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).
