This tutorial will tell you simply how to check any fault codes logged in
yourcar, in a cheap cost effective way without the hassle of paying a garage £50 for a diagnostic check
Tools
No specialist tools are needed, only 2 working feet are required, 30 seconds of your time and pen & paper to write down the codes
STEP 1:
Get inside
yourvehicle a firmly place yourself in your seat. Once in, press both the accelerate and brake pedal together
STEP 2:
With both pedals pressed, put your key in the ignition and turn it to position 2, which is the position that switches all auxilary heating on but not the engine
STEP 3:
Once done, the spanner light will start flashing
if it flashes 10 times it means the number is '0' and any other flashes corresponds to a number with a pause between each number
for example code P0110
the light will flash ten times then pause (2sec Or 1 not sure) flash once, (2sec pause) flash once, (2 sec pause) then flash ten times
if you have more than one code it will stop for a break between each code
however if you don’t have any code stored it will start Flashing and keeps on flashing until you release the pedals
If you follow the above steps you are certain to find codes without ever having to plug an OBD equipment
