ADAPTER AS-DRAIN 4C8563 - Caterpillar

System Operation Description:Use this procedure if any of the following diagnostic codes are present:
1-11 Cylinder #1 Injector current fault
2-11 Cylinder #2 Injector current fault
3-11 Cylinder #3 Injector current fault
4-11 Cylinder #4 Injector current fault
5-11 Cylinder #5 Injector current fault
6-11 Cylinder #6 Injector current faultPerform this procedure under conditions that are identical to the conditions that exist when the problem occurs. Typically, problems with the injector solenoid occur when the engine is warmed up and/or when the engine is under vibration (heavy loads).The following background information is related to this procedure:The engines use Hydraulic Electronic Unit Injectors that are hydraulically actuated and electronically energized. The solenoid is mounted on top of the fuel injector body.The injectors can be individually cut out to aid in troubleshooting misfire problems. Use the "Cylinder Cutout Test" to disable individual injectors.The injector solenoids can also be actuated without running the engine in order to check the operation of the solenoids. Use the "Injector Solenoid Test" to perform this function.Note: The "Injector Solenoid Test" will not help find leaks in the high pressure oil system.

P2 ECM connectorTest Step 1. Inspect Electrical Connectors and Wiring
Electrical shock hazard. The electronic unit injector system uses 90-120 volts.
Turn the key switch to the OFF position. A strong electrical shock hazard is present if the key switch is not turned OFF.
Thoroughly inspect the J2/P2 ECM connector and the J300/P300 valve cover connector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector and the J300/P300 valve cover connector that are associated with injector solenoids.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the J300/P300 valve cover connector in order to ensure the proper mating of the connector.
Check the harness and wiring for abrasion and for pinch points from the injectors to the ECM.Expected Result:All connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion or of pinch points.Results:
OK - Proceed to Test Step 2.
Not OK - Repair: Perform the following repair:Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.STOPTest Step 2. Check for Logged Diagnostic Codes
Connect the electronic service tool to the data link connector.
Turn the key switch to the ON position.
Check for logged diagnostic codes on the electronic service tool.Expected Result:One or more of the listed codes have been logged:
1-11 Cylinder #1 Injector current fault
2-11 Cylinder #2 Injector current fault
3-11 Cylinder #3 Injector current fault
4-11 Cylinder #4 Injector current fault
5-11 Cylinder #5 Injector current fault
6-11 Cylinder #6 Injector current faultResults:
Yes - Proceed to Test Step 4.
No - Proceed to Test Step 3.Test Step 3. Perform the "Cylinder Cutout Test"
Connect the electronic service tool to the data link connector.
When possible, put the truck on a dynamometer.
Start the engine.
