1. CHECK THE SUBSCRIPTION STATUS  .

   Using the Subaru Select Monitor, check the following items in the [Data monitor] of [Telematics]. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DATA MONITOR .

   • Subscription Status

   Is the data [Subscribed]?

   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 [Subscribed], set the provisioning.

   When the setting does not change to [Subscribed] even after setting the provisioning again, replace the DCM. Ref. to ENTERTAINMENT & MONITORING>DATA COMMUNICATION MODULE .

2. CHECK THE LED  .
   1. Turn the ignition switch to ON.
   2. Check the LED condition.

   Does the RED LED go off and the GREEN LED illuminate?

   Yes:  The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis.

   NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.

   No:  Go to  3.

3. CHECK DTCS  .

   Read the DTC of [Telematics] using the Subaru Select Monitor. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .

   Is DTC B2A0A or B2A0B displayed?

   Yes:  Perform the diagnosis for the displayed DTC B2A0A or B2A0B. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)>DTC B2A0A RED LED CIRCUIT . Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)>DTC B2A0B GREEN LED CIRCUIT .

   No:  Go to  4.

4. CHECK THE LED ILLUMINATION CONDITION  .

   Using the Subaru Select Monitor, check the following items in the [Active Test] of [Telematics]. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>ACTIVE TEST .

   • RED LED Lighting
   • GREEN LED Lighting

   Is the LED turned on or off?
