ASSEMBLY
m. Reinstall converter housing on transaxle case and ti ghten converter housing bolts to the specified torque.
Refer to AT-236, " Component " .
n. Insert Tool and measure turning torque of final drive assembly.
•Turn final drive assembly in both directions several times
to seat bearing rollers correctly.
• When old bearing is used again, turning torque will be
slightly less than the above.
• Make sure torque is close to the specified range.
REDUCTION PINION GEAR BEARING PRELOAD
1. Select proper thickness of reduction pinion gear adjusting shim using the following procedures.
a. Place reduction pinion gear on transaxle case as shown in the figure.
b. Install idler gear bearing outer race on transaxle case. Refer to AT-321, " Output Shaft, Output Gear, Idler Gear, Reduction Pin-
ion Gear and Bearing Retainer " .
c. Place idler gear bearing inner race on outer race.
d. Measure dimensions (B), (C) and (D), and calculate dimension (A).
• Measure dimension (B) between the end of reduction pinion gear and the surface of transaxle case.
• Measure dimension (B) in at least two places, and take the
average. Tool number : KV38105710 (J-39026)

BCM (BODY CONTROL MODULE)
System Description INFOID:0000000004306833
BCM (body control module) controls the operation of various electrical units installed on the vehicle.
BCM FUNCTION BCM has a combination switch reading function for reading the operation of combination switches (light, wiper,
washer, turn signal) in addition to the function for c ontrolling the operation of various electrical components.
Also, it functions as an interface that receives signal s from the front air control, and sends signals to ECM
using CAN communication.
COMBINATION SWITCH READING FUNCTION 1. Description • BCM reads combination switch (light, wiper) status , and controls various electrical components accord-
ing to the results.
• BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1-5)
and five input terminals (INPUT 1-5).
2. Operation description • BCM activates transistors of output terminals (OUTPUT 1-5) periodically and allows current to flow in
turn.
• If any (1 or more) of the switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input ter-
minals (INPUT 1-5) becomes active.
• At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When
voltage of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects
voltage change and BCM determines that switch is ON.
3. BCM - Operation table of combination switch • BCM reads operation status of combination switch by the combination shown in the following table.

Normal status
• When BCM is not in sleep status, OUTPUT te rminals (1-5) each turn ON-OFF every 10ms.
Sleep status
• When BCM is in sleep mode, transistors of OUTP UT 1 and 5 stop the output, and BCM enters low-cur-
rent-consumption mode. OUTPUTS (2, 3, and 4) turn ON-OFF at 60ms intervals, and receives lighting
switch input only.
CAN COMMUNICATION CONTROL CAN communication allows a high rate of information through the two communication lines (CAN-L, CAN-H)
connecting the various control units in the system. Each control unit transmits/receives data, but selectively
reads required data only.
BCM STATUS CONTROL BCM changes its status depending on the operation stat us in order to save power consumption.
1. CAN communication status • With ignition switch ON, CAN communicates with other control units normally.
• Control by BCM is being operated properly.
• When ignition switch is OFF, switching to sleep mode is possible.
• Even when ignition switch is OFF, if CAN co mmunication with IPDM E/R and combination meter is
active, CAN communication status is active.
2. Sleep transient status • This status shuts down CAN communication when ignition switch is turned OFF.
• It transmits sleep request signal to IPDM E/R and combination meter.
• Two seconds after CAN communication of all control units stops, CAN communication switches to inac-
tive status.
3. CAN communication inactive status • With ignition switch OFF, CAN communication is not active.
• With ignition switch OFF, control performed only by BCM is active.
• Three seconds after CAN communication of all cont rol units stops, CAN communication switches to
inactive status.
4. Sleep status • BCM is activated with low current consumption mode.
• CAN communication is not active.
