ECU Resetting


While performing the procedures below, ensue that you are respecting the times stated. If the steps are not done within the specified times, the module will not reset. You will need to use a watch or a chronograph while performing the procedures.

8. Turn the ignition switch to “OFF” position and start the vehicle. If procedure has been done correctly, then the light light will turn off.
If the light continues to stay on, repeat the procedure.

Accelerator Pedal Release Position Learning

Procedure

1. Ensure that the accelerator pedal is completely released before starting the procedure.
2. Turn the ignition switch “ON” and wait at least 2 seconds.
3. Turn the ignition switch “OFF”, and wait at least 10 seconds.

2. Turn ignition switch to the “ON” position.
3. Turn ignition switch to the “OFF” position and wait at least 10 seconds.
Ensure that the throttle valve moves after turning the switch off.

Idle Air Volume Learning (Throttle Position Learning)

Procedure

1. Follow the Accelerator Pedal Released Position Learning described above.
2. Do the Throttle Valve Closed Position Learning also described above.
3. Start the engine, and allow warming up.
4. Turn the ignition on “OFF” positionand wait 10 seconds.
5. Ensure that accelerator pedal is fully released, then turn the ignition switch to “ON” position, and wait 3 seconds.
6. Repeat the steps a and b below five times within 5 seconds in sequence.

How to relearn throttle body on a Lexus is250


Pedal Relearn Procedure
Accerlerator Pedal Released Postion Learning is and operation to learnicon1.png the full released postions of the accerlerator pedal by monitoring the accelerator pedal sensor output signal. It must be performed each time harness connector of accelearator pedal postion sensor or ECM is disconnected.

1. Make Sure the acceleartor Pedal is fully released
2. Turn Ignition switchON and wait at least 2 Seconds.
3. Turn ignition switchOFF and wait at least 10 Seconds
4. Turn Ignition switchON and wait at least 2 seconds.
5. Turn Ignition switchoff and wait at least 10 seconds

Throttle Valve Relearn
Throttle ValveClosed Postion Learningicon1.png is to learn the fully closed postion of the throttle valveby monitoring the throttle position sensor output signal. It must be performed each time harness of
electric throttle control actuator or ECM is disconnect.

1.Make sure accelerator pedal is fully released.
2. Turn ignition ON
3. Turn igntion switch OFF and wait at least 10 seconds. Make sure that the throttle valvemoves during the 10 seconds by confrming the operating sound.
(You can hear the TB sound when you have key on and shifter in first gear and step on the gas. So you know what you listening for.)


Idle Air Volume Relearn Procedure
The Following Condtions Must be met in order for procedure to Work.

Battery Voltage :More than 12.9 volts at idle
Engine Coolant Temp 158-203 degrees Farenhiet
Electric Load Switch OFF i.e Air Condition, headlamps , rear defogger
Steering Wheel: Neutral Postion (Straight Ahead)
PNP Switch: OFF (Park Neutral Switch i.e. Clutch Switch...pretty sure)


1. Perform ACCERLEARATOR PEDAL RELEASED POSTIONS LEARNING
2. Perform THROTTLE VALVECLOSED POSITION LEARNING
3. Start engine and warm it up to operation temperature
4. Turn igniton switch OFF and wait at least 10 seconds
5. Confirm Gas Pedalif fully realeased, then turn igniton switch ON and wait 3 seconds
6. Fully step on and release gas pedal5 time within 5 seconds
8. Wait 7 seconds and fully step on gas and stay on until MIL stops blinking and is steady.

Put on new fuel pump got pressuer but want stay cranked


Your post is lacking any detail. However, if you are stating that the engine starts after being cranked but dies out (wont stay running) there are 2 ways the fuel pump is activated. When the key is first turned on, there is a 5 second fuel pump run (the ECM energizes the fuel pump relay). After the engine starts, the fuel pump relay will only stay energized when the oil pressure switch closes keeping the fuel pump relay on (oil pressure is above 5-7 psi). If the oil pressure switch is faulty or there is no oil pressure, the engine will stall just after starting.

How can I stop airbag warning light flashing continuously on my Nissan Tiida


Try this:
5. If “AIR BAG” warning lamp operates as [as I said before], turn ignition switch “OFF” to reset from Diagnosis mode
1. Turn ignition switch “ON”.
2. After “AIR BAG” warning lamp lights for 7 seconds, [i.e. when it stops running solid and starts flashing] turn ignition switch “OFF” within 1 second. [DO NOT SWITCH IT TO LOCK, SWITCH IT TO ACC]
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 two times. (Perform 3 times in total.)
5. Turn ignition switch “ON”.
SRS is now in Diagnosis mode.
Try it a few times. If you can't get it to work, have someone else try. If you STILL can't get it to work, check your battery voltage. It might be low.
In diagnosis mode, you're going to hope the light flashes slowly. 2 seconds off, 3 seconds on, and repeats. If your light does this, this means that the computer detected a previous error that hasn't been erased. This is good.
to User mode and to erase the memory of the malfunction.
6. Turn ignition switch “ON”. “AIR BAG” warning lamp operates in
User mode. [it should stay on for 7 seconds, then go off, like normal.]

Cruise control out


I have the same issue. A mechanic told me that it's either a faulty switch (junkyard cheap) or a faulty ground wire in the steering column (mechanic expensive). Regardless, and I know this sounds a bit "ghetto", but I wedged a dime in between the button and the switch casing and the cruise stays on without issue. From everything I read, the steering column is a big no no due to the airbag. To me, problem solved for a dime. Cheapest fix ever. Hope it works for you.
