Central Locking Kaput..

[jarance]

OK here is a picture of what going into your car. It a plug-in relay come with base. That way if the relay contact is worn out, you just change the relay without having to do any soldering..

I will not shocked you with the wires that I am going to cut... snip snip.. no for the faint hearted.

I got a faulty GM5 module that was pass to me for repair.

After "playing" with it, i.e. cleaning, soldering terminals etc, I tried on my car. Well the problem seem to be solved for a few days. However, after a few days testing, the door refuse to open.. (!@#$%^&*) bloody GM5 module failed again. So back to square ONE.

Anyway, I decided to modify the circuit since the owner have given permission to do anything to get it work again.

I have modified it by adding another miniature power relay. Well guess what... It works!!!

Now the modified unit is still under testing for a week. so far so good. (Under hot sun, raining or any condition). I will continue to test it for 2 more weeks before I decide.

The beauty is, the repair cost is less than RM60 for material.. (if it work)

View of the connector at the back. The one with multiple pin is for the door lock. The one with thicker pin is for the power window.

The TYCO relay gremlin. I've helped my mechanic to actually source alot of those relays previously. I might have a few lying around somewhere in my home or office. If anybody needs them, do PM me. Can't guarantee I will be able to find them but I'll try.

Ade, if you can get the tyco relay model no: V23084-C2001-A303.

Please do let me know the price and delivery date.

The V23084-C2001-A303 relays and other relays, like the ones for the front windows, V23078-C1002-A303, are available from the web site mentioned in post #10 back in Jan '09. Cost of the relays plus shipping to Malaysia are reasonable.

week 4.. so far it have NOT give any problem. The extra relay added to circuit board help in keeping the module working.

Just remove the modified module from my car and install back my original GM5 module. After installing the original module, my key could not open/close the door. A quick re-syn procedure was performed and everything was back to normal again.

I think I have crack the code..

OMG, our sifu really go deep into this. Really experienced with all the technical graph. Jarance, i searched on net found that for CI, 323 and 325 is not much different.

323ci
170bhp, 0-60mph 8.9s, 1430kg

325ci
189bhp, 0-60mph 8.0s, 1485kg

Why there are still people buying 323ci but paying same roadtax as 325. Features ? Oh yeah, i was mentioned the 325ci msport without the Multi Function on the steering. Can it replace with M/F and work ?
