NOTE: After inspecting intermediate connector F-07, D-111 
and joint connector D-29, inspect the wires. If intermediate con-
nector F-07, D-111 and joint connector D-29 are damaged, 
repair or replace them. Refer to GROUP 00E, Harness Con-
nector Inspection

good condition?
YES : Go to Step 6.
NO :  Repair them. The RV meter should operate normally.

STEP 6. Recheck for malfunction.

.

TECHNICAL DESCRIPTION (COMMENT)
When other indications are normal, the malfunction 
of outside air temperature sensor is considered. 

.

TROUBLESHOOTING HINTS

• Malfunction of the outside air temperature sensor 

• Damaged harness wires and connectors

.

DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

• MB991502: Scan Tool (MUT-II)

STEP 1. Check the communication and connection (M-
BUS) of the service function.
(1) Press the adjusting switch with the ignition switch at the 

"LOCK" (OFF) position. While holding the switch on the 
pressed condition, turn the ignition switch to "ACC" position.
