CX-5 / Stopped running on 3 cylinders
« Last Post by David on July 09, 2024, 01:29:33 pm »
Hi some time since last post, spent 12 months getting new injectors dismantle intake etc and carbon clean (and buying camera to check valves closed)
Since which has run fine for 6 months. However last week in for Service all I fine until finished standing ticking over suddenly stopped firing on cylinders 2,3, and 4 run's on1 for a while then dies. Will start on number 1 and run but will be obviously needed to be stopped.
Initial reaction it was use diagnostic which showed loads of Cannot Communicate errors So ECU failure we thought.
But when started again diagnostic machine shows no errors????? But still only number 1 runs
Many reasons why just one cylinder may fail but 3 at once, any ideas
Mechanic is going to pressure test cylinders before moving back to getting ECU off and sent for testing
Update No compression on the 3 dead cylinders
Vehicle Electrics / Airbag warning light code 2-1 and battery voltage
« Last Post by Portside on July 08, 2024, 10:59:28 am »
Hi everyone,

About two weeks ago the airbag warning light started flashing, two flashes follwed by a single flash.  I took it to an indepdent Mazda garage.  Their scan tool showed a high resistance in a component related to the front passenger seat occupancy-classification-system, but it was not clear which component.  A visual check was made under the seat for any loose connections or obvious damage, but nothing was found.  Garage said they would research the problem and get back to me, and I took the car home.  However the garage can't seem to find an easy answer and suggested bringing the car back for more inspection.

I did a bit of research myself and found a technical bulletin about the seat pad sensor triggering the airbag warning light on start up, under high current draw conditions such as starting in cold weather, due to the 'low voltage detection time being too short' - could this appear as a high resistance?  However, the airbag warning light issue didn't occur in cold weather.  Neverthless, this information prompted me to check the battery voltage.  After leaving the car overnight it measured 12.2v.

For context, the car works fine in all other respects, and starts with no issues.  It is 6 years old, and I believe the battery is original.  Due to our usage of the car, it makes loads and loads of short trips every week (averaging 6 miles per trip).  Also, in the last few months I found my partner adjusts the seats (electrically adjustable seats), while sitting in them, with the engine off, which can't be helping the battery.  My measurement of battery voltage was done with a multimeter, not a car specific tool, measured at the battery terminals with all accessories off, but immediately prior to making the measurement I had to unlock the car to open the bonnet.

Apologies if this is a slightly muddled post, but the questions I ask myself are:
- could the low battery voltage be causing the airbag light?
- even if the airbag light is not related the battery, should I change the battery anyway?
- what component needs replacing in the airbag system (front passsnger seat occupancy detector).

The car is a 2nd generation CX-5, petrol, SportNav+, ~60k miles on it. It is no longer covered by any warranties.

Grateful for any suggestions.

Modification Projects / Fitting running boards
« Last Post by jonybravo78 on June 12, 2024, 04:39:28 pm »
I've bought running boards and fittings online, and taken the CX-5 to a garage to have them fitted. The fittings have brackets to support the back, the middle and the front of the running board. So 3 areas across the length of the car.

The garage have said that my vehicle does not have drill holes for the middle brackets, and it wouldn't be safe to fit the running boards only to the back and front of the vehicle.

Mine is a 2013 2.0L Petrol

Anyone had any experience of fitting running boards to the Mk1 CX-5?
Steering/Suspension/Brakes / Electronic handbrake issue
« Last Post by Tiger on May 07, 2024, 07:37:24 am »
Hi all; any advice appreciated

My 2019 cx5 has the amber warning light on the dash for the electronic handbrake.

When the engine is on I can’t put the handbrake on. When I try the light in the handbrake comes on and then goes off again immediately when I let go of the switch.

When I then turn the engine off the handbrake will come on (so suggests to me that there is no actual issue with the handbrake itself? Maybe a software issue?)

Any ideas on how to reset or fix this without having to take it into a garage?

Plenty of on line car dismantlers; just google for them. Try E bay too.
Exterior Trim / Damaged wing mirror trim
« Last Post by chubnut on April 29, 2024, 03:11:31 pm »
I damaged the lower nearside wing mirror trim that sits on the lowerpart of the bracket that holds it to the door. Does anyone know where i could get a new one. Mazda say in will have to buy new mirror, at £90 thats not an option. Have been trying to find scrap yards but these seem to be disappearing rather fast. Any help appreciated

The CX-5 achieved a solid five stars in the Euro NCAP crash tests (2012). Features include stability control, traction control, automatic city braking and curtain airbags.

I have a problem with the nav system, I tried to do an update of the SD card; unfortunately due to a faulty sd card reader it trashed the card.
I bought a new card from eBay with exactly the same numbers on it ( EUROPE 2014  KD51 66 EZ1B ) Now when I tried to use the nav system the startup screen displays correctly and then it displays "Problem with map You cannot use this map on this device: Europe_zone_1-101624"

Any ideas on how to fix this or do I return the new card and buy a different one?


Accessories / When did Mazda fit SCBS?
« Last Post by SteveAWD on April 26, 2024, 10:54:27 am »
Hi. I'm going to fit a tow bar to my 2013 2.2 sport nav CX5.
I've also purchased a Masda dedicated wiring kit C851-V3-921A.
I've read that to make this work for the caravan electrics, if the car has SCBS I will need a "split charge" relay fitted as well but I don't know when SCBS became current on the CX5.
Does anyone know the answer to this question. Many thanks.
