STEP 1. Check whether AM or FM broadcast frequency is
received.
Check whether AM or FM broadcast frequency is received.
Q: Is AM or FM broadcast frequency received?
YES : Go to Step 2.
NO : Diagnose the radio <vehicles with radio and CD
player> or the multivision display <vehicles with
MMCS> (Refer to
<vehicles with radio and
CD player> or
<vehicles with MMCS>).
STEP 2. Using scan tool MB991958, diagnose the CAN bus
line.
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.
(1) Connect scan tool MB991958. Refer to "How to connect the
Scan Tool (M.U.T.-III)
."
(2) Turn the ignition switch to the "ON" position.
(3) Diagnose the CAN bus line.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?
YES <vehicles with radio and CD player> : Go to Step 3.
YES <vehicles with MMCS> : Go to Step 6.
NO <vehicles with radio and CD player or MMCS> :
Repair the CAN bus line. (Refer to GROUP 54C,
Diagnosis
).
STEP 3. Check satellite radio tuner connector C-18 and
radio and CD player connector C-109 for loose, corroded
or damaged terminals, or terminals pushed back in the
connector.
Q: Is satellite radio tuner connector C-18 or radio and CD
player connector C-109 in good condition?
YES : Go to Step 4.
NO : Repair or replace the damaged component(s). Refer

tuner connector C-18 (terminal 6, 14, 7) and multivision
display connector C-09 (terminal 75, 77, 76).
• Check the communication lines for open circuit and short
circuit.
NOTE: Also check intermediate connector C-110 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector C-110 is damaged, repair
or replace the connector as described in GROUP 00E, Harness
Connector Inspection
.
Q: Is the wiring harness between satellite radio tuner
