DTC P0745 LINE PRESSURE SOLENOID VALVEPFP:31940
DescriptionUCS005P7
The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in
response to signals sent from the TCM.
The line pressure duty cycle value is not constant when the closed throttle position switch is ON. To
confirm the line pressure duty cycle at low-pressure, the accelerator (throttle) should be open until the
closed throttle position switch is OFF.
CONSULT-II Reference ValueUCS005P8

DescriptionUCS005VM

The mechanical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, selector lever cannot be shifted from “P” position to any other posi-
tion unless brake pedal is depressed.
With the key removed, selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless selector lever is placed in “P” position.

The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside key cylinder, respectively.

from transaxle case while compressing spring retainer assem-
bly.
CAUTION:
Set SST directly over return springs.
5. Remove spring retainer assembly from transaxle case.
CAUTION:
Do not remove return springs from spring retainer.
6. Apply compressed air into the oil hole on transaxle case as
shown in the figure to raise piston while strongly pressing the
whole low & reverse brake piston by hand. When applying com-
pressed air, strongly press the whole piston and adjust the pres-
sure so that it is raised evenly. Portion (A) (low & reverse brake
pressure) especially tends to tilt.
CAUTION:
Apply air gradually and allow low & reverse brake piston to
come out evenly.
7. Remove low & reverse brake piston from transaxle case by turn-
ing it.
8. Inspect transaxle case. Replace if damaged or worn.

Revision: June 20062007 Versa
BCM (BODY CONTROL MODULE)PFP:284B2
System DescriptionEKS00I81
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 controlling the operation of various electrical components.
Also, it functions as an interface that receives signals 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.
