Your door lock actuator have issues

Testimonial: "Thank you very much! Will try that!"

  • gregbundy70 Feb 24, 2012

    If it was an actuator would they unlock at all? Also if it was an actuator wouldn't the lock option not work? Does each door have its own actuator?

    Here is how it works battery voltage is supplied to the door lock relay at all times. When the front door lock switch is activated or switched a rod then activates the left front door lock also. The ETACM recieves the signal from the switch and power the rest of the door locks. Each of you door lock actuator uses a ground through a limit switch.In each of the appropraite door lock location.It is the ETACM de- energizes the relay when the door lock switches to the unlock position . Your front driver section affects the whole door locking and unlocking. One of the 2 front door lock actuator is offending. Start at the driver side.

SOURCE: transmission filter on 2003 hyundia santa fe

In 2002 they discontinued the external trans filter. So your vehicle could have the external filter. If you look next to the trans dipstick tube, on top of the trans case you will see the filter or you will see just a spot where the filter use to go before they eliminated it. Yes, the filter does llok like a regular engine oil filter. If the trans does not have the external filter ontop then there is no service to the filter to be done, the only recommendation is to bring vehicle into a shop to have the fluid flushed. By the way, make SURE you use the correct Hyundai SP-III trans fluid (not dexron/mercon). This fluid is specific to the Hyundai and can not be purchased from auto parts stores, only the dealership. Failure to use SP-III will cause premature wear to the internal bands and clutches.

It needs a new pruge valve. The purge valve is sticking open allowing fuel vapors into the intake manifold causing a rich hard start condition.

Yes. Your Local Auto Parts Store should Carry these as Direct Replacements. If Not, Sears Carries them.

2004 Hyundai Santa Fe. Key fob only works if the ignition switch is in the On position. How to troubleshoot and fix.

The key fob does two things quite separately. It open and closes the doors. It also provides the correct security credentials to the vehicle immobilizer. At first is sounded like whomever programmed it only did half the job. It may also be that the internal battery is low. It is a complex error with the vehicle computer systems on a key fob with unknown history and issues.

Or go into a place that does car alarms and radios. They will have the necessary test equipment and scan tool computers.

4x4 diesel. Why can't doors be unlocked or locked?

their is a way to do it but recheck battery first sometimes the relearn process doesnt work or the fob itself is dead also if auto /remote start will need dealer to flash fob ---- 2002 santa fe and followed programming instructions and eventually was able to program the new remote. But, I did not realize I had to program my existing remote at the same time. Since, I have retried programming both remotes many times with no success--the new one works, but the old one won't. The instructions were: 1) Locate switch under dash, behind fuse box; 2) Turn ignition switch on, but don't start engine; 3) Wait 5 seconds, set memory switch to SET position; 4) Press remote LOCK button; press second remote transmitter LOCK button; 5) Set memory switch to OFF; 6) Switch ignition OFF. 7) Confirm programming by locking and unlocking vehicle.

I have a 2003 Hyundai sante fe that will not start and I believe it may be related to the security system. This has happened twice, but the first time I got the car to start after clicking lock/unlock

Hi try operating with the spare remote to lock & unlock the doors & try the spare key to start may be the immobilizer playing up if it starts with the spare key it could be the transponder in the key itself wanting re programing
hope this helps

2003 Monte Carlo SS, FOBS won't unlock doors (new batterries), use key and open the door with the door open FOB will lock and unlock the door, shut the door and the FOB won't lock the doors. After...

If the passkey is messed up, there will be a light on the dash that says security, or have a picture of a car with a lock thru it. If there is no light when the key is turned forward, then its NOT a passkey problem.

Buy 2002 Santa Fe Nov 16, couldn't unlock doors to

i had a problem not unlike this in my santa fe 1.9td uk spec.
my car had been sitting for a few months and when i returned to drive it again the same problem came to light.
i also rep[lsaced the key fob.
it could be one of two things.
firstly the systen might neen re-set. if you disconnect the battery for 2 hours then attach ti again it might work.
if this fails it might be the actuator in one of the doors. if it is faulty then it only semi closes the lock, but it then thinks that has to lock again. and locks the door.
hope this helps.

Hyundai santa fe 2002 remote key fob locking ok but fails to unlock. suspect micro switch faulty. can it be replaced?

Do the doors lock normally when using the manual switch on the dirver's door panel? If so, the problem is in the ETACS module. Here's the wiring diagram:

Central locking wont stay open

Here's what I suspect is happening. The door locks will lock and unlock normally when the key is OUT of the ignition. If the key is IN the ignition, the doors cannot be locked (manually, key fob, or otherwise, if the system is operating as designed - prevents the doors being locked when the key is in the ignition). I've seen this problem before, but on a Santa Fe, not an Accent. The ground signal of the right hand front passenger door was lost, and the doors automatically locked. Perhaps something similar is happening in the circuit between the ETACS module and the right front passenger door lock/unlock actuator. Could be anywhere in the circuit.
