Joker posted a topic in Gearbox and Drivetrainyeah its been done a brazillion times in all makes & models (sure it seems easy ground the neutral wire & bung the hardware in) but its never quite that easy is it? across the gens & models? or please point me to nearest thread because I cannot seem to find one anywhere or help us make one with pretty pictures & details & stuff, even if it is for one particular model etc I want to add it tot he FAQ section
faq ClubSub Technical MEGA FAQ *Beta*
kamineko posted a topic in General FAQ (Read Only)In lieu of a new Technical board structure being implemented soon, here are the workings for the new FAQ posts to replace all technical stickies, and hopefully most of your searches. This is a temporary post because it isn't helping anyone locked away while I'm too busy to finish it. Please post additional useful links as a new post for a Mod to add to the list. Mods, I've tried to categorise things logically and keep double-ups to a minimum. PM me any questions.

DIY AFM help
Durty-Sanchez posted a topic in Engine RelatedRight.. the AFM fixup guide! This is probably most relevant to early-mid 90's AFM's that have no servicible parts in them. The basic idea is that over time the solder joints on the connectors become dry and crack, which makes for a bad electrical connection and sometimes an error code. Even if no code is given, you may experience random loss of power from time to time, which can also be caused by this. Sorry about the blurry photos, it was a crap camera! Anyway, moving on, you'll need: Solder Solder wick/sucker (optional) Soldering Iron (preferably a hot one) Knife Silicon or some other kind of sealant. 1. Locate your AFM on the drivers side of the engine bay. It's attached to the airbox by bolts, and to the flexi-joint pipe by hose clamps. It's probably wise to unbolt the AFM completely from everything, although not necessary. You'll need to unplug it too! 2. After getting the AFM off you'll need to cut through the black sealant that lines the outside of the circuitry housing. The lid is quite deep so be careful when prying it out, I managed to crack the outer casing from prying too hard. 3. After you get the lid off you'll see a copper EM sheilding plate that is soldered down by one side. If the plate is loose then awesome, take it out, otherwise you'll need to remove the solder to get the sheilding plate out. Solderwick is great for this kinda stuff, but i'm sure there's more than one way to skin a cat. 4. Once that's out of the way you can see some of the circuitry involved in the mysterious AFM. Down one side you will see 4-5 connector pins that go from the main plug on the outer casing through to the circuit board (see number 3 on this incredibly blurry excuse for a photo). Usually these are the culprits! It's always best to remove the old solder before re-soldering, but you can probably get away with not doing that. If you look down at the pins inside the casing you'll see that they are actually made up of 2 pins connected with a solder joint (one from the circuit board, the other from the plug). Heat the joint so the solder is liquid then remove the old solder, then add some more solder as necessary. If you don't have solder removing stuff then i'm sure that re-wetting the joint should be ok. Repeat for all of the pins. 5. You're done! Put the EM sheilding back on and re-solder it to the grounding connection. Then replace the plastic lid and seal it with sealant to keep moisture out. This should conclude your adventures in to the AFM, and should be enough to have repaired it. I've done several of these and never had any more problems with them afterwards. If you're problem persists then you may need to either buy a new AFM or find one on trademe. Best of luck!
faq Check Engine Light Codes - MY1989 to MY2000
RAYDEO posted a topic in General FAQ (Read Only)How to Read Trouble Codes From the ECU On the gauge cluster, to the top left there are a few idiot lights which are not on under normal driving conditions. One of these lights reads 'check engine.' This light comes on when the ECU detects a fault in one of the many electronic components from which it receives signals and to which it transmits signals. If the ECU recognizes a problem while the car is on, the 'check engine' light will be constantly illuminated. If it has detected a problem in the past, but the problem which it detected no longer exists, the light will be out. However, the ECU will store a record of the faults it has detected in the past until they are cleared deliberately or unintentionally. To read any current or past faults, the 'check engine' light will flash in a sort of Morse code, which we can decipher. Underneath the steering column is a wide rectangular piece of plastic, the same color as the dash, which has a tray marked 'TRAY.' This large piece is held to the underside of the dash with a bunch of screws. Remove these screws and remove the plastic piece. Now there will be a bunch of wires for you to see. To the left of the steering column (at least in left hand drive cars) somewhere probably tucked away will be a bundle of wires with two pairs of electrical connectors which are disconnected. One is black and connects one wire to one wire, the other is green and roughly 'T' shaped, this one also connects one wire to one wire. With the car turned completely off, connect the black connector. Next, turn the ignition to 'ON' but do not start the car. The idiot lights in the dash will come on, and some may go out after a few moments. Watch the 'check engine' light and maybe have something you can write on to remember the codes. If there is a fault code in the ECU, the 'check engine' light will begin to flash in a particular manner. The codes range in number from 11 to 52, so we know that they all will be two digits. To signify the tens place of the number, the 'check engine' light will flash a long (1.2 seconds) flash. The single digit will be a short (.2 seconds) flash. Each flash within the same code will be separated by .3 seconds. Each error code will be separated by 1.8 seconds. Don't bother trying to time all these, just watch the light and you will begin to understand. Once the ECU has flashed all stored codes, it will loop through and repeat them. Now, for example, you see two long flashes followed by two short flashes. This means you have a code number 22. By looking at the following chart, we see that 22 is the code for the knock sensor. Once you have read and recorded all faults, turn the ignition off and disconnect the black connector. If you have done the above procedure, you will likely wonder what the green T-shaped connectors are for. These are for a more active code reading procedure called D-check mode in the Subaru manuals. Start with both connectors disconnected, start the engine, allow it to warm up, then turn it off. Next, connect the test mode connectors (green T-shape). Turn ignition to ON position without turning on engine. At this point if the check engine light does not come on, it is faulty and must be fixed before continuing. Depress accelerator pedal to floor, return to half throttle and hold for two seconds, then release. Start the engine. Now the light can blink in two different ways. If everything checks out so far, it will blink to indicate a number 01, 02, 03, 04, 05, 06, 07, or 08. If a problem is already detected, it will blink according to the chart below. Either way, your next step will be to drive the car with the test mode connectors connected. You must drive over 7 mph for at least one minute, and shift up to 4th gear if you have a manual tranny. Now, either you will discover your trouble codes, or you will have none. To erase trouble codes from the computer (without resorting to the infamous battery disconnect dance), repeat the above procedure exactly, but connect both the green and black connectors at the appropriate time.
