Here is the instruction show you guide on how to solve QSK60 G CM2350 Start Enable Device 1 Circuit (Ether Injection) – Root Cause Not Known.
What You Need?
Cummings inline6 diagnostic adapter
CODE
Fault Code: 1373
PID: S237
SPN: 626
FMI: 11/11
LAMP: Maintenance
Reason
An open or short circuit has been detected on the ether injection circuit.
EFFECT
Ether start functionality will be disabled.
Engine may not start or may be difficult to start
Circuit Description
The ether injection circuit is a device used by the engine to control the ether injection operation. The ether injection circuit utilizes a Pulse Width Modulated (PWM) signal. A PWM signal is pulsed voltage signal between 0-VDC and system voltage. The frequency of the pulsed voltage signal is dependent on the application requirement.
Component Location
The control solenoid location varies by OEM. Refer to the appropriate OEM service manual to determine the location.
Conditions for Running the Diagnostics
This diagnostic runs when the keyswitch is in the ON position and when the pulse width modulated (PWM) device is getting energized or de-energized. In some cases, the diagnostics can also run at some fixed intervals.
Conditions for Setting the Fault Codes
The ether injection circuit pulse width modulated (PWM) signal voltage was greater than 0-VDC when the PWM signal was turned off by the ECM.
The ether injection circuit pulse width modulated (PWM) signal was not at system voltage when the PWM signal was turned ON.
Action Taken When the Fault Code is Active
The ECM illuminates the white MAINTENANCE lamp or flashes the amber CHECK ENGINE lamp, indicating a maintenance condition, immediately after the diagnostic runs and fails.
The ether injection operation will be disabled.
Conditions for Clearing the Fault Code
To validate the repair, perform a key cycle, and leave the key in the ON position for 1 minute.
The fault code status displayed by the recommended Cummings electronic service tool or equivalent will change to INACTIVE immediately after the diagnostic runs and passes.
The ECM will turn off the flashing amber CHECK ENGINE lamp / MAINTENANCE lamp immediately after the diagnostic runs and passes.
The “Reset All Faults” command in the recommended Cummings electronic service tool or equivalent can be used to clear active and inactive faults.
