All problems which dtc380 are related to the injector nozzles getting blocked. Add some carb. cleaner to the fuel or spray some in the intake. If you do notice a slight change as if the engine is almost starting then add some more carb, cleaner, in correct proportion in the fuel tank itself ensuring that just agllon or half a gallon remains. If you are going to try it yourself, my advice/recommendation is to have a spare battery, fully charged, as standby in case the car battery gets drained while cranking the engine. Alternatively if you take it to a service station equipped with aPC for trouble shooting purposes, it will indicate precisely which injector nozzle is blocked, thus speeding up the repair work.........sodeep

Check the 'bus bar' feeding the glow plugs themselves. If anything is touching it, there's the fault.

RECOMMENDATION:


Following published diagnostics for DTC P0380, P0621 or a no charge condition may lead to unnecessary generator or ECM replacement. You should first check the 175-amp battery fuse. If the 175-amp battery fuse OR circuit 506 is open, no voltage will be present on circuit 506 at the PCM. This will cause the P0380 to set. The ECM monitors the glow plug signal using circuit 506. The ECM expects to see battery voltage on circuit 506 when the glow plugs are commanded on. If no voltage is present on circuit 506, the ECM will stop sending the turn on voltage to the generator L terminal circuit 25, causing the no charge condition and the P0621 to set.

Circuit Description

Modules connected to the controller area network (CAN) serial data circuits monitor for serial data communication during normal vehicle operation. Operating information and commands are exchanged among the modules. The modules have prerecorded information about what messages are needed to be exchanged on the serial data circuits. The messages are supervised and also, some periodic messages are used by the receiver module as an availability indication of the transmitter module. Each message contains the identification number of the transmitter module. A module with a CAN serial data circuits malfunction or which loses power during the current ignition cycle will have a Loss of Communication DTC set by other modules that depend on information from that failed module. If any of the CAN circuits are shorted to battery voltage, ground, or between them no communication is possible on the CAN serial data bus, a DTC U2104 is set.

    Conditions for Clearing the MIL/DTC:

    The MIL/DTC clearing depends on DTC type. For information about DTC types, refer to Diagnostic Trouble Code (DTC) Types in Engine Controls - 6.6L (LB7).
    DTC Type B
    • The MIL clears after three ignition cycles when the malfunction is no longer present.
    • A current DTC clears when the malfunction is no longer present.
    • A history DTC clears when the module ignition cycle counter reaches the reset threshold, without a repeat of the malfunction.
    DTC Type C
    • A current DTC clears when the malfunction is no longer present.
    • A history DTC clears when the module ignition cycle counter reaches the reset threshold, without a repeat of the malfunction.


  • INDIRA KUMAR
    INDIRA KUMAR Oct 01, 2009



    Action Taken When the DTC Sets
    • The module uses a default value for the missing parameter.
    • The malfunction indicator lamp (MIL) will illuminate on the second consecutive ignition cycle that the diagnostic runs and fails, for the type B DTCs. For a detailed description about DTC types, refer to Diagnostic Trouble Code (DTC) Type Definitions in Engine Controls - 6.6L (LB7).

Circuit/System Description
The glow plug controller has the ability to perform internal checks, an open or a short to ground on each of the glow plug circuits. If the glow plug controller senses a problem in a glow plug circuit, the glow plug on the affected cylinder will be disabled and the glow plug controller will send an error message to the engine control module (ECM). If this condition exists, the DTC will set.
Conditions for Setting the DTC
The glow plug controller detects that the glow plug control circuit is open, shorted to ground, or has more than 1 ohm of resistance.

Circuit/System Verification
Verify that DTC P064C is not set.
If DTC P064C is set, refer to DTC P064C.
Ignition ON, engine OFF, observe the scan tool Glow Plug 1-Glow Plug 8 parameters. All 8 Glow Plug parameters should closely match each other.
Refer to Testing for Intermittent Conditions and Poor Connections if you cannot duplicate the conditions.
Engine running, observe the DTC information with a scan tool. DTCs P0671-P0678 should not set.
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

DTC C0035 Left Front Wheel Speed Sensor Circuit
DTC C0201 Antilock Brake System (ABS) Enable Relay Contact Circuit
The system relay, located within the electronic brake control module (EBCM), supplies battery voltage to all of the valve solenoids and to the ABS pump motor.

