not to worry found codes for those who dont know them here they are,
Fault codes
1111 No codes stored
11 Crankshaft position sensor (Don't confuse with above, usually when the crankshaft sensor if dodgy the thing won't start anyway)
12 Starter switch faulty
13 Camshaft position sensor
14 Injector no.1
15 Injector no.2
16 Injector no.3
17 Injector (You guessed it!) No.4
21 Engine temp sensor
22 Knock sensor
23 Mass air flow sensor
24 Idle air control sensor (usually accompanied by running too fast/slow)
31 Throttle position sensor
32 O2 sensor
33 Vehicle speed sensor
35 Emissions canister purge valve
38 Torque control signal (Automatics)
42 Closed throttle position
44 Turbo wastegate regulator malfunction
45 MAP sensor
49 CO adjustment resistor for older cars not fitted with cats
51 Neutral switch (Manual gearbox)
Remember just because the fault code states a component it does not automatically mean that part is knackered. ALWAYS check the wiring, connectors and battery terminals etc. before galloping down to the dealer with your wallet flapping!
Dynamic mode
Get the engine to operating temperature, when the cooling fans have just switched off.
Turn the car and ignition off.
Connect the green conectors this time (No.2 in the picture)
Switch the ignition on but don't fire it up or it won't work!
Check the management light is on. If it is you can start it up.
If the light doesn't flash drive the car above 10mph for about a minute, no less than 30 seconds.
Stop driving and rev the car up to 2000rpm for at least a minute (this is great when you have an Impreza Turbo with a big exhaust!)
Count the flashes on the management light. Remember a long flash is 10 and a quick flash is 1.
Compare the code to the list above.
Turn the ignition off and disconnect the green connectors.
Thats you!
How to clear them!
Make sure the engine is up to normal temperature (the cooling fans have just turned off)
Turn the ignition off
Connect the green connectors together
and connect the black ones together too
Switch the ignition on but don't start it.
Check the management light is on.
Drive the car for about a minute above 10mph
Stop and rev the car to at least 2000 revs for at least a minute
Check the light flashes 4 long flashes (Indicating fault code 1111)
Switch the ignition off and disconnect the green and black plugs
Thats you! Easy wasn't it?
