P1604 startabili

P1604 TOYOTA - Startability Malfunction
Repair Importance Level: 3/3
Repair Difficulty Level: 3/3

Possible causes
Low Battery charge
Starting system
Low quality fuel
Clogged Fuel filter
Faulty Engine Control Module (ECM)

It has to be programmed .
Remote Transmitter Programming NOTE: All remote transmitters are programmable and must be set at the same time.

1. Turn the key from OFF to RUN four times within three seconds, ending in RUN. The locks will then lock and unlock, confirming program mode has been entered.

1. Press any button on each remote transmitter to be programmed. The doors will lock and unlock to confirm that each remote transmitter has been programmed.

1. If additonal remote transmitters are to be programmed, repeat Step 3 within 7.5 seconds or steps 2 and 3 if more than 7.5 seconds have elapsed.

1. To exit program mode, turn the ignition to START or wait 7.5 seconds.

1. NOTE: Failure to wait at least 20 seconds will cause programming failures.
   Wait at least 20 seconds after turning the key to OFF or after the last remote transmitter has been programmed to activate a remote transmitter for testing or verification.

Transmitter Programming
Important: Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle. The order in which the transmitters are programmed is important. The first transmitter programmed will be transmitter #1, and the second transmitter programmed will be transmitter #2. Use care to program the transmitters correctly.
The scan tool must stay connected until all of the transmitters are programmed.

Invalidate All
This procedure will erase all keyless entry transmitters from memory.
Install a scan tool.
Turn ON the ignition with the engine OFF.
With the scan tool, select Body.
Select Remote Control Door Lock Receiver (RCDLR).
Select Module Setup.
Select Program Key Fobs.
Select Invalidate All Fobs.
Follow the scan tool on screen instructions.
Transmitter Slot Programming
Transmitter slot programming allows a single transmitter to be programmed into a specific slot without affecting any of the other programmed transmitters. By using slot programming, the transmitter originally programmed to a specific slot is erased and the new transmitter learned in its placed.
Install a scan tool.
Turn ON the ignition with the engine OFF.
With the scan tool, select Body.
Select Remote Control Door Lock Receiver (RCDLR).
Select Module Setup.
Select Program Key Fobs.
Select the key fob desired to be programmed.
Follow the scan tool on screen instructions.
Remove the scan tool.
Exit the vehicle. Operate all functions on transmitters to verify correct system operation.

For a Toyota, it indicates a startability problem, it is a very vague diagnostic troubleshoot code and therefore not component specific.

Components to check, Crank Shaft Position sensor, Spark Plugs, MAF sensor, fuel pump... etc.

code p1604 refers to starting system --malfunction===causes--wiring---connections--vacuum leaks--MAF sensor--ignition system--engine coolant temperature sensor--fuel supply system--throttle body--variable valve timing system---A/C system--- power steering control control--- ECM
Try to think back to the symptoms before the engine failed to start
were you in snow, did it get hot, was it lagging in high rpms,
did it just stop or was it misfiring
each symptom will point to an item in the list of causes.

TRANSMITTER PROGRAMMING
IMPORTANT: All transmitters which are to be recognized by the remote control door
lock receiver (RCDLR) must be programmed in a single programming
sequence. If the system is placed in program mode it will erase all
previously programmed transmitters upon the receipt of the
programming signal from the first transmitter. Up to 4 transmitters can
be programmed. Do not operate or program the transmitters in the
vicinity of other vehicles that are in the keyless entry program mode.
This prevents the programming of the transmitters to the incorrect
vehicle.
Install 1. a scan tool.
Use the scan tool in order to access the Body Control Module (BCM) Special Function or
Module Setup: Program Key Fobs.
2.
3. Press the START soft key on the scan tool.
IMPORTANT: The scan tool must stay connected until all of the transmitters are
programmed.
Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter.
After a delay of 5-10 seconds, the scan tool will indicate that the transmitter is programmed.
4.
5. Repeat the previous step in order to program up to 4 transmitters.
6. Remove the scan tool.
7. Operate the transmitter functions in order to verify correct system operation.

fco.lozano, mi carro cirrus 2005 lxi turbo 2.4 triptoni, a veces no entra la tercera c bloquea y nada mas entra segunda lo apago cuando ya esta medio frio lo enciendo y entran bien las velocidades pero c vuelve a calentar pasa lo mismo kien me puede ayudar xfa. gracias

You must have all remote entry transmitters (maximum of four) available before beginning this procedure. According with the Mariner Owners Manual check this procedure to reprogram the remote entry transmitters:

1. Ensure the vehicle is electronically unlocked.
2. Put the key in the ignition.
3. Turn the key from the 1 (LOCK) position to 3 (RUN).
4. Cycle eight times rapidly (within 10 seconds) between the 1 (LOCK) position and 3 (RUN).
Note: The eighth turn must end in the 3 (RUN) position.
5. The doors will lock, then unlock, to confirm that the programming mode has been activated.
6. Within 20 seconds press any button on the remote entry transmitter.
Note: If more than 20 seconds have passed you will need to start the procedure over again.
7. The doors will lock, then unlock, to confirm that this remote entry transmitter has been programmed.
8. Repeat Step 6 to program each additional remote entry transmitter.
9. Turn the ignition to the 1 (LOCK) position after you have finished programming all of the remote entry transmitters.
10. The doors will lock, then unlock, to confirm that the programming mode has been exited.

Note: If all remote entry transmitters are not present during the programming procedure, the missing transmitters will not work with the vehicle following programming.

Hope helps.

does trunk button work? panic button?
here's 2003 info:

• The doors do not lock/unlock using the remote transmitter

• Remote transmitter.
• Driver door module (DDM).

• Go To Pinpoint Test G .

SECTION 501-14: Handles, Locks, Latches and Entry Systems 2003 Town Car Workshop Manual
GENERAL PROCEDURES Remote Transmitter Programming

1. Cycle the ignition from OFF to RUN four times within three seconds. The locks will then lock and unlock, confirming that the program mode has been entered.

1. NOTE: When the first keyless entry remote transmitter is programmed, all other keyless entry remote transmitters are erased.
   Press any button on the transmitter to be programmed.

1. If additional keyless entry remote transmitters are to be programmed, repeat Step 2 within 7.5 seconds.
