hi guys,

 

i had a diagnostic check on my cmax which returned an b1602 fault, A Defn of B1602

B1602     Ford     At some time since last clear a (PATS) key used has not been read satisfactorily.

 

However my passenger door wont open, the immobiliser light flashes about 20 times then goes off and yesterday the engine management light came on. A mechanic told me that its the immobiliser but i think that the other doors wouldnt open if it was that and god only knows why the engine light came on.

 

the car itself runs great but starting it makes a god awful clicking sound that i have been told will eventually will get worse and the car wont start at all. it sounds like the starter motor but i was wondering if anyone has any other thoughts on this.

Hi Dave, first of all, immobilisers and doors are completely seperate worlds.

 

To open the other door, check you dont have anti hijack activated, if you press unlock once, the driver door only may open, if the unlock button is pressed again (or twice in quick succession) then the other doors may open.

 

If the passenger door is the only one not to open then it could indicate a failed lock, you would need to remove the door panel to work on the door itself and to get at the lock.

 

The flashing imobiliser light is the cars way of saying "I dont recognise the key", it could be that it has just forgotten about that one key temporarily or it struggled to read it (interference of some form) and that explains the error codes.

 

The immobiliser light though will play no part at all in your passenger door not opening.

i disconnected the battery for 30 minutes reseting it and the door now opens. the immobiliser wont flash when car is running it just flashes when car is locked and the engine management light has gone :). the cars error code b1602 which is the signal from the key to the ignition. would this cause the clicking on startup or is this something different, when the car starts it sounds like a diesel?

 

i have re-seated all fuses and just ordered a diagnostic kit to try and sort these problems out. I bought this cmax on 14th April this year, it drives fantastic and other than the problem with this clicking which is embarrassing i love this car. I bougg the dealer 5 days after i ht the car from a dealer M&H Cars at Barnsley, when i enquired about the clicking he said its the bearings in the starter motor so it could do with a new one, the passenger door sticks he said so ok i paid 1400 for it with 78,000 on clock and it was me and my wifes ideal car as we have two small children so i gave him the benefit of the doubt. I let a mechanic look round it as it was in for a service who told me the extent of what was wrong. He said that it was the instrument cluster and i was looking at a £550 bill. so i rang the dealer who constantly said its the starter motor and the car is in "A1 condition" i asked for my money back he pretty much told me to F**k Off. So i have decided to fix this car as its what we want and i intend to do the work by myself, so any help with these issues are greatly appreciated. Sorry for my grammer was on a bit of a rant.

Good call on the diagnostics, its always worth having as they are fantastic to have, I cant even think how much money mine has saved me over the course of its ownership, and for that matter, how much its saved other people I have helped with it!

 

 

the cars error code b1602 which is the signal from the key to the ignition. would this cause the clicking on startup or is this something different, when the car starts it sounds like a diesel?

 

 

Not entirely sure where this clicking is coming from, if its interior passenger footwell, it would suggest the battery is likely to need replacing soon.

 


when i enquired about
the clicking he said its the bearings in the starter motor so it could
do with a new one, the passenger door sticks he said so ok i paid 1400
for it with 78,000 on clock and it was me and my wifes ideal car as we
have two small children so i gave him the benefit of the doubt.

 

Could be the starter bearings, might be handy if you can shoot a video showing the noise and upload it so that we can advise it? You seem to have got a good deal though, in fact, one might think too good a deal?
£1400 for a relatively low miler of its age. Similarly to you, I bought it before the mondeo I have now for that very reason, it is an excellent family car, the wife and kids loved it, the boot space was fantastic
and it really was an excellent motor, its a shame I bought one with a dodgy gearbox!

 


I let a mechanic look round it as it was in for a service who told me the extent of what was wrong. He said that it was the instrument cluster and i was looking at a £550 bill. so i rang the dealer who constantly said its the starter motor and the car is in "A1 condition" i asked for my money back he pretty much told me to F**k Off.

 

Instrument cluster for a new one is £550, but to be honest, they can be repaired for £80 or you could do it yourself if your handy with a soldering iron. You should write to your dealer and advise them of ALL issues on the car, you have a 6 month guarantee with the car (warranty if you will) that means that if there is a problem, they have an expectation on the sale of goods act to fix it. Report the issues with the instrument cluster and advise that an independent opinion advises that it is faulty.

 

Your two options at this point are to send the cluster off for repair (around £80) if its fixable, if its in good health, its returned for a nominal fee (around £30 I think?) so you know either way you get it sorted. Alternatively, you can take the vehicle for further independent examination, and get a report from them to advise what the issue is, if you have to pay for this and they all advise the same thing, then you can provide this to the dealer and get it repaired under SOG act and get a refund for the reports you had to buy. Either way, you have every right to ask for your money back if the vehicle is not fit for purpose, unfortunately I dont know whether a noise would be deemed sufficient reason which is probably why he gave you two fingers.

will keep you posted, i need to sort the door out as it still locks on its own accord, i know that they are fitted with an anti hijack system so tried pressing the key twice but still nothing. door opened after a school trip and being locked and unlocked again so i soaked it in wd40 and it happened again an hour later. the clicking noise i can live with for the time being (least until my diagnostic kit arrives). just forked out for a new tyre new discs and pads so plenty to plod on with. will post more info when my kit arrives. Thanks for the advice so far.
