HI,

Last week my car got broken into. They didnt get anything but they stuffed the ignition a little. I got the ignition fixed and I also got a clifford alarm immobiliser fitted.

Today is the first day I have gone to drive it, and as soon as I drove down the street, the check engine light started flashing on. This hasn't happened before and I am pretty sure it probably has something to do with the guy who installed the alarm/immobiliser.

Does anyone have any ideas what this might be?

Thanks.

have you got a flash code ? , does it continuesly flash like 1,2,3,4,5 or does it go , 1,2,3 followed by 123 quickly?

hello mate heres a guide to clearing and reading codes,

How to clear the fault codes on your Subaru including Legacys and Imprezas
Most cars simply store fault codes and thats it. Subarus on the other hand have 2 modes. You can read the stored fault codes or you can check them while the car is driven. This is useful if you have a fault code that only appears when you drive and doesn't hang about long enough to be stored.

Reading and clearing the codes themselves is pretty easy. This method should work on all Pre 1999 Subarus with proper ECUs (so if you have a 1978 Brat pick up you don't need to read any more!) After 1999 Subaru began using the EOBD system on their UK cars. I am not 100% sure if the imports after 1999 can still be read like this. No harm in trying I suppose!

How to read the stored codes. Do this before you try the dynamic method.

Turn the ignition off
Find the diagnostic connectors. They are usually under the dash on the drivers side near the centre console. There should be a pair of black connectors (1), a pair of green (2)and a big yellow one (3 We don't need to worry about that!). You are looking for the black pair.
Connect the black connectors together.
Turn the ignition on but don't start it.
Check the engine management light comes on. If it doesn't some snake in the grass has disconnected it! This happens because people are scared of having to take the car to the dealer to have it fixed!
Count the number of flashes. Long flashes count for 10 and short ones are single units. So the code 38 would be 3 long flashes then 8 quick ones.
If it just flashes long flashes continually there are no codes stored.
Anyway, count the flashes and check against the list below.
Turn the ignition back off then disconnect the black connectors. If you mess things up just disconnect the black connectors and start again.

52 Parking Brake Switch (Exc. Justy)
53 Fuel Pump or Circuit
54 Choke Control System
55 EGR Temperature Sensor or Circuit
56 EGR System
57 Canister Control System
58 Air Control System
61 Fuel Tank Pressure Control Solenoid (Impreza)
62 Fuel Temperature Sensor (Impreza)
63 Fuel Tank Pressure Sensor (Impreza)
64 Vacuum Line Control Valve or Circuit
65 Vacuum Pressure Sensor
66 Sequential turbo system
67 Exhaust valve solenoid (positive pressure)
68 Exhaust valve duty solenoid

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

hope this helps you mate

Thanks for all the info Nathan.

the light just constantly flashes at the same pace. do you think that they may have just connected the green and black ones when they put the dash on and that is why it is flashing?

Thanks again.

Yep, looks like they've blindly connected the black ones together thinking they could hot start it, or something.

The black ones are the "Read" connectors that check for ECU fault codes... And equal on/off pulses means that everything is okay with the car's various I/O sensors.

Just reach up behind the steering column and you should see the black connectors connected. Just unplug them and tape or cable-tie them back up in a safe manner (carry out the same to the greens, if they also happen to be connected...)
