Circuit/System Testing
- Ignition OFF, disconnect the X2 harness connector at the K73 Telematics Communication Interface Control Module and the X1 harness connector at the A11 Radio.
- Ignition ON.
- Test for less than 1 V between the signal circuits listed below and ground:
- voice recognition signal circuit A11 Radio X1 terminal 4
- voice recognition low reference circuit A11 Radio X1 terminal 5
- If 1 V greater
Repair the short to voltage on the circuit.
- If less than 1 V
- Ignition OFF.
- Test for infinite resistance between the circuits listed below and ground:
- voice recognition signal circuit A11 Radio X1 terminal 4
- voice recognition low reference circuit A11 Radio X1 terminal 5
- If less than infinite resistance
Repair the short to ground on the circuit.
- If infinite resistance
- Test for less than 5 Ω between the terminals listed below:
- A11 Radio X1 terminal 4 and the K73 Telematics Communication Interface Control Module X2 terminal 6
- A11 Radio X1 terminal 5 and the K73 Telematics Communication Interface Control Module X2 terminal 12
- If 5 Ω greater
Repair the open/high resistance in the circuit.
- If less than 5 Ω
- Replace the A11 Radio. Connect all harness connectors.
- Begin voice recognition for the radio and clearly speak one of the available commands.
- Verify the infotainment system responds correctly to the command.
- If the infotainment system does not respond correctly to the command
- Clearly speak a different command.
- Verify the infotainment system responds correctly to the command.
- If the infotainment system does not respond correctly to any commands, replace the K73 Telematics Communication Interface Control Module.
- If the infotainment system responds correctly to the command
- All OK
NOTE:
Refer to the Navigation System Owners Manual for voice recognition use and commands.
