Diagnostic Trouble Codes for the Indicator Lamps
J1939 Code Description Notes
623-5 Red Stop Lamp : Current Below Normal The Electronic Control Module (ECM) detects a low current condition in the circuit for the shutdown lamp.
623-6 Red Stop Lamp : Current Above Normal The ECM detects a high current condition in the circuit for the shutdown lamp.
624-5 Amber Warning Lamp : Current Below Normal The ECM detects a low current condition in the circuit for the warning lamp.
624-6 Amber Warning Lamp : Current Above Normal The ECM detects a high current condition in the circuit for the warning lamp.
1081-5 Engine Wait to Start Lamp : Current Below Normal The ECM detects a low current condition in the circuit for the wait to start lamp.
1081-6 Engine Wait to Start Lamp : Current Above Normal The ECM detects a high current condition in the circuit for the wait to start lamp.
3697-5 Particulate Trap Lamp Command : Current Below Normal The ECM detects a low current condition in the circuit for the Diesel Particulate Filter (DPF) lamp.
3697-6 Particulate Trap Lamp Command : Current Above Normal The ECM detects a high current condition in the circuit for the DPF lamp.
3698-5 Exhaust System High Temperature Lamp Command : Current Below Normal The ECM detects a low current condition in the circuit for the High Exhaust System Temperature (HEST) lamp.
3698-6 Exhaust System High Temperature Lamp Command : Current Above Normal The ECM detects a high current condition in the circuit for the HEST lamp.
3702-5 Diesel Particulate Filter Active Regeneration Inhibited Status : Current Below Normal The ECM detects a low current condition in the circuit for the DPF disabled lamp.
3702-6 Diesel Particulate Filter Active Regeneration Inhibited Status : Current Above Normal The ECM detects a high current condition in the circuit for the DPF disabled lamp.
5099-5 Engine Oil Pressure Low Lamp Data : Current Below Normal The ECM detects a low current condition in the circuit for the low oil pressure lamp.
5099-6 Engine Oil Pressure Low Lamp Data : Current Above Normal The ECM detects a high current condition in the circuit for the low oil pressure lamp. The Engine Control Module (ECM) provides nine outputs that can be used to illuminate indicator lamps. If applicable, some of the outputs can be programmed to a J1939 device.Each J1/P1 output is a low side driver.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.Table 2 provides information on the typical lamp outputs.

Troubleshooting Test Steps Values Results
1. Test the Circuit
A. Turn the keyswitch from OFF to ON in order to test the circuit.
Watch the lamp during the test.
Circuit test
Result: The lamp does not illuminate.
Troubleshoot any active codes before continuing with this procedure.
Proceed to Test Step 2.
Result: The lamp illuminates.
There is a problem with the wiring if the problem is intermittent. Troubleshoot the wiring by referring to the electrical schematic for the application.
STOP
2. Check the Bulb
Replace the bulb with a bulb that is known to be good. Test the circuit again.
Bulb
Result: The lamp illuminates. The problem is resolved.
STOP
Result: 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
Check the wiring for an open circuit. Pay particular attention to possible problems with electrical connectors.
Lamp wiring
Result: There is an open circuit in the wiring for the lamp.
Make the necessary repairs.
STOP
Result: The wiring for the lamp is OK.
