This is OBD 2 and u will need a scan tool to access trouble codes, this system started in 96, on old pre 96 system u could blink the check engine light and get the code. U CAN GO TO ANY KRAGEN OR AUTOZONE AND THEY WILL TEST THE SYSTEM FOR TROUBLE CODES FOR FREE.

Midgate closed window up dash says midgate ajar. Its fully closed


Hello Anonymous,

These system are controlled by an electronic module that should
send a fault code to the BCM (Body Control Module) and accessed via the DLC (Diagnostic/Data Link Connector) if a fault is present.

Some Auto parts stores will connect a OBDII scanner to your vehicle for free and provide you with a starting point should any fault codes be present. Fault code scanning is always the first step in trouble shooting a problem.

How do I retrieve the codes from the diagnostic connector of a 1994 Olds Ciera? I need a picture of the connector to see if it is the same as my car. Thanks


LOOK UNDER DASH ON DRIVER SIDE FOR 12 PIN DLC USE JUMPER WIRE OR PAPER CLIP TO TERMINAL A AND B THAT WILL BE LAST TWO UPPER TERMINALS TO THE FAR RIGHT. FLASHING CHECK ENGINE WILL GIVE YOU MORSE CODE LIKE 2 FLASHES FEW SECOND PAUSE THEN 3 MORE FLASHES IS CODE 23 YOU WILL NEED CODE BOOK TO LOOK UP TROUBLE CODES.

This is not a fuse problem. You will need to have your vehicle scanned in order to retrieve the trouble code as to why the light came on and then diagnose/ repair the issue. Hope this helped

Where is the computer test port on a 1995 isuzu rodeo


This is straight from Haynes Repair Manual for 1989-1997 Isuzu Amigo/Rodeo/Honda Passport (book # 47017:
The 12 pin Assembly Line Data Link (ALDAL) terminal is located under the dash on the driver's side on 3.1L engines. To retrieve the trouble codes, connect a jumper wire to terminals A and B. It may be covered with a plastic cover. They suggest using a paper clip to jumper the two terminals-then turn ignition switch to ON position (NOT ENGINE START). Check engine light on dash will flash-one flash-a pause-then two short flashes-indicating code 12-diagnostic mode. After self checking-if there are any trouble codes-the light will flash proper codes using mentioned method.Note the flash code then call a shop with your info for what ails your Rodeo.

Troube code retreaval


You shouldn't need to jumper anything; there is a standardized connector for code readers and it is generally on the driver's side under the dash. Please don't try jumping anything in that connector, you may damage the ECU if you connect the wrong two pins.

Call any of the chain auto parts stores and ask if they will retrieve the codes for you. This is widely available and is done at no charge.
