How to display DTCs on the gauge control module (tach)
How to clear the DTC
22-75
No DTCs detectedAll DTCs have been displayed
DTC detected
(the letter and four digit number on the left
represents the DTC, the right two digit is the
unit code.)
While in Test Mode 1, the DTCs which have been detected and stored individually by various B-CAN (Body-controller
Area Network) units, will be shown one by one on the odometer display when the communication between the MICU
and the gauge control module is normal. To scroll through the DTCs, press the select/reset button.
The unit that has stored the code can be identified by the number shown on the multi-information display.
MICU 10
Gauge control module 50
Climate control unit 51
HandsFreeLink control unit 94
Immobilizer-keyless control unit 96
While in Test Mode 1, press and hold down the SELECT/RESET button for more than 10 seconds.

Troubleshooting - B-CAN System Diagnosis Test Mode 1 and Test Mode 2
(without the HDS)
A
(07WAZ-001010A)B
MPCS (MCIC) service connector 07WAZ-001010A
Check the ECM/PCM for DTCs and troubleshoot ECM/
PCM (see page 11-3) or F-CAN loss of communication
errors first, then do this diagnosis if the HDS is not
available.
1. Check the No. 23 (10 A) fuse in the under-hood fuse/relay box and No. 10 (7.5 A) fuse in the under-
dash fuse/relay box.
Go to step 2.
Find and repair the cause of the blown fuse.
2. Remove the left kick panel (see page 20-66).
3. Turn the ignition switch to ON (II), and move the ceiling light switch to the middle ( door) position.
4. Connect the MPCS service connector (A) to the MCIC socket (B) in the under-dash fuse/relay box.
5. Wait 5 seconds, and watch the ce iling light. When
the ceiling light flashes quickly once, and then goes
off the system is in Test Mode 1. 6. Check for B-CAN DTCs indicated by the gauge
control module (tach) odometer/trip meter display
while still in Test Mode 1. Push the SEL/RESET
switch button to display the next code. After you
get to the last code, the display shows END. If no
DTCs are stored, the display will read NO.
Go to step 7.
Go to step 10.
7. Record all DTCs and sort them.
8. Troubleshoot the DTCs in this order:  Battery voltage DTCs
 Internal error DTCs
 Loss of communication DTCs (begin with thelowest number first; for example, if B1008 and
B1011 are retrieved, troubleshoot B 1008 first)
 Signal error DTCs
9. Clear the DTCs by pressing and holding the SEL/ RESET switch button for about 10 seconds. You will
hear a beep to confirm the codes have been cleared.
Operate the devices that failed, and recheck for
codes.
10. Remove the MPCS service connector from the under-dash fuse/relay box socket for
5 10 seconds, then re-insert it to enter Mode 2.
When the system enters Mode 2, the ceiling light
will flash two times quickly and then go off.
NOTE: If the MPCS service connector is
disconnected for too short or too long of a time, or
the ignition switch is turned to LOCK (0), the
system will return to Test Mode 1.
11. The following tables list the circuits that can be checked in Test Mode 2. Operate the switch that is
most closely related to the problem. If the circuit is
OK, the ceiling light will blink once. If the circuit is
faulty, there will be no indication.
(cont’d)
Ar e t he f uses OK ? Are any DTCs indicated?

The Communication Line Check
Ending the self-diagnostic function
TYPE S model Error Code ListError code Type of communication line(s) error
Except TYPE S model Error Code List Error code Type of communication line(s) error
Example Indication
22-243
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.
