Is it possible to check diode and zener diode in laboratory?
yes, of course it is. one way is using a curve tracer.
What is a diode check setting used for on a dvom?
The Diode Check setting on a DVOM is a special ohms setting that presents enough voltage to the tested device to conduct, if it were a diode. Old style VOM's did not have this problem, because they usually used a battery greater than 0.7 volts to run the ohm's scale. Modern DVOM's, however, can use very small voltages to measure ohms, and that would not cause a diode to conduct. The Diode Check setting fixes this limitation.
How to identify the anode and cathode of DR 25 diode?
The cathode of a diode is usually indicated with a band. In the absence of the band, consult the datasheet. Alternatively, use an ohmmeter that generates more than 0.7 volts at low current (a diode checker) and check conductance. The diode will conduct when the anode is more positive than the cathode.
Difference between gunn diode and pin diode?
gunn diode is transfered electron device & PIN diode is semiconductor device
What is a real diode?
whether we know that p-n diode is real diode. But still in case of semeconductor we see then silics is real diode.
Where is pcm diode on 2001 Ford Explorer sport?
In the Power Distribution Box ( which is " live ) located in the engine compartment on the drivers side Location ( # 53 ) is the PCM diode on a 2001 Ford Explorer Sport
Gear display data error 2000 Lincoln?
CHECK THE PCM DIODE. Apparently these get loose over time.... I had the same symptoms, car would randomly not start. Drove me crazy for months. Then one day I was pulling the relays in and out and noticed the PCM Diode suddenly made a CLICK when I pushed it down. Apparently it was creeping out of it's socket over the years. All I had to do was push it back in, and voila! problem went away!! Btw, in my car, Lincoln Continental 1999, the diode is to the left of Relay 7 (PCM Relay). This solved the mysterious "GEAR DISPLAY ERROR", CHECK TRACTION CONTROL, etc., and PATS code 16.
Where is pcm diode on 2001 Ford Explorer sport trac?
On a 2001 Ford Explorer Sport Trac : The PCM diode is located in the Power Distribution Box in the engine compartment on the drivers side ( it is in location # 53 ) The PD Box is " live " Also , in the fuse panel located in the drivers end of the dash ( the fuse panel cover is visible with the drivers door open ) fuse ( # 19 is a 25 amp fuse for the PCM power diode )
What is a pcm diode on a 2001 ford explorer sport trac?
Powertrain Control Module diode ( from what I read , a diode is a one direction device which permits current to flow easily in one direction , but offers an extremely high resistance to a current trying to flow in the opposite direction )
What causes the 30 amp fuse 7 to blow while I am driving down the road on a 1998 crown Victoria Fuse 7 is in line with the PCM diode PCM Coil and parallel to the new ingnition coils I replaced?
It should be a 25amp fuse. start checking coils, or PCM.
What is the accs for a 1995 Ford Explorer?
In the power distribution box, in the engine compartment of a 1997 Explorer, (PD BOX IS LIVE - DISCONNECT YOUR BATTERY CABLES ) in location # 2 there is a 30 amp maxi-fuse for the PCM power relay in location # 11 there is a 20 amp maxi-fuse for the PCM MEMORY and horn Relay# 5 is the PCM POWER RELAY and diode # 2 is the PCM DIODE ----------------------------------------------------------------------------------------------------------- In your fuse panel - visible with the driver's door open location # 13 - 15 amp fuse - for PCM system/stoplamps/AWD/ABS/speed control/ trailer tow location # 19 - 25 amp fuse - for PCM system/ ignition coil

How do you check electronic diode?
you use an ohm meter
What does companion dtc mean on a pcm or ecm?
If the Pcm sets a code saying that it's companion has dtc, you need to check the Ecm because it will have a code in it.If the Pcm sets a code saying that it's companion has dtc, you need to check the Ecm because it will have a code in it.

What is the purpose is of a diode?
The purpose of a diode is to allow electric current to pass in one direction while blocking electric current in the opposite direction. It is for this reason that diode is usually referred as the check valve.
I have a 2000 plymouth prowler v6 check engine code reads p0601.if i reset the computer it will come back on at restart.?
P0601 is PCM internal processor failure.The PCM needs replaced.P0601 is PCM internal processor failure.The PCM needs replaced.
