(73) Stop lamp Test Step 1. Inspect Electrical Connectors and Wiring
Turn the keyswitch to the OFF position.
Thoroughly inspect the P1 connector and the lamp connections. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the P1 connector that are associated with the indicator lamps.
Check the harness for abrasions and for pinch points from the battery to the ECM. Results:
OK - Proceed to Test Step 2.
Not OK - 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 correctly connected.Verify that the repair eliminates the fault.STOPTest Step 2. Inspect the Lamp
Disconnect the lamp from the harness. Inspect the lamp in order to determine if the lamp has failed.
Measure the resistance across the two terminals of the lamp. If the resistance is more than 2000 Ohms, the bulb has failed. Results:
The lamp has less than 2000 Ohms resistance. - The lamp appears to be operating correctly at this time. Proceed to Test Step 3.
The lamp does not have less than 2000 Ohms resistance - Repair: Replace the lamp. Verify that the repairs have eliminated the fault.STOPTest Step 3. Measure the Input to the Lamp at the Lamp Socket
Turn the keyswitch to the ON position.
Measure the voltage between the lamp socket and a suitable ground. Results:
The voltage is between 12.0 VDC and 24.0 VDC. - Repair: Replace the bulb.Verify that the repair eliminates the fault.If the fault persists, measure the resistance across the two terminals of the lamp. If the resistance is more than 2000 Ohms, the replacement bulb has failed. Replace the bulb and repeat the test.If the fault persists, proceed to Test Step 4.
The voltage is not between 12 VDC and 24 VDC - The fault is in the battery supply wiring to the lampRepair: Replace the faulty wiring.Verify that the repair eliminates the fault.STOPTest Step 4. Check the Wiring Between the Lamp and the ECM
Turn the keyswitch to the OFF position.
Disconnect the P1 connector.
Use a suitable multimeter to measure the resistance between the suspect lamp connector and the appropriate socket on the P1 connector. Results:
The measured resistance is greater than 2 Ohms - The fault is in the wiring between the suspect lamp and the ECMRepair: Replace the faulty wiringVerify that the repair eliminates the fault.STOP
The measured resistance is less than 2 Ohms - Repair: Perform the following repair:
Make sure that the latest flash file for the application is installed in the ECM. Refer to Troubleshooting, "Flash Programming".
Contact the Technical Communicator at a Cat dealer. Note: This consultation can greatly reduce the repair time.
If the Technical Communicator recommends the use of a replacement ECM, install a replacement ECM. Refer to Troubleshooting, "Replacing the ECM".
Use the electronic service tool to recheck the system for active diagnostic codes.
If the fault is resolved with the replacement ECM, reconnect the suspect ECM.
If the fault returns with the suspect ECM, replace the ECM.
Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault. STOP
