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
related to the B-CAN system.
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
• Key interlock
• 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).
Is the symptom r elated to the B-CAN system?
Ar e all contr ol units communicating with the HDS?

Go to step 5.
If the problem is related to one of the
following items, go to B-CAN System Diagnosis
Test Mode C (see page 22-95) if the system does
not stop or turn off. Go to Test Mode D (see page
22-96) if the system does not run or turn on.
• Exterior lights
• Turn signals
• Entry light control
• Interior lights
• Horn (security and panic)
• Wiper/washer
If the problem is related to one of the following
items, go to the troubleshooting for that individual
system.
• Gauge control module
• Door-open and trunk-open indicators
• Chimes (key-in, seat belt, lights-on, and parking
brake)
• Security
• Keyless entry
• Key interlock
• Dash light brightness control
• Audio system
• Navigation (if equipped)
• HandsFreeLink (if equipped)
5. Record all DTCs, and sort them by DTC type.
6. Troubleshoot the DTC(s) in this order:
• Battery voltage DTCs.
• Internal error DTCs.
• Loss of communication DTCs. Begin
troubleshooting with the lowest number first
(Example: if DTC B1008 and B1011 are retrieved,
begin by troubleshooting B1008).
• 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.
Replace the MICU.
3. Do the input test for the unit not communicating
with the HDS.
