Verify the SSN is not in SPH by checking if the SSN is on Quickserve OnlineTM.
Log on to quickserve.cummins.com.
Enter SSN in search bar.
If prompt is ESN not found, put in an Answers help ticket to request for SSN to be added into SPH.
If prompt is that ‘ESN has been updated’, continue to next step.
Verify the connectivity module is working.
Turn on low voltage, do not turn on key switch.
If a solid green light is present on the module, replace the connectivity module.
After connectivity module is replaced, allow it to update before verifying the issue is resolved.
i. Turn low voltage on and key off for about 1-2 hours for the updates to be completed.
ii. Verify the data is present on the telematics portal after a key cycle.
If the green light is blinking, continue to the next step.
Verify the connections/harness to the connectivity module are not loose.
Reference the wiring harness diagram to inspect every connection point between connectivity module and SCM.
Verify the harness/CAN is properly terminated.
Verify the resistance of the CAN is 60 ohms, with both resistors connected.
Verify the resistance of the CAN is 120 ohms if one resistor is connected.
If issue persists, follow technical escalation process.
