General Panda 1.1 active 2009 drivers door lock

[koalar]

The light works manually only, think the courtesy switch is in the door locks?

Doesn't help much

Same as post 9

Could be any micro switch not closing

Operational description
The front interior light G010 is powered from the body computer node M001 (pin 10 connector F). Internal switch A can be turned to three positions:

position 0: front interior light switching on/off is managed from the body computer node;

position 1: the front interior light is always off;

position 2: the front interior light is always on;

In the following circumstances, the body computer node automatically switches on the front courtesy light following signal from the door locks N050, N051, N055 and N056:

if pin 23 connector H receives the negative signal (reference earth C020 connector B) for front left door open;

if pin 21 connector H receives the negative signal (reference earth C020 connector B) for front right door open;

if pin 15 connector G receives the negative signal (reference earth C030 connector B) for rear left door open;

if pin 4 connector G receives the negative signal (reference earth C020 connector A) for rear right door open;

if pin 13 connector H receives the negative signal (reference earth C020 connector B) for doors unlocked (central locking);

if pin 14 connector G receives the negative signal (reference earth C030 ) signalling inertia switch activation I050 .



The connection between the body computer node and the front locks N050 and N051 passes through door couplings D030 connector A and D031 connector A. Both are housed in the passenger compartment area, in the lower part of the left or right front pillar (depending on the coupling involved), near the door partition coupling. The door coupling D030 is located behind the body computer node.

The body node computer automatically switches off the front courtesy light in the following circumstances:

if pin 12 connector H receives the signal (reference earth C020 connector B) for doors locked (central locking);

if pin 14 connector G no longer receives the negative signal (reference earth C030 ) signalling inertia switch reset I050 .

The body computer node manages the switching on/off of the boot courtesy light G040. From connector G, body computer node:

to pin 18 supplying the bulb inside the boot courtesy light G040 ;

to pin 5, receives the tailgate open negative signal (reference earth C030 ) , from the external handle 1033 ;

to pin 13, receives the tailgate not fully closed signal (reference earth C030 ) , from the external handle 1033 .



Earth C020 is secured to the passenger compartment floor and is positioned near the right front wheel arch (footwell area). Earth C030 is secured to the left rear wheel arch (inside the passenger compartment).

Opening any door (front or rear) or the tailgate door displays the associated warning light on the instrument panel E050 . The control for switching on the warning light is supplied via the CAN from the body computer node.

See E1050 CAN CONNECTION LINES

. The door status signals on the instrument panel are activated only via the ignition.

Today the door card came off, sprayed what I could see (not much), still wants to bounce but think time that I’m holding the key over is getting less. Found a piece of window winder cable in the bottom of the door!
Going to keep spraying outside for now.

Keep trying to edit/save this message however, there is a large plate covering the back of the door handle,is this what has to be drilled out? It’s in a very restricted space, and can hardly see what holds it

Which door are you spraying

 

[cnikonpete]

Which door are you spraying

Driver’s door, the lock is just about visible, but there is a blackplate

Which door are you spraying

The driver’s door is the problem one. The inside has a large plate of some description covering the back of the door handle

There a micro switch in every door

Just because the key goes in the driver's door does not mean that's where the problem is, it could be any

Without software to read read the position of the switch, or taking the body computer out and measuring the pins with a multimeter, you only have a 1 in 5 chance of hitting it correctly working on the drives door

It's normally the rear the causes this problem in my experience

Thanks again, any idea why they all lock properly from the inside? I shall spray the back locks more, don’t really want to buy another lock,so spraying is my preferred option.
It does lock eventually, can’t imagine anyone stealing it anyway

Thought you would like to know Koala,you were right, looks like the o/s/r door will get things better with more spraying, many thanks for your patience .

No idea

It's a real thing, often they work from the inside

As a pure guess the body computer wait longer before timing out

It is what it is

If you open and close them from the inside it's usually the handle with a slight lag is where the problem is

I have a multiplexer and Delphi software, if needed I could watch the live data from all 5 switches at the same time and it would be pretty obvious which one was the problem

But without diagnosing the problem or some clue, it's just pick one from five

Most of the time, a good spray and oil is all that's needed, occasionally it's something else like a frayed cable

Thankfully very very rare

Try pressing each door lock button and then remote locking the car. The one that works is the faulty one.

Thanks, mine is key only,and I think I have found the dodgy lock
