Car will not start

Good afternoon,

Did the alarm stop going off? How did you disarm it?

With Toyota, lock and unlock the driver's door and try it.

If that does not work, Open and close the trunk.

They were 2 common places to disarm the system.

How did you disarm the alarm?

Roy

That did not disarm it. It just turned off the horn.

Did you try locking and unlocking the door?

Roy

Current always flows to TERMINAL B-9 of the Theft Deterrent and door lock control ECU through the DOOR Fuse, and to TERMINAL A-1 through the DOME fuse.

When the Ignition SW is turned ON, the current flowing through the ECU-IG fuse --> TERMINAL B-7 of the ECU --> B-6 flows through the coil side of the power main relay to GROUND, causing the relay to operate. The current flowing through the power CB DOOR fuse flows to the door lock control switches, causing the indicator light to light up.

1. MANUAL LOCK OPERATION
When the door lock control SW or door key lock and Unlock SW are pushed to LOCK position, a lock signal is input to TERMINAL A-5, A-22 (for key SW) of the Theft Deterrent and door lock control ECU and causes the ECU to function. Current flows from TERMINAL B-9 of the ECU --> TERMINAL B-3 --> TERMINAL 4 of the door lock motors --> TERMINAL 2 -- TERMINAL B-5 (Front LH), B-2 (the other) of the ECU --> TERMINAL B-4 --> GROUND and the door lock motor causes the door to lock.

2. MANUAL UNLOCK OPERATION
When the door lock control SW or door key lock and Unlock SW are pushed to UNLOCK position, an unlock signal is input to TERMINAL A-8, A-6 (for key SW LH) or A-16 (for key SW RH) of the Theft Deterrent and door lock control ECU and causes to function. Current flows from TERMINAL B-9 of the ECU --> TERMINAL B-5 (Front LH), B-2 (the other) --> TERMINAL 2 of the door lock motors --> TERMINAL 4 --> TERMINAL B-3 of the ECU --> TERMINAL B-4 -- GROUND and the door lock motor causes the door to unlock.

When unlock operation occurs using the LH door key lock and Unlock SW, performing the unlock operation once unlocks only the driver's door. To unlock all the other doors together, unlock operation must be performed again within 3 seconds of the first operation.

3. IGNITION KEY REMINDER OPERATION
Operation of door lock button (operation of door lock motors)
When the Ignition key is in the cylinder (unlock warning SW ON) and the door is opened and locked using door lock button (door lock motor), the door is locked once but each door is unlocked soon by the operation of the ECU. As a result of ECU activation, the current flows from TERMINAL B-9 of the ECU --> TERMINAL B-5 (Front LH), B-2 (the other) --> TERMINAL 2 of the door lock motors --> TERMINAL 4 --> TERMINAL B-3 of the ECU --> TERMINAL B-4 --> GROUND and causes all the door lock control SW and door lock key SW.

Key Less Lock Operation
When the Ignition key is still inserted in the cylinder (unlock warning SW ON), the door is open and unlock operation is prevented by keeping the door lock button pressed to the lock side, the door is kept in the lock condition. If the door is then closed, a signal is input to the ECU from the door courtesy SW. This activates the ECU and each door is unlocked.
