CEL and blinking cruise control light issue

[tintinz]

Hey guys and gals

other day my CEL light came one solid and the cruise control light started blinking and I have read from overseas forums that when CEL light comes on any newer shape subies this disables cruise control (not that I have used it) and a lot of people also say that it is caused by a loose fuel cap as the car does a vacum type check and if you dont put your fuel cap back on properly these lights happen.

I am resisting taking this to Wingers as they are a bunch of twats who rip you off bigtime and have mis-diagnosed my car on two previous occasions and charged me the earth for my pleasure. Do you guys know where I can take my car on a weekend to get the codes read or someone with a OBD code reader? short of doing the old disconnect the battery trick to reset the codes I would prefer the codes read first just in case its something serious

cheers

i thought all subies had diag plugs? if your legacy has the plugs you can have a go yourself, have a look at what the codes mean and ask for advice on here on how to fix the prob.

[tintinz]

they do have diag plugs near the steering wheel column but I need an Onboard Diagnostic code reader which I dont have one

[dubbedup]

will it not flash the codes? do you have a aftermarket ecu?

[tintinz]

not sure what you mean flash the codes and no I do not have an aftermarket ECU ... its a 2004 Legacy GTB wagon and I cannot see any codes flashing. All I get is steady check engine light on (sometimes goes away) but the cruise control light is always blinking

[dubbedup]

have you plugged the diag plugs together?

[tintinz]

no sorry how do I do this thanks

That doesn't work on the BL/BP.

Get in the car, shut the door and key off.

The rest has to be done within about 15 secs.

Turn the key to on.

Turn the parklights on (with the headlight switch).

Press the tripmeter button 4 times.

Turn the park lamps off.

Press the tripmeter button 4 times again.

Turn the park lamps back on.

Press the tripmeter button another 4 times.

It should now display the fault code number in the odometer display. Each press of the tripmeter button displays the next fault code.

I'm guessing you're going to have P0031, H02S heater control circuit low (bank 1 sensor 1). Basically means the heater circuit in the front oxygen sensor has burned out.

If you press the trip button 3 times (instead of 4) in the above process, it runs the cluster test sequence. Both are ended by turning the key off. Remember to switch the park lights off too.
