Position " and
CVT-345, " Checking of CVT Position " .
• When replacing the CVT assembly, erase EEP ROM in TCM. Refer to CVT-190, " Service After Replacing
TCM and Transaxle Assembly " . WCIA0618E

CAN COMM CIRC [U1000] Malfunction is detected in CAN communication lines.
CAUTION:
Even when there is no malfunct ion on CAN communication system, mal-
function may be misinterpreted when battery has low voltage (when main-
taining 7 - 8 V for about 2 seconds) or 10A fuse [No. 14, located in the fuse
block (J/B)] is removed. DI-18VEHICLE SPEED CIRC [B2205]
Malfunction is detected when an erroneous speed signal is input.
CAUTION:
Even when there is no malfunction on speed signal system, malfunctions
may be misinterpreted when battery has low voltage (when maintaining 7
- 8 V for about 2 seconds). DI-15Display item [Unit]

Fuel Level Sensor Signal Inspection INFOID:0000000004307010
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.
