    The orange light in the dashboard is called Malfunction Indication Lamp (MIL) or Check Engine Light (CEL). Vehicle can only be repaired successfully if we know about the location of the problematic area, It can be diagnosed either with the help of diagnostic computer or by retrieving the codes manually.

    In Toyota diesel vehicles produced in 2004 the codes can manually be retrieved through the Data Link Connector (DLC) which is 16 pin connector located below the steering wheel. It is some what D-Shaped female connector. Its upper side is little wider than the lower one. On the wider side left most pin is number 1, next is number 2 and the last pin on the same side is number 8. Pin number 9 is just below the number 1 pin and pin number 16 is the lower right most which has 12 V DC all the time. Now to retrieve the codes connect the pin number 4 with pin 13 with a paper clip or 2 inches of auto wire bared at both the ends. Sit on driving seat, switch the ignition to ON, (but do not start) and look carefully at MIL. As you switch the ign ON, the check light will remain off for about 3 seconds and then will start blinking. The first blink will stay on (count TENs) for a while, then the rapid blinks will start (ONEs). For example if the first long blink glows 1 time and short blinks glow for 2 times, interpret it as 10+2=12. The blink code is 12 ( Timing control valve). Now retrieve the code and write it here. You would get the answer.

    There can be more than one code. Starting from the smaller code first, then long pause and then ending up with the larger ones. Jot them all on a paper and re-check two or three times to confirm.

Orange light mostly denotes the Malfunction Indication Lamp (MIL) or Check Engine Light (CEL) to tell the driver that there is fault in the engine electronic system. To locate the problem it need to be scanned with diagnostic computer or other wise it could also be checked by retrieving the codes manually.

A clogged EGR valve can cause loss of power on the x-type diesel. The best thing to do is to remove the valve and clean out all the carbon that will have built up inside the valve and re-fit. Also check your air filter

2008 toyota hiace lack of power

what even? we cant guess that?
lots of engines used, world wide, and country ?
lack of power can be cause by 50 things. on all engines.
but ill roLL the dice for you and land on GASOLINE, (not diesel)
1: never tuned up this decade, (spark plugs, filters. , fluids,etc)
2: bad spark.
3: loss of fueling to one one or more cylinders. or bad compression.
4: leaking injectors.
5: ECU/PCM , in limp home and owner not using a scan tool to scan it and see why. and ignoring the CEL lamp (check engine lamp)
there are lots more, but all checks take tools.
so are you DIY ? and have tools? or are you just wanting a guess.
i guess #1, the all time cause of car engines not running right.
lack of proper service.

Check engine light on and flashing, car shaking, all of a sudden

you have a bad engine missfire. a flashing check engine light means you are in danger of damaging your catylitic converter and you should scan the car. most causes of missfires are plug wires and or coil pack.