I bought a van 2003 Mercedes mb140 diesel. Is always gone and Also the mechanic gave me the ok. Then i wanted to sue but the light for the engineering start didn't turn on anymore so the engine didn't...


check the glow plug relay / and fuse. if thats ok then you will need a meter on the glow plug wire to see if there is any resistance on the glow plug its self. if the relay is at fault just change it. glow plug has no resistance then it needs changing. if the fuse has blown check the wire loom for the glow plug wires as they can get hot and earth to the engine.

Glow plugs flashing when engine is running


HI. This is an indication of a failing glow plug. It will be necessary to test each plug to isolate the issue, or run a diagnostic scan on the CPU. During the scan, you should be issued a code that will isolate the actual glow plug that is malfunctioning. If you insist on testing each plug, use my procedure below to assist. You can find the resistance specs in your operators manual.


A test light can be used to determine if the glow plugs are working.


1. With the test-light grounded, insert the test light probe into a glow-plug wire to check for continuity.

2. If the light comes on, check the other cylinders in the same manner. If the test light failed to light, check for continuity at the glow-plug relay.

3. If no power is present, check the control circuit of the glow plug relay.

4. If the control circuit is working, the relay may be defective (FYI, manufacturers may have the system fused and fusible links may be located throughout the system).

5. If the glow-plug circuit is working, the glow plugs themselves may be defective.

Checking glow-plug resistance:(Remove the plug for this test)

1. With an ohmmeter, connect one lead to the terminal and the other lead to the body.

2. Read the resistance and compare to specifications.

3. A visual inspection may also be necessary to check for excessive carbon buildup and physical damage to the tip.

4. A glow plug that has excessive carbon deposits on its tip can give the correct ohmmeter reading but still not work. Clean the tip with carbon cleaner.(DO NOT USE A BRUSH TIP CLEANER)

There doesn't seem to be power to the glow plugs when there should be


How did you determine there is no power getting to them? If the glow plug light comes on and then turns off immediately, that is the glow plug controller telling you the glows are burnt out.

Test the glow plugs by using a multimeter with an ohm tester. Take the engine cover off and pop the glow plug wires off the glow plugs. They should pop off like a spark plug wire. Find a suitable ground and place the positive lead on the glow plug. It should read approx 1.0 ohm resistance give or take 0.5 ohm. If you find that you have one or more plugs with either high resistance, no resistance, or a large variation between the 4 plugs, then you have likely diagnosed the problem and the plugs need to be replaced. If they are all the same or within .1 or .2 ohms, then the plugs are not the problem.

Beyond that, make sure you have done the obvious and check the fuses. The relay may need to be replaced as well. Good luck.

HI. Usually, when this light illuminates, it will signal that one, or more of the glow plugs are malfunctioning. I recommend to test all glow plugs, so that you may isolate the defective plug.

Above the Relay Panel is the Auxiliary Relay Panel. Has thirteen positions in it.
6 across the top, 7 across the bottom.

Across the bottom the Glow Plug Relay is the fourth one over from the left. It is Number 10.

I have a 1997 ford F350 WITH A 7.3L DIESEL, it turns over but will not start. My wail to start light or other indicator lights do not come on when I turn on the key.


The first thing to do is locate the owner manual.

Look for the glow plug relay MAIN FUSE location.

The glow plug portion of your van is not working.

This difficulty scale from 1 to 10 is a 9.

You will need a DVM and tool undo the cables to each glow plugs.

It's a 1 to 2 hours troubleshooting job.

I'm going to fire off a quick list

====
Check / replace blown glow plug relay main fuse
====

Disconnect each center nut of the glow plug wire. PLEASE CHECK ONE AT A TIME.

Read the resistance between the center of the glow plug and the metal base of the plug.

Please take good note on each glow plug resistance reading.

MAKE SURE all cables are put back and tighten properly.

Compare the resistance on all cylinders.

OPEN/high resistance is bad glow plug.

In general 3 ohm or less is OK.

You should buy one and use its value as baseline.

===

Glow plug relay can be bad.

You will need the VOM and a friend to turn the key.

Check the voltage to each glow plugs. It should be 12.6-13.6 volt.

Be careful,the plugs will get HOT.

Compare the voltage on each cylinders.

====
So the problem can be combination of

glow plug relay

glow plug relay main fuse

glow plugs

ignition switch is unlikely but I'm going to list it anyway.

Once again,this is a difficult and time consuming job. I will ask a friend to help out,

Good luck.
