1. Remove the right inner fender (see page 20-171).
2. Disconnect the 2P connector (A) from the washermotor (B).
3. Test the motor by connecting battery power to terminal No. 1 and ground terminal No. 2 of the
washer motor. The motor should run.
 If the motor does not run, or fails to run smoothly, replace it.
 If the motor runs smoothly, but little or no washer fluid is pumped, check for a disconnected
or blocked washer hose, or a clogged washer
motor outlet. 1. Remove the right inner fender (see page 20-171).
2. Disconnect the 2P connector (A) from the washer
fluid level switch (B).
3. Remove the washer fluid level switch from the washer reservoir.
NOTE: Fluid may flow out of the opening.
4. Check for continuity between terminals No. 1 and No. 2 in each float position.
 There should be continuity when the float is down.
 There should be no continuity when the float is up.
5. If the continuity is not as specified, replace the switch.

Before troubleshooting the gauge system, refer to multiplex integrated control system B-CAN System Diagnosis Test
Mode A (see page 22-93).
The gauge control module (tach) has a self-diagnostic function shown, and also has a customizable reset function.
 The beeper drive circuit check.
 The indicator drive circuit check.
 The switch input test.
 The LCD segments check.
 The gauges drive circuit check (Tachometer, Fuel gauge, Coolant temperature gauge).
 The communication line check (B-CAN, F-CAN, and UART lines).
NOTE: Indicators are also controlled via the communication line.
Using the HDS, select Body Electrical, Gauges, then Function Test and do the self-diagnostic function.
Before doing the self-diagnostic function, check the No. 10 (7.5 A) fuse in the under-dash fuse/relay box and the No. 23
(10 A) fuse in the under-hood fuse/relay box. 1. Push and hold the SEL/RESET switch button.
2. Turn the headlights ON.
3. Turn the ignition switch to ON (II).
4. Within 5 sec., turn the headlights OFF, then ON and OFF again.
5. Within 5 sec., release the SEL/RESET switch button, and then push and release the button three times repeatedly.
NOTE:  While in the self-diagnostic mode, the dash lights brightness controller operates normally.
 While in the self-diagnostic mode, the SEL/RESET switch button is used to start the Beeper Drive Circuit Test and the Gauge Drive Circuit Check.
 If the vehicle speed exceeds 2 km/h (1.2 mph) or the ignition switch is turned to LOCK (0), the self-diagnostic mode ends.
(cont’d)
Move to self-diagnostic mode.

Normal (all segments come on.): Faulty (Error 1):
Fault (Error 13): Fault (Error 123):
While in the self-diagnostic mode, the Communication Line Check starts after the LCD Segments Check.
If all segments come on, the communication line is OK. If faulty, the word ‘‘Error’’ will be indicated on the odometer
display followed by number(s).
Error 1 F-CAN communication
Error 2 B-CAN communication
Error 12 F-CAN and B-CAN communication
Error 1 F-CAN communication
Error 2 B-CAN communication
Error 3 UART communication
Error 12 F-CAN and B-CAN communication
Error 13 F-CAN and UART communication
Error 23 B-CAN and UART communication
Error 123 F-CAN, B-CAN and UART communication
 If the word ‘‘Error 1’’ is indicated, there is a malfunction in the communication line between the gauge control module (tach) and the fast-controller area network (F-CAN). Check for DTCs in the ECM/PCM and troubleshoot any
DTCs found. If no DTCs are found, go to indicated troubleshooting.
 If the word ‘‘Error 2’’ is indicated, there is a malfunction in the communication line between the gauge control module (tach) and the body-controller area network (B-CAN). Go to indicated troubleshooting (B 1155 to B1160).
 Except TYPE S model: If the word ‘‘Error 3’’ is indicated, there is a malfunction in the UART communication line between the gauge control module (tach) and the gauge control module (speedo). Go to the gauge control module
(tach) input test and check terminal No. 20. If the wire harness is OK, substitute a known-good gauge control module
(speedo) and recheck.
If any F-CAN or B-CAN communication line errors are found, go to DTC check using HDS.
Turn the ignition switch to LOCK (0).
NOTE: If the vehicle speed exceeds 2 km/h (1.2 mph), the self-diagnostic function ends.
