Troubleshooting - B-CAN System Diagnosis Test Mode A
A
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 symptom is
relatedtotheB-CANsystem.
NOTE: If the HDS is not available, do the Test Mode 1 and Test Mode 2 (see page 22-97).
 Always cycle the ignition switch within 3 seconds when prompted in the DTC troubleshooting
procedures.
1. Compare the symptom with this list of B-CAN related systems:
 Gauge control module
 Exterior lights
 Turn signals
 Entry light control
 Interior lights
 Door-open and trunk-open indicators
 Horns (security and panic)
 Chimes (key-in, seat belt, lights-on, and parking brake)
 Power window/moonroof timer
 Wiper/washer
Security
 Keyless entry
 Power door locks
Keyinterlock
 Dash light brightness control
Go to step 2.
Go to the system troubleshooting for the
system with the symptom. 2. Connect the HDS to the data link connector (A),
then turn the ignition switch to ON (II).
3. From the BODY ELECTRICAL menu, select UNIT INFORMATION, and then select CONNECTED UNIT
listed to see if the following control units are
communicating with the HDS.
MICU
 Gauge control module
 Immobilizer-keyless control unit
 Climate control unit
 HandsFreeLink control unit
NOTE:  If one or more of the units are not communicating with the HDS, DETECT will be
displayed.
 If the unit is not communicating or the vehicle is not equipped, ‘‘Not Available’’ will be displayed.
Go to step 4.
If any of the control units are not
communicating, go to B-CAN System Diagnosis
Test Mode B (see page 22-94). If all units are not
communicating or only the MICU is communicating,
go to DTC B1000 troubleshooting (see page 22-102).

 Internal error DTCs.
 Loss of communication DTCs. Begintroubleshooting with the lowest number first
(Example: if DTC B1008 and B1011 are retrieved,
begin by troubleshooting B 1008).
 Signal error DTCs. Do this diagnosis if any of the control units are not
communicating (Not Available is displayed in the HDS)
as found by the B-CAN System Diagnosis Test Mode A
(see page 22-93).
1. Using the HDS, select the system that has the symptom from the BODY ELECTRICAL menu.
2. Select DTCs, and then check for loss of communication DTCs.
Go to step 3.

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.

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.

Release Locked odometer mileage to the
original gauge control module.
22-276 Gauges
Rewriting the ODO Data and Transferring the Maintenance Minder Data to a
New Gauge Control Module
NOTE:
 Obtain a new gauge control module before starting the rewriting process.
 Rewriting is not possible on a gauge control module that will not communicate with the HDS.
 Make sure that the HDS shows the correct VIN for the car you are working on.
 One you have started this procedure, you must complete it before removing the HDS from the DLC.
 Connect a battery jump box (not a Battery charger) to insure that correct battery voltage will be maintained.
1. Before replacing the gauge control module, connect the HDS.
2. Select GAUGES from the BODY ELECTRICAL menu display.
3. Select ‘‘Gauge Control M odule Replacement (ODO
rewrite)’’ from the ADJUSTMENT menu, and follow
the instructions on the display to retrieve the ODO
data and the Maintenance Minder information.
4. Replace the gauge control module.
5. Follow the instructions on the display to write the new ODO data and Maintenance Minder data to a
new gauge control module. If the data transfer fails,
refer to the instructions below to release the locked
ODO data. If after you attempt to transfer mileage the odometer
has dashes ( ), garbled, or incorrect value
displayed, do the following start over. The original
gauge control module is going to be unlocked and
restored to its original state.
1. Confirm that you have the latest HDS version of software.
2. Make sure that the HDS shows the correct VIN for the car you are working on.
3. With the ignition switch to LOCK (0), reconnect the original gauge assembly.
4. Completely re-boot the HDS.
5. Clear any stored DTCs.
6. Navigation to Body. Electric/Gauges/Adjustment/Instrument Panel
Replacement.
7. Select ‘‘3. Releasing Locked ODO Data’’.
8. Follow the prompts and the Odometer mileage will be restored.
9. Start over and make sure the screen prompts are followed.
