BLUETOOTH Module (Tel)

CAUTION: Diagnosis by substitution from a donor vehicle is NOT  acceptable. Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
NOTE: If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval program is in operation, prior to the installation of a new module/component.
NOTE: Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system).
NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
NOTE: Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.
NOTE: If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.

The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Bluetooth Module, for additional Diagnosis and Testing information refer to the relevant Diagnosis and Testing. For additional information, refer to: Cellular Phone (415-00 Information and Entertainment System - General Information, Diagnosis and Testing).

DTC  Description  Possible Causes  Action 
B1D79-84 Microphone Input - Signal below allowable range
  • The 'Receive Audio over MOST Test' failed and means that the audio received at the microphone detection point is too low
  • Microphone fault
  • Harness/connector fault
  • Integrated head unit (IHU) fault
Check the operation of the microphone. Refer to the electrical circuit diagrams and check the microphone (MIC) circuits. Renew/repair as necessary. Refer to the warranty policy and procedures manual if a module is suspect.
U1A00-88 Private Communication Network - Bus off
  • Internal communications failure
Clear the DTC and retest. If the problem persists, renew the Bluetooth Module. Refer to the warranty policy and procedures manual if a module is suspect.
U2001-9A Reduced System Function - Component or system operating conditions
  • Bluetooth error - system over-temperature
Allow the system to cool, clear the DTC and check /monitor for re-occurrence. If DTC re-occurs suspect the module. Check and install a new module as required. Refer to the Warranty Policy and Procedures manual if a module is suspect.
U201A-54 Control Module Main Calibration Data - Missing calibration
  • Local configuration file is missing (not loaded) in the control module
Configure the module using the manufacturers approved diagnostic system (file download may take several minutes).
U3000-44 Control module - Data memory failure
  • Bluetooth Module RAM fault (data memory failure leading to possible corrupt local configuration file)
Configure the module using the manufacturers approved diagnostic system and download the local configuration file. Clear the DTC and retest. If the problem persists, renew the Bluetooth Module. Refer to the warranty policy and procedures manual if a module is suspect.
U3000-45 Control module - Program memory failure
  • Bluetooth Module ROM fault (data memory failure leading to possible corrupt local configuration file)
Configure the module using the manufacturers approved diagnostic system and download the local configuration file. Clear the DTC and retest. If the problem persists, renew the Bluetooth Module. Refer to the warranty policy and procedures manual if a module is suspect
U3000-54 Control module - Missing calibration
  • MOST not configured correctly - incorrect voice language installed
Check and amend the Car Configuration File in the Information and Entertainment Control Module using the manufacturer approved diagnostic system.
U3000-56 Control module - Invalid/incomplete configuration
  • One or more of the received car configuration file (CCF) data parameters is deemed to be invalid
Check and amend the Car Configuration File using the manufacturer approved diagnostic system.
U3003-16 Battery Voltage - Circuit voltage below threshold
  • Battery voltage below threshold
Check vehicle battery and charging system. Refer to the relevant section in the workshop information. Refer to the electrical circuit diagrams and check the power supply circuits to the module.
U3003-17 Battery Voltage - Circuit voltage above threshold
  • Battery voltage above threshold
Check vehicle battery and charging system. Refer to the relevant section in the workshop information. Refer to the electrical circuit diagrams and check the power supply circuits to the module.
