2001 TOYOTA PRIUS fuse

2001 PRIUS (EWD414U)
When the ignition SW is turned to ACC position the current from the ACC fuse flows to TERMINAL 1 of the shift lock ECU, in
the ON position, the current from the ECU±IG fuse flows to TERMINAL 3 of the ECU.
1. SHIFT LOCK MECHANISM
With the ignition SW on, when a signal that the brake pedal is depressed (Stop light SW on) and a signal that the shift lever
is put in P position (Continuity between P1 and P of the shift lock control SW) is input to the ECU, the ECU operates and
current flows from TERMINAL 3 of the ECU to TERMINAL SLS+ of the shift lock solenoid to solenoid to TERMINAL SLS± to
TERMINAL 5 of the ECU to GROUND. This causes the shift lock solenoid to turn on (Plate stopper disengages) and the shift
lever can shift into position other than the P.
2. KEY INTERLOCK MECHANISM
With the ignition SW ON or ACC position, when the shift lever is put in P position (No continuity between P2 and P of shift
lock control SW), the current flowing from TERMINAL 4 of the ECU to the key interlock solenoid is cut off. This causes the
key interlock solenoid to turn off (Lock lever disengages from LOCK position) and the ignition key can be turned from ACC to
LOCK position.

DOOR LOCK CONTROL
The current is always sent from DOOR fuse to TERMINAL B of body ECU. When ignition SW is turned on, the current is sent
from GAUGE fuse to TERMINAL IG of the body ECU.
1. MANUAL LOCK OPERATION
When the door lock control SW (Power window master SW) is turned to LOCK position, the lock signal from TERMINAL
MPX1 of power window master SW is input to TERMINAL RX of body ECU to operate ECU. The current is sent from
TERMINAL ACT+ of ECU to each motor and the motor locks the doors by the current sent from TERMINAL ACT± of ECU to
GROUND.
2. MANUAL UNLOCK OPERATION
When the door lock control SW (Power window master SW) is turned to UNLOCK position, the unlock signal from
TERMINAL MPX1 of power window master SW is input to TERMINAL RX of body ECU to operate ECU. The current is sent
from TERMINAL ACT± of ECU to each motor and the motor unlocks the doors by the current sent from TERMINAL ACT+ of
ECU to GROUND.
3. DOOR KEY LOCK AND UNLOCK OPERATION
*Lock operation from the driver's side door
When the driver's side door is locked using the ignition key, all the doors are locked.
*Unlock operation from the driver's side door
When the driver's side door is unlocked once using the ignition key, only the driver's side door is unlocked. If this operation
is repeated within 3 seconds, all the other doors are unlocked.
*Lock operation from the front passenger's side door
When the front passenger's side door is locked using the ignition key, all the doors are locked.
*Unlock operation from the front passenger's side door
When the front passenger's side door is unlocked using the ignition key, all the doors are unlocked

WIRELESS DOOR LOCK CONTROL
The current is always sent from DOOR fuse to TERMINAL B of body ECU. At the same time, the current is always sent from
DOME fuse to TERMINAL CPUB of power window master SW, and from ECU±B fuse to wireless door lock receiver. When
ignition SW is turned on, the current is sent from GAUGE fuse to TERMINAL IG of body ECU.
1. WIRELESS DOOR LOCK OR UNLOCK NORMAL OPERATION
*Lock operation
When the LOCK SW of the transmitter is pushed, all the doors are locked.
*Unlock operation
When the UNLOCK SW of the transmitter is pushed, all the doors are unlocked.
2. AUTOMATIC LOCK OPERATION
After all the doors are unlocked by pushing the UNLOCK SW of the transmitter, unless each of the doors is opened or the
ignition key is inserted, all the doors are locked again.
3. VISUAL CONFIRMATION OF LOCK OR UNLOCK FUNCTION
When doors are locked by using the transmitter, the taillight and parking lights blink once. When doors are unlocked by using
the transmitter, the taillights and parking lights blink twice. If UNLOCK SW of the transmitter is pushed while all the doors are
locked, doors are unlocked and the room lights are turned on simultaneously.
4. WIRELESS CONTROL STOP FUNCTION
If the following situations occur, wireless door lock function does not operate.
*When each of the doors opens. (Door courtesy SW is on)
*When ignition key is inserted to ignition SW. (Unlock warning SW is on)
*When ignition SW is on.
5. REPEAT FUNCTION
If the doors are not locked after the lock signal is out put from transmitter by pushing LOCK SW, the lock signal is sent again
to lock the doors.
6. PANIC MODE FUNCTION
When the panic SW of the transmitter is pushed, the horn comes on, and the headlight and taillight flashes.

SRS
The SRS is a driver and front passenger protection device which has a supplemental role to the seat belts.
When the ignition SW is turned to ACC or ON, current from the SRS ACC fuse flows to TERMINAL (B) 6 of the airbag sensor
assembly. Only when the ignition SW is on does the current flow TERMINAL (B) 5 of the airbag sensor assembly.
If an accident occurs while driving, when the frontal impact exceeds a set level, current flows to TERMINALS (B) 14, (B) 10,
(A) 2 and (C) 5 of the airbag sensor assembly to TERMINAL 1 of the airbag squibs and the pretensioners to TERMINAL 2 to
TERMINALS (B) 13, (B) 11, (A) 1 and (C) 6 of the airbag sensor assembly to TERMINAL (B) 27, (B) 28 or BODY GROUND
to GROUND, so that current flows to the front airbag squibs and the pretensioners and causes them to operate.
When the side impact also exceeds a set level, current from the ignition SW (IG2) or SRS ACC fuse flows to TERMINALS
(A) 5, (C) 2, (A) 2 and (C) 5 of the airbag sensor assembly to TERMINAL 1 of the side airbag squibs and the pretensioners to
TERMINAL 2 to TERMINALS (A) 6, (C) 1, (A) 1 and (C) 6 of the airbag sensor assembly to TERMINAL (B) 27, (B) 28 or
BODY GROUND to GROUND, causing side airbag squibs and the pretensioners to operate.
The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.
The airbag stored inside the passenger's instrument panel is instantaneously expanded to soften the shock to the front
passenger.
Side airbags are instantaneously expanded to soften the shock of side to the driver and front passenger (w/ side airbags).
The pretensioners make sure of the seat belt restrainability.
