Wow no engine size stated, and MATTERs.!
with no tech1 or 1a scan tooL (real scan tools)
what good is DLC?>
sure jumper CODES< (DTC errors in todays parlance)
there is abs tool.. but only on some cars.
and more. read the FSM yet?
lets pretend you said how do i get the PCM flash error codes
easy jumper the DLC. 'diag, link connector"
google Isuzu DLC jumpers, nets you all this.

there is no world standards for OBD1 so DCL are
every freakn where.
in cab or engine bay or like hondas, on PCM casiing
wild and wolly DLC>

Multi-Port Fuel Injection
Amigo,Trooper II , Rodeo & Pickup
On Rodeo, Amigo, and Pickup (except 1993-95 models W/3.2L engine), connect the single wire diagnostic leads located behind the left hand kick panel together. On 1993-95 Rodeo models W/3.2 engine, the data link is located under the left hand side of the instrument panel. On all models, turn the ignition switch to the On position. At this point, the "Check Engine" light should flash. codes

SOURCE: Where is the obd port
Here is a photo of the obd connector on a 1993 Isuzu Trooper.
The connector is on the transmission hump about 6 inches from the accelerator pedal. It is inside a black hood. Right next to the white OBD connector is an identical green connector that I have not tested.
The OBD port is a white 3 hole plug. Right next to it in the photo is a green 3 hole plug that I believe is for automatic transmission diagnostics. The plug is different from other plugs under the dash as it will not accept a .25" tab connector.
The picture shows a 20 ohm resistor being used to short pin 1 and 3 of the white plug. The resistor is to prevent a melted wire in case the plug shorted is the wrong plug.
To read the error codes from the engine computer, the mechanic is supposed to short pin 1 and pin 3 of the OBD port plug. Then the mechanic turns on the ignition switch and counts flashes of the "check engine" light to determine the error values being reported.
