I have pcm on the screen how do i get rid of it

You need to say what model/year etc.

Cranks won't start , Did you check for spark ,fuel pressure ?
Radio Setup .Will the vehicle communicate with a scan tool ? Fuel an temp gauges not working are probably bad step motors inside the instrument cluster that controls the gauges . Where do the gauges read 0 or something else ?
Engine Coolant Temperature Gage
The IPC displays the engine coolant temperature as determined by the PCM. The body control module (BCM) receives a class 2 message from the PCM indicating the engine coolant temperature. The BCM converts the engine coolant temperature into a percent gage deflection. The IPC receives a message from the BCM via the serial peripheral interface (SPI) indicating the requested gage position. The engine coolant temperature gage defaults to 38°C (100°F) or below if:
?€¢
The PCM detects a malfunction in the engine coolant temperature sensor circuit.

?€¢
The BCM detects a loss of class 2 communications with the PCM.

?€¢
The IPC detects a loss of SPI communications with the BCM.

Fuel Gage
The IPC displays the fuel level as determined by the PCM. The body control module (BCM) receives a class 2 message from the PCM indicating the fuel level percent. The BCM converts the fuel level percent into a percent gage deflection. The IPC receives a message from the BCM via the serial peripheral interface (SPI) indicating the requested gage position. The fuel gage defaults to E (empty) if:
?€¢
The PCM detects a malfunction in the fuel level sensor circuit.

?€¢
The BCM detects a loss of class 2 communications with the PCM.

?€¢
The IPC detects a loss of SPI communications with the BCM.

When the fuel level is less than a pre-determined value, the low fuel indicator illuminates.
DTC P0462
The fuel level sensor changes resistance based on fuel level. The PCM monitors the signal circuit of the fuel level sensor in order to determine fuel level. When the fuel tank is full, the sensor resistance is high and the PCM senses a high signal voltage. When the fuel tank is empty, the sensor resistance is low and the PCM senses a low signal voltage. The PCM uses the signal circuit of the fuel level sensor in order to calculate the total remaining fuel in the tank. The PCM sends the fuel level percent via the class 2 serial data circuit to the body control module (BCM). The BCM converts this data and sends a fuel gage percent deflection to the IPC via the serial peripheral interface (SPI) in order to control the fuel gage. The fuel level information is also used for misfire and EVAP diagnostics.

Have
For the DE 100 series radio, complete the following procedure, using a scan tool, in order to properly set up communication:

1. At the Main Menu screen, select: Diagnostics.
2. At the Vehicle Identification screen, select the following options:
?€¢
Model Year



?€¢
Passenger Car


3. At the System Selection Menu screen, select: Body.
4. At the Vehicle Identification screen, select the Platform type.
5. At the Body screen, select: Radio.
6. At the Radio screen, select: Special Functions.
7. At the Special Functions screen, select: Radio Setup.
8. At the Radio Setup screen, press ENTER. The following test will set up a new or existing radio.
9. Select one of the following options:
?€¢
USA/Canada



?€¢
Export


10. Press the ENTER key.
11. Verify that the scan tool displays "Test in Progress."
12. Verify that the scan tool displays "Test Completed Successfully."
13. Press EXIT on the scan tool.

Important: The radio set up will configure the following systems:
?€¢
LEARN VIN

?€¢
Diagnostic Trouble Codes

?€¢
Class 2 Radio Messages

?€¢
Country Code

?€¢
Chime Volume

?€¢
Chime Level

?€¢
12/24 Hour Clock

Without learning the VIN, the radio will display a locked message (LOC).
The radio setup procedure will also clear the following messages:
?€¢
CAL

?€¢
CAL ERR

?€¢
CALIBRATE

Is it charging properly should be at least 13.8 to 15.2 volts and amperage should max out at approx the alternators rating with full load.

Help us as little here friend !

'split screen' ? is it physically broken or do you have two identical screens appearing all the time ? Any description / info would be useful for us to help..

The ICP code just went through this a minute ago. Reset the Computer take off the positive terminal about 24 hours to reset the PCM that should get rid of the code. It's not one to ignore I hope you have fixed the problem.

Try adjusting distributor to 5 degrees after TDC.

you shouldve removed the lightbulb from the instrument cluster to remove the CEL.

Dealerships do it all the time for engine light\air bag lights.

as for info, you should go to LHForums.net

there are many people there that would be glad to help.

You will have to replace the PCM and it will have to be reprogrammed or your vehicle will not start.You will need to take your vehicle into the dealer and they will replace the PCM and program it in the vehicle.Hope this helps.Good luck.

U need the EPROM reflashed in the PCM to change the rev limiler setting.

There is really nothing you can do to get rid of the water mark.Unit considered to have water/moisture damage
