Guest andybaz Posted March 28, 2011 Posted March 28, 2011 Hi all, new here, currently trying to help my neighbour get their car going, Zantia N reg, 1.9Turbo D8B engine.Sympton: Keypad RED light on, key in ignition GREEN & RED light on, key in the 4 digit code and BOTH lights stay on - NO START. Asking for help here, value of car :) does not warrant going to dealer to be told needs new ecu's etc, and it would have to be towed any way adding to cost. Our keypad is the C & S button version, i understand that the pad has a facility where if you have lost or the pad wont except your code, it has a inbuilt programme to bypass ?. People talk about simply unplugging the keypad joining a couple of wires to get the car started. Our number has failed to work,BOTH RED & GREEN lights stay on, she cranks over ok, but wont start. Asking for any help, greatly appreaited. If some one has a procedure .... may be you could email us, im a toyota dealership techy, im also a ATA approved techy. 1 good turn deserves another, in the wrexham/chester area : require a code read, drop me a pm, snap-on diagnostic tool owner. Look forwards to all views and comments, cheers andy Quote
Randombloke Posted March 30, 2011 Posted March 30, 2011 Sorry mate, you've got the spammy tw*ts again, I'd love to ban them all. Keypad, similar to 406. If it's in the centre console, I would try lifting it out and examining for frayed wires or damaged wires, if it's hinge down job under the dash it's definitely damaged wires. There is as repair kit or you can solder then use Hellerman sleeving to cover the joints. Have a look at the diesel pump or the ECU at the other end of the loom for the same problem. Unplug the keypad from the wiring and see if you can see any dry joints (soldering) where the socket is on the circuit board. My first work around would be to pair the keys to the car, if you still have the plips working. Pair both plips to the car, search for instructions on line, this allows you 60 seconds to start the car AFTER it has been opened with the plip key. Then you can forget the pad. The keypad is paired with the diesel pump AFAIK on the 406 (PSA parent company, same floor pan, electrics and engines, just no hydraulic suspension) so I don't think you can swap the pad out easily. I had to get a repair kit to fix my pad but was able to pair keys and use this as a work around. It would also be worth looking for a minor fluid spillage and maybe using some circuit board cleaner on the keypad. Be careful though. Quote
