Step 8.
No sound from any of the sources : Go to Step 2.
STEP 2. Check the ETACS-ECU coding data.
Use scan tool MB991958 to diagnose the CAN bus lines.
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
