Information:
System Operation Description:The Engine Control Module (ECM) provides nine outputs that can be used to illuminate indicator lamps. The Caterpillar Electronic Technician (ET) can be used to program each output to a specific J1/P1 terminal. Some of the outputs can be programmed to a J1939 device.Each J1/P1 output is a high side driver or a low side driver.High Side Driver - The ECM provides an output voltage that is approximately equal to the battery voltage in order to activate the lamp.Low Side Driver - The ECM provides a connection to ground in order to activate the lamp.J1939 Device - The ECM sends digital data on the J1939 data link in order to control the lamp. The data is converted to a signal for the lamp by a J1939 device that is provided by the OEM.Table 1 provides information on the lamp outputs. There are no diagnostic codes for these outputs.

Testing 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 Caterpillar Electronic Technician (ET) can activate every lamp except the check engine lamp. The special tests activate the lamps for all programming options.Test Step 1. Test the CircuitIf 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.Expected Result:The lamp does not illuminate.Results:
Yes - The lamp does not illuminate. Proceed to Test Step 2.
No - The lamp illuminates.Repair: There is a problem with the vehicle's wiring if the problem is intermittent. Troubleshoot the wiring by referring to the vehicle's wiring information.STOPTest Step 2. Check the BulbReplace the bulb with a bulb that is known to be good. Test the circuit again.Expected Result:The lamp illuminates.Results:
Yes - The lamp illuminates. The problem is resolved.STOP
No - The lamp does not illuminate. The bulb is OK.Repair: The +Battery or the ground is not present at the lamp. Obtain wiring information for the vehicle.Troubleshoot the wiring by referring to the vehicle's wiring information 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.Test Step 3.
