DTC Fault Trigger Conditions






Pinpoint Test

1. CHECK THE OPERATION OF THE STEERING WHEEL CONTROLS

1. Operate the infotainment system in radio tuner (AM/FM (Amplitude Modulation/Frequency Modulation)) mode.

2. Press the VOICE switch on the steering wheel controls.

Does the infotainment system enter voice recognition mode?








2. CHECK THE MICROPHONE CIRCUITS TO THE APIM (Accessory Protocol Interface Module) FOR A SHORT TO VOLTAGE

1. Ignition OFF.

2. Disconnect: APIM (Accessory Protocol Interface Module).

3. Ignition ON.

4. Measure:





Is any voltage present?








3. CHECK THE MICROPHONE CIRCUITS TO THE APIM (Accessory Protocol Interface Module) FOR A SHORT TO GROUND

1. Ignition OFF.

2. Disconnect: Microphone.

3. Measure:





Are the resistances greater than 10,000 ohms?








4. CHECK THE MICROPHONE CIRCUITS TO THE APIM (Accessory Protocol Interface Module) FOR AN OPEN

1. Measure:





Are the resistances less than 3 ohms?








5. CHECK THE MICROPHONE CIRCUITS TO THE APIM (Accessory Protocol Interface Module) FOR A SHORT TOGETHER

1. Measure:





Is the resistance greater than 10,000 ohms?








6. ISOLATE THE MICROPHONE

1. Install a new microphone. REFER to Microphone .

2. Test the voice recognition for normal operation.

Is the voice recognition functioning correctly?








7. CHECK FOR CORRECT APIM (Accessory Protocol Interface Module) OPERATION

1. Disconnect and inspect the APIM (Accessory Protocol Interface Module) connector.

2. Repair:

- corrosion (install new connector or terminals- clean module pins)
- damaged pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

3. Reconnect the APIM (Accessory Protocol Interface Module) connector. Make sure it seats and latches correctly.

4. Wait 2 minutes for the APIM (Accessory Protocol Interface Module) to re-initialize.

5. Operate the system and determine if the concern is still present.

Is the concern still present?
