TROUBLESHOOTING HINTS

• The steering wheel voice control switch may be 

defective.

• The combination meter may be defective.

• The clock spring may be defective.

• The wiring harness or connectors may have 

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

• MB992006: Extra Fine Probe

STEP 1. Check the combination meter. 
Check whether the illumination of combination meter works 
normally.
Q: Does the combination meter operate normally?

YES : Go to Step 2.
NO :  Diagnose the combination meter. (Refer to 

P.54A-69

.)

STEP 2. Check steering wheel voice control switch 
connector C-206 for loose, corroded or damaged 
terminals, or terminals pushed back in the connector.
Q: Is steering wheel voice control switch connector C-206 

in good condition?
YES : Go to Step 3.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

.

STEP 3. Check the wiring harness between steering wheel 
voice control switch connector C-206 (terminal 1) and 
ground.

• Check the ground wire for open circuit .
