S1 CHECK FOR SCAN TOOL COMMUNICATION WITH THE APIM
- Carry out the network test using the scan tool.
- Does the APIM pass the network test?
- Yes: GO to S2 .
- No: REFER to MODULE COMMUNICATIONS NETWORK .
S2 CHECK THE SYNC SYSTEM OPERATION
NOTE: Carrying out a Master Reset returns all preference settings to the factory defaults, erases the phone book and call histories, and deletes any devices paired with the SYNC system.
- Connect: Multi-Media Interface Tester.
- Using the Multi-Media Interface Tester, test the audio output for the audio input jack, USB port, and Bluetooth connection.
- Do all of the SYNC inputs function correctly?
- Yes: The SYNC system is operating correctly at this time. CARRY OUT a SYNC system Master Reset. Refer to the Owner's Literature .
  REVIEW the SYNC system operation with the customer. If the customer device still does not operate correctly, the fault is with the customer device.
- No: If only some (but not all) of the inputs are inoperative, GO to SYMPTOM CHART - SYNC SYSTEM to diagnose the observed symptom.
  If all inputs are inoperative, GO to PINPOINT TEST X .
