WASHER LEVEL SWITCH SIGNAL CIRCUIT
Description
INFOID:0000000006164930
Transmits the washer level switch signal to the combination meter.
Diagnosis Procedure
INFOID:0000000006164931
Regarding Wiring Diagram information, refer to
.
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.

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.
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).
