RCC Does Not Operate
Probable cause:
No contract agreement, out of service area, server side malfunction, DCM malfunction, antenna malfunction, smartphone malfunction
Before performing diagnosis, refer to "CAUTION" in "General Description". Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>GENERAL DESCRIPTION>CAUTION .
- CHECK THE SUBSCRIPTION STATUS
.
- Turn the ignition switch to ON.
- Using the Subaru Select Monitor, check the following items in the [Data Monitor] of [Telematics]. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DATA MONITOR .
- Remote Engine Starter Active
Is the data [TRUE]?
Yes: Go to 2.
No: The user does not have a service subscription; therefore, it is not a failure.
- CHECK DTCS
.
Read the following DTCs using Subaru Select Monitor. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) . Ref. to KEYLESS ACCESS WITH PUSH BUTTON START (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) . Ref. to BODY CONTROL (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) . Ref. to P-HEV HYBRID POWERTRAIN CONTROL (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) . Ref. to AIR CONDITIONER (DIAGNOSTICS) (HEV)>DIAGNOSTIC TROUBLE CODE (DTC) .
- Telematics
- Keyless Access with Push Button Start
- Body Control
- Hybrid Powertrain Control
- Air Conditioner
Are any DTCs displayed?
Yes: Perform the diagnosis for the displayed DTCs. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST . Ref. to KEYLESS ACCESS WITH PUSH BUTTON START (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST . Ref. to BODY CONTROL (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST . Ref. to P-HEV HYBRID POWERTRAIN CONTROL (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST . Ref. to AIR CONDITIONER (DIAGNOSTICS) (HEV)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST .
No: Go to 3.
- 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 RCC FUNCTIONS
.
Check that RCC can be operated by the smartphone.
Does it operate?
Yes: Currently no failure is found. If the RCC 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.
