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.

times to each position (lock and lock, unlock
and unlock) to ensure the door lock knob
switch is in the appropriate position. Go to function and input test for the system
related to the failure.
Repair the open, short, or replace the faulty
switch.

Sleep and Wake-up Mode Test
1. Shift to the sleep mode:Turn the ignition switch to LOCK (0), and remove the key. If the MICU receives no signals from the inputs listed
below, it will go into sleep mode in less than 40 seconds.
Driver’s door lock switch (LOCK or UNLOCK)
Driver’s door key cylinder switch (LOCK or UNLOCK)
Front passenger’s door lock switch (LOCK or UNLOCK)
Trunk lid latch switch (Trunk lid closed)
Hazard warning switch (OFF)
2. Confirm the sleep mode: Measure the frequency on the B-CAN communication line (PNK wire); there should be 0 Hz when the system is in
the sleep mode. Check the parasitic draw at the battery while shifting into the sleep mode; the amperage should
change from about 200 mA to less than 35 mA.
3. Shift to the wake up mode: When the ignition switch is turned to ON (II), the MICU, gauge control module, immob ilizer-keyless control unit,
and ECM/PCM wake up at the same time without ‘‘talking’’ to each other through the communication lines. When
any switch in the multiplex integrated control system is turned on, it wakes up its related control unit which, in
turn, wakes up the other units. After confirming the sleep mode, look in the following table for the switch most
related to the problem. Operate that switch and see if its control unit wakes up.
NOTE: If any control unit is faulty and will not wake up, several circuits in the system will malfunction at the same
time. In the table below, the control unit is followed by a list of the switches and input signals that can wake it up.
