1081100 Cool Engine Shutdown

then start to heat up, essentially cooking the oil which causes premature bearing
failure. By allowing the turbocharger to slow down to a safe RPM, this bearing failure
can be prevented. An efficient means of gauging a safe time to turn the engine off is by
the exhaust temperature.
A good temperature range to go by is when a turbocharger is below 400°F (with the
thermocouple mounted post-turbo) it is safe to turn off the engine. The further away
the probe is away from the turbocharger, the shut-off temperature should be lower. If
the thermocouple is mounted pre-turbo, then the shut-off temperature can be higher.
How does the COOL ENGINE SHUTDOWN work?
The CES module utilizes the data being transmitted between the X-Monitor controller
and display to constantly monitor the exhaust temperature. When the key is turned off
and the exhaust temperature is above the shutdown setting, the CES module will keep
power supplied to the ECM/PCM, which in turn will keep the engine running until the
temperature falls below the setting.
Precautions
The CES will not lock the doors or set the alarm. With most vehicles, once you shut
the door you can use the keyless remote or key to lock the doors.
Most OEM and aftermarket alarms will have to be activated after the CES has
shutdown the engine. Due to the wide variety of the alarms and immobilizers, it is best
to test the system(s) thoroughly to ensure proper procedures of activation or use in
conjunctions with the CES.
Proper parking procedures should be adhered to before leaving the vehicle including
the engagement of the parking brake.
Children or animals should not be left
unattended in the vehicle while the CES is keeping the vehicle running.
Safety Features
The CES module has a few safety features built in that the driver should be aware of.
If for some reason the exhaust temperature does not fall below of shutdown setting
within five (5) minutes from the key being turned off, the CES will automatically
shutdown the engine.
The CES module is also designed to monitor the vehicle's hydraulic brakes when it is
connected to the brake pedal switch via the Brake Pedal terminal on the module.
While the CES module is keeping the engine alive (ignition key turned off and exhaust
temperature above the shutdown setting), if the brake pedal is depressed the CES will
