Diagnosis Procedure

INFOID:0000000006164931

Regarding Wiring Diagram information, refer to 

MWI-65, "Wiring Diagram"

.

1.

CHECK WASHER FLUID LEVEL SWITCH SIGNAL CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect combination meter connector and washer fluid level

switch connector.

3. Check continuity between combination meter harness connector

M24 (A) terminal 37 and washer fluid level switch harness con-

nector E106 (B) terminal 1.

4. Check continuity between combination meter harness connector

M24 (A) terminal 37 and ground.

Is the inspection result normal? 

YES

>> GO TO 2

NO

>> Repair harness or connector.

2.

CHECK WASHER FLUID LEVEL SWITCH GROUND CIRCUIT

Check continuity between washer fluid level switch harness connec-

tor E106 terminal 2 and ground.

Is the inspection result normal? 

YES

>> Inspection End.

NO

>> Repair harness or connector.

Component Inspection

INFOID:0000000006164932

1.

CHECK WASHER FLUID LEVEL SWITCH

Check continuity between washer fluid level switch terminals 1 and

2.

Is the inspection result normal?

YES

>> Inspection End.

NO

>> Replace washer fluid level switch.

Malfunction

Reference 

page

CAN COMM CIRC 
[U1000]

Malfunction is detected in CAN communication.

CAUTION:

Even when there is no malfunction on CAN communication system, malfunction may be 
misinterpreted when battery has low voltage (when maintaining 7 - 8 V for about 2 sec-
onds) or 10A fuse [No. 3, located in the fuse block (J/B)] is disconnected.

MWI-31

VEHICLE SPEED 
CIRC
[B2205]

Malfunction is detected when an erroneous speed signal is input.

CAUTION:

Even when there is no malfunction on speed signal system, malfunction may be misin-
terpreted when battery has low voltage (when maintaining 7 - 8 V for about 2 seconds).
