Telematics Remote Engine Starter/Res Air Conditioner Does Not Function

Probable cause:

No contract agreement, out of service area, server side malfunction, DCM malfunction, antenna malfunction, smartphone malfunction

CAUTION:

After the DCM is replaced, registrations of CommCheck and immobilizer system are required. Ref. to ENTERTAINMENT & MONITORING>TELEMATICS SYSTEM>OPERATION>REGISTRATION (COMM CHECK) .
Before performing diagnosis, refer to "CAUTION" in "General Description". Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>GENERAL DESCRIPTION>CAUTION .

CHECK THE SUBSCRIPTION STATUS .

Is the data [TRUE]?

Yes: Go to 2.

No :
- The user does not have a service subscription; therefore, it is not a failure.
- When the user's service subscription is not set to [TRUE], set the provisioning.
When the setting does not change to [TRUE] even after setting the provisioning again, replace the DCM. Ref. to ENTERTAINMENT & MONITORING>DATA COMMUNICATION MODULE .

Ref. to KEYLESS ACCESS WITH PUSH BUTTON START (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST . Ref. to BODY CONTROL (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST .

CHECK THE COMMUNICATION ENVIRONMENT OF THE USER'S SMARTPHONE .
Check that the user's smartphone can be connected to the Internet.

Can it be connected to the Internet?

Yes: Go to 4.

No: The user's smartphone or the Internet environment has a problem.
CHECK REMOTE ENGINE STARTER FUNCTION .
Check that the remote engine starter operates by the smartphone.

Does it operate?

Yes: Currently no failure is found. If the remote engine starter did not operate, the user's Internet environment (radio waves, etc.) possibly had a problem.

No: Go to 5.
CHECK THE CURRENT RECEIVED SIGNAL STRENGTH (CHECK THE DATA MONITOR) .
Using the Subaru Select Monitor, check the following items in the [Data monitor] of [Telematics]. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DATA MONITOR .
- Signal Strength
Is the data 26 [%] or more?

Yes: Go to 6.

No: Check the telematics antenna.
CHECK STARLINK SERVER .
Verify that there was no server outage that coincides with the day/time the customer reported that the issue occurred. (Refer to STARLINK Server Maintenance/Down Report under Reports and Starlink section in Subarunet.)

Was there server outage that coincides with the day/time when the issue occurred?

Yes: Currently no failure is found. When the user had a problem, there was a failure with Starlink Server.

No: If no outage exists for that time frame, it is possible that there was environmental interference (radio waves, etc.) when the user performed the operation. No further actions are recommended.
