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 

P.00E-2

.

Q: Are the harness wires between RV interconnected D-07 

(terminal 33) and fuel level sensor G-03 (terminal 1) in 
good condition?
YES : Go to Step 6.
NO :  Repair them. The RV meter should operate normally.

STEP 6. Recheck for malfunction.
Q: Is a malfunction eliminated?

YES : If no malfunctions are not found in all steps, an 

intermittent malfunction is suspected. Refer to 
GROUP 00, How to Use Troubleshooting/Inspection 
Service Points 

− How to Cope with Intermittent 

Malfunction 

P.00-6

.

NO :  Replace the RV meter.

CIRCUIT OPERATION
The RV meter calculates the ambient air temperature 
using the ambient air temperature sensor fitted on 
the vehicle side. 

.

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

.

TROUBLESHOOTING HINTS

• Malfunction of the ambient air temperature sen-

sor 

• Damaged harness wires and connectors

.

DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

• MB991958: Scan Tool (MUT-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

• MB991827: MUT-III USB Cable

• MB991911: MUT-III Main Harness B

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. 

(2) When the adjusting switch is continuously pressed for more 

than five seconds, the service function is activated at the 
same time with the reception signal sound (pip sound) and 
the service mode screen is displayed.

(3) Check the communication and connection 

P.54A-238

.

Q: Isn't there any abnormality on the M-BUS?

YES : Go to Step 2.
NO :  Go to Step 3.

STEP 2. Check the communication and connection of the 
service function (SWS).
Q: Isn't there any abnormality on SWS?

YES : the RV meter display should operate normally.
NO :  Refer to Group 54B, SWS Symptom Procedure
