P1 terminals for the J1939 data linkTesting the CircuitsThe ECM briefly activates the following lamps when the keyswitch is turned from OFF to ON:
"Amber Warning Lamp"
"Red Stop Lamp"
"DPF Lamp"
"High Exhaust System Temperature Lamp"
"Aftertreatment Disable Lamp" (if equipped)Special tests on the Cat ET can activate every lamp except the check engine lamp. The special tests activate the lamps for all programming options.

Troubleshooting Test Steps    Values    Results    
1. Test the Circuit
If the problem is related to one of the following lamps, turn the keyswitch from OFF to ON in order to test the circuit.
"Amber Warning Lamp"
"Red Stop Lamp"
"DPF Lamp"
"High Exhaust System Temperature Lamp"
"Aftertreatment Disable Lamp" (if equipped)
Otherwise, use the appropriate special test on Cat ET to test the circuit.
Watch the lamp during the test.
   
Circuit Test    
Result: Yes - The lamp does not illuminate.
Repair: Troubleshoot any active codes before continuing with this procedure.
Proceed to Test Step 2.
Result: No - The lamp illuminates.
Repair: There is a problem with the wiring if the problem is intermittent. Troubleshoot the wiring by referring to the electrical schematic.
   
2. Check the Bulb
A. Replace the bulb with a bulb that is known to be good. Test the circuit again.
   
Bulb    
Result: Yes - The lamp illuminates. The problem is resolved.
Result: No - The lamp does not illuminate. The bulb is OK.
The +Battery or the ground is not present at the lamp. Refer to the electrical schematic.
Troubleshoot the wiring by referring to the electrical schematic if the lamp output is programmed to a J1939 device.
Proceed to Test Step 3 if the lamp output is programmed to a J1/P1 terminal..
   
3. Troubleshoot the Wiring for the Lamp
A. Check the wiring for an open circuit. Pay particular attention to possible problems with electrical connectors.
   
Lamp Wiring    
Result: Yes - There is an open circuit in the wiring for the lamp.
Repair: Make the necessary repairs.
Result: No - The wiring for the lamp is OK.
Proceed to Test Step 4.
   
4. Test the ECM Output
A. Verify that the P1 connector is connected to the ECM.
B. Use Cat ET to determine the programming option for the lamp output. Then, refer to Illustration 1 in order to determine if the ECM output terminal is a high side ECM driver or a low side ECM driver.
C. Perform the following procedure if the P1 terminal is a high side driver:
Use 7X-1710 Multimeter Probes to connect a test lamp between the P1 terminal for the lamp and terminal P1-63 (-Battery).
D. Perform the following procedure if the P1 terminal is a low side driver:
Use 7X-1710 Multimeter Probes to connect a test lamp between the P1 terminal for the lamp and terminal P1-53 (Unswitched +Battery).
E. Turn the keyswitch to the ON to test the circuit. Watch the test lamp while the output is activated.
   
ECM Output    
Result: Yes - The test lamp illuminates. However, the indicator lamp does not illuminate.
Repair: Identify the cause of the wiring problem. Make the necessary repairs.
Result: No - The test lamp does not illuminate. There is a problem with the ECM.
Repair: Replace the ECM.
   Test Step 1. Results:
The procedure corrected the issue. - STOP
The procedure did not correct the issue. - Repair: Contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN). STOP
