SITUATION
Customer states there is no audio playback (telephony, navigation, radio) and system sounds (PDC, turn indicators,
acoustic signals) may also have failed.

CAUSE
Various issues that may cause the Receiver Audio Module (RAM) to stop operating.

CORRECTION
To avoid replacing the RAM unnecessarily, the RAM and accompanying systems must be diagnosed before
replacement.

PROCEDURE
For the Situation identified above, proceed as follows.
1. If all audio sources in the entertainment system are without audio playback (including telephony,
navigation announcements, radio) including failure of output system sounds such as Park Distance Control
(PDC), turn indicator, acoustic signal then:
a. Perform a measurement of the power supply:
A correct voltage supply and ground connection to the RAM must be ensured. Make sure to check
ALL power supplies and ground points.
b. Perform a measurement of the Ethernet Wake-up signal:
Measurement of the ETH_WUP signal should be made directly at the RAM in the event of an error.
It must be possible to measure at least 12 volts at the moment of switch-on. This voltage should last
for approx. 0.5 seconds (500 milliseconds) before falling below 1 volt.
The RAM is switched on with this signal. If no voltage can be measured on the Ethernet Wake-up
signal at the RAM, check the BDC/BCP connection to the RAM and repair it if necessary.
c. If the tests above are OK:

Carry out a battery reset for more than 30 minutes and check if RAM operation has been restored. If
effective, program/encode the vehicle to the latest Integration Level before a possible replacement
of the RAM and re-evaluate the RAMs operation.
2. All audio sources in the entertainment system without audio playback. However, system sounds such as
the Park Distance Control (PDC), turn indicators and acoustic signal can still be heard.
a. Ethernet connection test:
Check the ethernet connection between the head unit and the RAM and, if necessary, repair the
Ethernet connection (OABR). This includes checking the plug connections, pins and wiring at both
the head unit and RAM.
b. If the previous check was OK:
Carry out a battery reset for more than 30 minutes and check if RAM operation has been restored. If
effective, program/encode the vehicle to the latest Integration Level before a possible replacement
of the RAM and re-evaluate the RAMs operation.
Note: If there is a permanent communication fault with the head unit at the same time, the source of fault must be
determined in the head unit first. The RAM failure is probably a consequential effect.
Specific Note for the I20: Special tool and A-pillar paint finish protection instructions are included in the
“Moving the hood to the service position” repair instruction.
