Where is the obd2 connector location on holden ra rodeo v6


isuzimpuls.gif
Connect white (test lead) and black (ground lead) wires that are branched from harness approximately eight inches from ECM. After leads are grounded, the "Check Engine" light will flash the diagnostic trouble codes. The DTC's are indicated by the flashing CEL.
FLASH, FLASH, pause, FLASH, FLASH, FLASH = Code 23.
If only one diagnostic trouble code is stored, the DTC will repeat continuously until test leads are disconnected. If more than one diagnostic trouble code is stored, each DTC will repeat three times, starting with the lowest, then proceed to the next DTC. After all DTC's have been displayed, the pattern will repeat.I-MARK 84-85
Connect male and female test leads taped into wire harness near ECM. After leads are connected, the "Check Engine" lamp will flash the trouble codes. The DTC's are indicated by the flashing CEL.
FLASH, FLASH, pause, FLASH, FLASH, FLASH = Code 23.
If only one diagnostic trouble code is stored, the DTC will repeat continuously until test leads are disconnected. If more than one diagnostic trouble code is stored, each DTC will repeat three times, starting with the lowest, then proceed to the next DTC. After all DTC's have been displayed, the pattern will repeat.
86-87 Impulse located near the ECM connector, is used to actuate the Engine Control Module (ECM) trouble code memory within the module. Two terminals (A and C) of this connector are used to activate the diagnostic trouble code system in the ECM. With the ignition switch turned On, engine Off, connect a jumper wire between terminals A and C. The "Check Engine" lamp will begin by flashing a DTC 12. DTC 12 = flash, pause, flash, flash. There will be a longer pause and a code 12 will repeat two more times. This code indicates the self-diagnostic system is operating. The cycle will then repeat until the engine is started or the ignition is switched Off. In most cases, DTC's will be checked with the engine running since no DTC's other than DTC 12 or 51 will be present without the engine running. Remove jumper wire from ALDL connector before starting engine. Reconnect jumper wire after engine is running.

Throttle Body Fuel Injection

The ECM test connection is located under the center console.
A built-in, self diagnostic system will identify problems in the throttle body fuel injection system. When a problem is detected, the diagnostic system will illuminate the "Check Engine" light.
When the engine is started, the Check Engine light should turn off.. If the light remains lit, the self diagnostic has detected a problem. To determine where the problem exists, ground the "Test" terminal of the connector with the ignition On, engine Off and watch the check engine light. Each DTC will flash three times (lowest to highest).

Why is there a beeping noise every 5 minutes or so while driving-


AS LONG AS YOUR CAR IS RUNNING FINE & HAS BEEN SERVICED RECENTLY YOU CAN ALTER THIS MESSAGE ON SCREEN TO STOP THE BEEPING, THE EASIEST WAY IS TO DISCONNECT BOTH THE + & - BATTERY LEADS & CONNECT THEM TOGETHER FOR AT LEAST 30 MINS, THIS WILL RESET THE JEEP'S MEMORY, CONNECT BACK THE LEADS & THEN WHEN YOU GET IN & START YOUR CAR THE DISPLAY BY THE GEARSHIFT WILL BE FLASHING - SET THE CLOCK BY KEEPING YOUR FINGER ON THE SET BUTTON FOR S FEW SECONDS UNTIL THE IST DIGIT BEGINS TO FLASH, THEN PRESS THE SET BUTTON UNTIL YOU REACH THE DESIRED HOUR, THEN PRESS THE SELECT BUTTON BELOW & THIS WILL MOVE YOU ON TO THE MINUTES, CONTINUE WITH THE ABOVE OPERATION UNTIL THE TIME & DATE HAVE BEEN SET, YOUR "SERVICE" SHOULD NOW BE RESET TO EITHER 7500 MILES OR 12500 MILES, I SERVICE MY 96 GRAND CHEROKEE MYSELF SO THIS IS MY "CHEAT" FOR THE SYSTEM & IT IS GUARANTEED TO WORK. BEST OF LUCK.

Beep Error During POST



the beeps are post during post the very first work is done by the ram,all the memory in the ram is first transferred to the hard disk,and remains active untill turned off.

make sure that your RAM and Cmos battery are securely seated


Test all leads that attach to your hard drive including electrical extensions IDE SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them they could be faulty

graphics card is seated properly with no dust in the socket you might have to remove it to check for dust

a computer needs power and data to travel through every working device and to its continue its cycle and to have and end to function

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure make sure the connections and are not faulty even the electrical extensions or just replace them they could be faulty
a computer needs all electric current and computer data to travel to and through every working device and have an end to work properly click start right click on my computer so any faulty leads will end up with a computer error

hope this helps you

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((MOTHERBOARD TO YOUR HARD DRIVE))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error even something as small as a faulty electrical extension or fan lead can cause this problem

follow the troubleshooting procedure a computer needs all of the data and electrical current to travel through every device and to have an end to be able work properly

a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail check all electrical extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working also it could be a dirty computer clean all of the dust from your computer you could use a vacuum cleaner but whatever you use make absolutely sure there is no moisture gets to anything in your computer and before you touch anything be sure to wear an earth strap hope this helps

Power on but no display processor fan running power switch light off


Power light possible means nothing, maybe a burned out led.
No display: Try feeling the cpu heatsink to see if its getting warm. If it is cold after 15 minutes running, the CPU may have failed. If warm, move onto the graphics. If using onboard, try using an aGP card and see if you get a display then.

(I'm assuming that you get a beep on powering up? If you get no beeps at all, confirms CPU is at fault, if 8 beeps on start up, probably graphics. any other beep codes, post them and I (or somebody else will help)

Alternating green and orange light with constant beeps


Verify that the usb to ups cable is pluggled in properly. Also you may not have a good ground. Disconnect the ups and plug it in another outlet to test with nothing else plugged into it, to see if it still beeps. You can also try and upgrade the ups software from apc.com

1994 CHEVY CAVALIER V-6 STARTS TO OVERHEAT WHEN A/C RUNNING. ALREADY CHANGED THERMOSTAT AND ADDED COOLANT, STILL RUNS HOT, SOUNDS LIKE THE COOLING FANS AREN'T COMING ON WHEN THEY ARE SUPPOSE TO. CONSTANT...


Make sure you get the air out. There may be "high spots" on the engine that you can unscrew to let the air pockets t. Close this small valve when just hot water comes out.
Unplug the radiator fan and use jumper leads to test the fan operation. Use a scan tool to check for codes. If you get a scan tool that gives live data, see that the PCM sees the actual temperature of the engine after 5 to 10 minutes of running. It should see the temp. rising to 225 degrees farenheit.
Replace engine temperature sensor if the PCM doesn't recognize the proper temperature. You ARE going to compare this to the temperature gauge!!!
If all else fails, get the PCM recalibrated or flashed at the dealership.
