Thoroughly inspect the P1 connector, and the lamp connections. Refer to service Troubleshooting, "Electrical Connectors - Inspect".
Perform a 45 N (10 lb) pull test on each of the wires that are associated with the indicator lamps.
Check the allen head screw on each ECM connector for the proper torque. Refer to service Troubleshooting, "Electrical Connectors - Inspect".
Check the harness for abrasions and for pinch points from the battery to the ECM.Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted. The harness and wiring are free of corrosion, of abrasion, and of pinch points.Results:
OK - The connectors and wiring appear to be OK. Proceed to Test Step 2.
Not OK - There is a problem in the connectors and/or wiring.Repair: Repair the connectors or the harness and/or replace the connectors or the harness. Ensure that all of the seals are correctly in place and ensure that the connectors are completely coupled.If applicable, use Caterpillar Electronic Technician (ET) to perform a wiggle test.Verify that the repair eliminates the problem.STOPTest Step 2. Check for Normal Operation of the Suspect Lamp
Turn the keyswitch to the ON position and monitor the indicator lamps.
The diagnostic lamps will illuminate for a minimum of two seconds after the power is returned to the ECM. The lamp will then turn off.
Turn the keyswitch to the OFF position.Expected Result:The suspect lamp illuminates and the lamp turns off per the above description.Results:
OK - The suspect lamp illuminates and the lamp turns off per the above description.Repair: The diagnostic lamps appear to operating correctly at this time. There may be an intermittent electrical problem in the harness or in a connector. If an intermittent problem is suspected, refer to service Troubleshooting, "Electrical Connectors - Inspect".STOP
Not OK - The suspect lamp does not illuminate or the suspect lamp does not turn off per the above description. Proceed to Test Step 3.Test Step 3. Measure the Voltage at the Lamp Socket
Turn the keyswitch to the ON position.
Use the Cat ET to select the "override" function in order to switch individual lamps ON and OFF.Note: The "Override" function is contained in the "Diagnostics" menu of the Cat ET.
Measure the voltage at the suspect lamp socket.Expected Result:The voltage is between 12.0 VDC and 24.0 VDC.Results:
OK - The voltage is between 12.0 VDC and 24.0 VDC.Repair: Replace the bulb. Verify that the repair eliminates the problem.STOP
Not OK - The voltage is not between 12.0 VDC and 24.0 VDC. Proceed to Test Step 4.Test Step 4. Test the Lamp Circuit
Turn the keyswitch to the OFF position.
Disconnect the P1 connector.
Temporarily disconnect the wire from the P1 connector for the suspect lamp.
Temporarily disconnect the wire from one of the +Battery connections on the P1 ECM connector.
Fabricate the jumper wire with a suitable pin for the P1 connector.
Install one end of the jumper wire into the P1 connector socket for the suspect lamp. Connect a test lamp between the +Battery wire and the jumper wire.
Reinstall the P1 connector to the ECM.
Turn the keyswitch to the ON position.
Use Cat ET to select the override function in order to switch individual lamps ON and OFF.Note: The "Override" function is contained in the "Diagnostics" menu of the Cat ET.Expected Result:The test lamp will illuminate.Results:
OK - The test lamp illuminated. The ECM is operating correctly.Repair: There is a fault in the wiring or the lamp. Repair the wiring or the lamp, as required. Verify that the repair eliminates the fault.STOP
Not OK - The test lamp did not illuminate.Repair: Temporarily connect a test ECM. The test ECM must be programmed with the same parameters as the suspect ECM. Check the operation of the indicator lamp when the test ECM is installed. If the fault is resolved with the test ECM, then reconnect the suspect ECM. If the fault returns with the suspect ECM, then replace the suspect ECM. Refer to service Troubleshooting, "ECM - Replace".
