SENSOR GP-PRESSURE 3587306 - Caterpillar

Procedure For Initialization
This procedure causes the initialization to occur on any main display module. Initialization requires that the main display module to be powered up with a valid harness code. The valid harness code must be different than the harness code when the module was last powered down. For a list of valid harness codes, see the table for Machine Codes in System Operation, "Harness Code Mode".
Code input configuration.
Turn the key start switch to the OFF position.
Determine whether the harness code inputs are hard wired in the machine harness or accessible at a harness code plug. Use the Electrical System Schematic in the Service Manual for the machine.Expected Result: There is a harness code plug.Results:
YES - There is a harness code plug. Remove the harness code plug. Proceed to 3.
NO - The harness code inputs are hard wired in the machine harness. Proceed to 2.
Hard wired procedure.
Disconnect the machine harness from the main display module.
At the machine harness connector for the main display module, remove the wire for one of these contacts (3, 6, 12, 16, 22 or 31). Choose a contact that is connected to ground. Note: If a ground wire is not available, on any of the mentioned ECM contacts, then install a jumper wire between contact 2 (ECM ground) and contact 3 and repeat 2.b.
With tape, secure the removed connector contact out of the way.
Reconnect the machine harness to the main display.Results:
CONTINUE - Proceed to 3.
Reconnection and verification.
Turn the disconnect switch and the key start switches to the ON position.
Various indicators in the Caterpillar Monitoring System display area will illuminate. Wait 10 seconds.
Turn the key switch to the OFF position.
Depending on the previous procedure that was performed, either reinstall the harness code plug (from "Code input configuration") or reinstall the ground connector contact (from "Hard wired procedure").
Make sure that the main display module successfully completes the self test, see Testing and Adjusting, "System Self Test".
Check the machine code. See System Operation, "Harness Code Mode".Expected Result: The display module has successfully completed the self test.Results:
OK - The display module successfully completed the self test. STOP.
NOT OK - The display module did not complete the self test. Exit this procedure. Determine the cause of the failure and repeat "Initialization". STOP.
