CAUTION

Strictly observe the specified wiring harness 
repair procedure. For details refer to 

P.54C-7

.

Q: Is the check result normal?

YES : 

<All the resistances measure 2 

Ω or less> 

Power supply to the RV meter may be 
suspected. Diagnose the RV meter. Refer to 
.

NO  : 

<Either or all of the resistances measure 
more than 2 

Ω> Repair the wiring harness 

between joint connector (CAN1) and the RV 
meter connector.

Diagnosis Item 7: Diagnose when the M.U.T.-III cannot receive the data sent by ABS-ECU <vehicles 
with ABS> or ASTC-ECU <vehicles with ASTC>

CAUTION

When servicing a CAN bus line, earth yourself by touching a metal object such as an unpainted water 
pipe. If you fail to do, a component connected to the CAN bus line may be broken.

FUNCTION
The diagnostic result demonstrates that "the M.U.T.-
III cannot receive the sent data from the ABS-ECU 
<vehicles with ABS> or ASTC-ECU <vehicles with 
ASTC>" when the M.U.T.-III checks the periodically 

sent data from each ECU.
