Table 1
Diagnostic Trouble Codes for Engine Overspeed
J1939 Code CDL Code Code Description
(code descriptions may vary) Comments
190-15 E362 (1) Engine Overspeed Warning - Level 1 The engine has exceeded the value that is programmed into the Electronic Control Module (ECM) for 0.6 seconds.
There are no diagnostic trouble codes for the speed/timing sensors.
The engine has been running for at least 3 seconds.
190-0 E362 (3) Engine Overspeed Warning - Level 3 The engine has exceeded the value that is programmed into the Electronic Control Module (ECM) for 0.6 seconds.
There are no diagnostic trouble codes for the speed/timing sensors.
The engine has been running for at least 3 seconds.
The engine may shut down. The ECM limits the flow of fuel in order to prevent the engine speed from exceeding the value that is programmed into the ECM. When the engine speed has dropped to less than the value that is programmed into the ECM, the 190-x (E362) code will be reset.If the engine speed exceeds the value that is programmed into the ECM, the ECM illuminates the warning lamp and a 190-x (E362) code is logged. Factory passwords are required in order to clear the code. No troubleshooting is required.The history of engine overspeeds can be viewed on the electronic service tool.Probable Causes
Proceeding down steep grades (if applicable)
Diagnostic codes
Turbocharger
Combustible gases or liquid in the Intake airRecommended Actions
Note: The procedures have been listed in order of probability. Complete the procedures in order.

Troubleshooting Test Steps Values Results
1. Proceeding Down Steep Grades (If Applicable)
Engaging the engine brakes on a steep grade may be necessary. Not all applications have engine brakes.
A. Make sure that the operator understands the correct operation of the machine while using the engine brakes.
Steep grades
Result: Steep grades are the cause of the overspeed.
Repair: Control the engine speed during steep grades.
Result: Steep grades are not the cause of the overspeed.
Proceed to Test Step 2.
2. Diagnostic Codes
A. Download the Warranty Report and the Product Status Report with Histograms before performing any troubleshooting or clearing any diagnostic codes.
Note: The downloaded information will be required by the Dealer Solutions Network (DSN) if troubleshooting assistance is needed.
B. Use the electronic service tool to check for active or logged codes.
Diagnostic codes
Result: A diagnostic code is not active or logged.
Return the unit to service.
Result: At least one of the diagnostic codes listed in Table 1 is active or recently logged.
Proceed to Test Step 3.
3. Turbocharger
Note: The turbocharger that is installed on the engine is nonserviceable items. If any mechanical fault exists, then the faulty turbocharger must be replaced.
A. Check for any oil that may be leaking into the intake air.
Turbocharger
Result: The turbocharger is leaking oil into the intake air.
Repair: Replace the faulty turbocharger.
Result: The turbocharger is not leaking oil into the intake air.
Proceed to Test Step 4.
4. Combustible Gases or Liquid in the Intake Air
A. Check for combustible gases in the surrounding atmosphere.
B. Check for combustible liquid in the air intake.
Air quality
Result: The atmosphere has combustible gases.
Repair: Do not operate the engine in an environment with combustible gases.
Result: There
