we recently replaced the drivers door latch assembly with actuator- - the rear L H door still wont lock & unlock by the key IDEAS?

 

Might try another " Hard Reset " as you may have hooked up the new fwd latch with the battery connected , the security ECU saw the fwd switch and got out of normal sequence effecting the aft .

 

You said "still won't.." So the LH rear wouldn't actuate...and you replaced the RH Front?
I'm assuming the driver's door likewise wouldn't behave. It is entirely possible both failed, though unlikely to have happened at the exact same time.

Further, "..with the key." Does it (LH rear) work with the FOB or the button on the dash?

 

hard reset- remind me how to hard reset- please

 

the drivers door stuck locked - all other doors were ok - mechanic got door opened thru door panel & set it so we could use key to lock & unlock drivers door . The rear LH door then wouldn't lock & unlock with key from that point - and the trunk button stopped working & the inside trunk courtesy lights stopped also . Yesterday mechanic replaced drivers door assembly w actuator and all doors work correctly except rear LH. still will not work with key .I know Jags can be quirky so I wonder if I can do a hard reset like Penelope suggested - I forget how to do that ?

 

To reset the hiccup in the module if it is the case there is a Jaguar " Hart Reset " of the car that reboots like in a PC . In the steps :

1. Remove car stereo to prevent anti- theft system from activating
2. Ensure battery is fully charged
3. Key to the on position , not start
4. Remove both battery terminals and connect with a jumper clip or hold to each other for a period of time , the longer the better ( this will not short the battery or fry the cars electronics )
5. Reconnect battery post with key still in the on position .
6. Rotate key back to off

Your engine may run rough for a while as the engine ECU relearns some perimeters of engine regulation .

 

I'm not comfortable holding cables together as in American cars - can blow battery up - maybe I will take to jag dealer ? will they know hard reset I assume?

 

also for the bonnet courtesy lamps & trunk outside button release= no fuses are blown so could they be connected to replaced door actuator ? maybe its defective as a used part?

 

When you remove both cables from the battery you electrically isolate it from harm . You can wait to hear from others if it is a concern . Apart from a reset what you have to be concerned about if you physically remove and replace the battery in backwards and hook the cables up you will harm the electrical system . You're not removing the battery in this reset so don't worry about it but some shops will so kindly remind them of the uniqueness .

After a reset see if the other items fall in place

 

ok to be sure - we remove both Positive cable & Negative cable - then hold those 2 touching together ? for about how long? also we don't know how to remove radio so will it be ok to leave it be?

 

Yes as stated as long as you like the longer the better. I am unsure why it was suggested to remove the radio as once the battery cables have been removed it is not receiving any power. I don’t believe the radio should have a code required for your car?

 

Yes on both cables , here is the logic : in a minute

Stereo will slide out without removeing the wood " ski slope " trim piece

This negates the possibility of the stereo anti - theft " radio code " from locking out it's turn on function . I could be wrong . Radio codes can be retrieved by the Jaguar shop if lost in the removal process as a backup .

Remove stereo by first key on and bringing back the shift knob for removal clearance and then key off and then positive battery cable only removed . Remove all radio connectors . reconnect battery and place shift knob to park .

Proceed with " hard reset "

 

US Spec cars don't normally have radio codes

 

That explains why I haven't messed up yet (on that )

 

I found a skinny white wire with plug - just laying over other wires behind battery area
not sure why or what for ?

 

I have a photo but don't know how to send it here
we are about to try a Hard reset and saw it first

 

so I did the Hard Reset and I got back use of the bonnet interior release button and outside bonnet button but I neglected to close the drivers door all the way so after reset - it appears my door doesn't close all the way as it did before reset- am I imagining this or is this possible ? I am about to do another hard reset but need to be able to close door properly maybe while cables are touching each other - I can open driver door & close tightly ? these cars amaze me .

 

The security system is designed with one thing in mind and that is keeping the car theft proof . That includes someone tinkering with it as trying to trick it or bypass it . One of the last things considered as it is designed is how to work on it and resolve an issue . Some things are purposely designed to allow ease of maintenance otherwise the equipment is out of service and not earning you any money like a airliner or in a cars instance , the use of the car . This can be understandably frustration in this examples instance .

By drivers door not able to close all the way before reset does the exterior sheet metal go flush that it is mechanically closed thereby the locking mechanism is properly engaged ? You my have to use the hand key to open the mechanism and allow the door in question to go to close or zero state as you resequence the security system to zero state ( or all buttoned up ) during a hard reset .

 

Today we got the brand new drivers door latch assembly & actuator in so its back at the garage and he will disconnect battery while replacing it - and will adjust the door- I hope this finally resolves the drivers door prob- then if the rear door continues to make cycle sound but not working with key - will ebay a used latch & actuator assembly I will buy to replace; will know more later today -thank you all so much - I am learning a lot from you all .
