63718-ZY3-000 Honda SEAL A, COVER (LOWER) (Honda Code 6993174).

Engine Monitoring
The Electronic Control Module (ECM) monitors the operating parameters of the engine. The ECM will generate an event code if a specific engine parameter exceeds an acceptable range that is defined by the engine monitoring system. For information on the engine monitoring system, refer to Troubleshooting, "Engine Monitoring System".Cross-Reference Information for Event Codes
Event codes are generated when abnormal operating conditions exist. The event codes are cross-referenced with the appropriate procedure that can be used to troubleshoot the code.

Engine Automatic Start Failed An attempt from the automatic start system failed to start the engine due to an overcrank condition. The starting attempt has exceeded the time that is programmed for the "Cycle Crank Time" parameter. Activation of this code latches an engine shutdown condition. The power to the ECM must be cycled prior to any additional attempts to start the engine. For troubleshooting information that is related to this diagnostic code, refer to Troubleshooting, "Engine Cranks, but Does Not Start".

3607-31
Engine Emergency Shutdown Indication The ECM has detected the activation of the emergency stop switch. The ECM disables ignition and the ECM closes the gas shutoff valve. Determine the reason for the emergency stop shutdown and resolve the issue. Reset the emergency stop switch. Return the engine to service.
For information that is related to troubleshooting this code, refer to Troubleshooting, "Engine Shutdown Occurrence".
5272-31
Unexpected Engine Shutdown The ECM has detected that the engine is in the run mode and the engine speed falls below 100 rpm. The ECM disables ignition and the ECM closes the gas shutoff valve. The engine control switch must be cycled prior to restarting the engine. Determine the reason for the unexpected shutdown and resolve the issue. Return the engine to service. For information that is related to troubleshooting this code, refer to Troubleshooting, "Engine Shutdown Occurrence".
