id0903e2101200

Possible DTC

AudioPilot^®2 function is inoperative

Using the M-MDS

U0155:00, U0010:88

Without using M-MDS (On-board diagnostic test mode)

16:Er12

Possible cause

•  Audio amplifier malfunction

•  Open or short circuit in AudioPilot^®2 signal wiring harness

•  Open or short circuit in AudioPilot^®2 microphone signal wiring harness

•  Open or short circuit in vehicle speed signal wiring harness (e. g., instrument cluster)

Note

•  Inspect the AudioPilot^®2 function while driving the vehicle and playing a CD.

Possible DTC	AudioPilot^®2 function is inoperative
Possible cause	• Audio amplifier malfunction • Open or short circuit in AudioPilot^®2 signal wiring harness • Open or short circuit in AudioPilot^®2 microphone signal wiring harness • Open or short circuit in vehicle speed signal wiring harness (e. g., instrument cluster) Note • Inspect the AudioPilot^®2 function while driving the vehicle and playing a CD.

Diagnostic procedure

STEP	INSPECTION		ACTION
1	• Turn the AudioPilot^®2 function on. • Inspect the AudioPilot^®2 function operation while driving the vehicle. • Does the AudioPilot^®2 system operation properly?	Yes	The system is normal. Explain the AudioPilot^®2 function to the customer.
1		No	Go to the next step.
2	• Inspect the connection of the audio amplifier connector (AudioPilot^®2 microphone signal). • Inspect both the audio amplifier wiring harness-side connector terminal 1H, 1G and 1I for a poor connection (such as damaged/pulled-out pins, corrosion). • Are all the pins normal?	Yes	Repair or replace the pins and/or the connector.
2		No	Go to the next step.
3	• Inspect the connection of the AudioPilot^®2 microphone connector (2-pin). • Inspect the AudioPilot^®2 microphone wiring harness-side connector terminal A and B (2-pin) for poor connection (such as damaged/pulled-out pins, corrosion). • Are all pins normal?	Yes	Repair or replace the pins and/or the connector.
3		No	Go to the next step.
4	• Inspect continuity between the following terminals of the audio amplifier connector and body ground. ― Terminal 1H (AudioPilot^®2 microphone+) ― Terminal 1G (AudioPilot^®2 microphone-) ― Terminal 1I (vehicle speed signal) • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground.
4		No	Go to the next step.
5	• Inspect continuity between the following terminals of the audio amplifier connector and AudioPilot^®2 microphone/instrument cluster connector. ― Terminal 1H—AudioPilot^®2 microphone terminal B (+) ― Terminal 1G—AudioPilot^®2 microphone terminal A (-) ― Terminal 1I—Instrument cluster terminal O (vehicle speed signal) • Is there continuity?	Yes	Go to the next step.
5		No	Repair or replace for open circuit.
6	• Retrieve the DTCs from all vehicle modules using the M-MDS. • Is there the following DTC displayed? ― Vehicle speed signal ― CAN communication	Yes	Go to the appropriate DTC inspection.
6		No	Replace the audio amplifier. (See AUDIO AMPLIFIER REMOVAL/INSTALLATION.)
