Re: crv door locks Sign In

Do the doors unlock from the other door lock switches?

Re: crv door locks Sign In

Should be a door lock switch on the passenger door.

Does your key fob lock and unlock the doors?

Re: crv door locks Sign In

How do you get out from the passenger seat if the door is locked?

Re: crv door locks Sign In

Well, if the key fob can unlock and lock the doors that means the actuators and MCU (mutiplex control unit aka body control module) are functioning. The door lock switch doesn't actually go directly to the actuator. The switch is used to complete a circuit that sends a request to the MCU to lock and unlock the doors.

Your either going to need to get hold of a high end scan tool that can access the MCU to watch the door lock switch commands or your going to have to see if the switch is grounding the appropriate circuit when it is in the lock or unlock position with a DVOM (digital volt ohm meter). Your going to need a wiring schematic of the door lock system and a DVOM.

I don't understand why yours doesn't have a passenger door lock switch, because it is shown in the wiring diagram and location photos in the service information.

Re: crv door locks Sign In

Strange...... The wiring diagram shows a door lock switch on the passenger side.

Re: crv door locks Sign In

If you notice on the diagram you can ground the circuits at the door lock switch connector that comes from the MCU to send a request to unlock or lock the doors. If you have a good ground at the switch connector and grounding either circuit causes the locks to actuate, more than likely you have a switch fault.

Re: crv door locks Sign In

LMAO - sounds like my own family! Diagnose and fix it while they drive. Ever try to do a water pump with the engine running?

While here - see if a relay by the diagram Hammer posted shows the path and sometimes they don't let full power thru something and not enough for unlock but will lock? If key fob works it probably isn't that but spent hours on one (whole other vehicle) that was intermittent and took months to figure out as every time I touched it everything would just start working which messed up any diagnosisCrazy

Hard to fix what ain't broke in front of you,

Re: crv door locks Sign In

Remember you back probe with power to test light to check for ground. The actuator motors alternate between one being powered while the other wire gets power for one way and reverses it for the other way in general.

Probably already said that sometimes wires that bend thru the door jam with the most frequently used door (driver's usually) can fray to little current or break entirely unseen in a rubber cover. I do know locks take more effort to unlock (usually) than lock. Still this should be inconsistent if the key fob works?

Re: crv door locks Sign In

Can't answer that as there might have been an option package you don't have. Some - actually more all the time don't give you a key cylinder for passenger's side which to me stinks as sometimes here a car can be iced solid on one side and you don't have the other to use a plain key to get in if needed to warm the whole thing up to clear it off!

Cheap buzzards. What they do to save a buck,
