DTC Troubleshooting (cont’d)

MICU Lost Communication with

the Door Multiplex Control Unit (DRLOCKSW
Message)

MICU Lost Communication with

the Combination Switch Control Unit (HLSW
Message)

NOTE: If you are troubleshooting multiple DTCs, be
sure to follow the instructions in B-CAN System
Diagnosis Test Mode A (see page 22-99).

1. Clear the DTCs with the HDS.

2. Turn the ignition switch OFF, and then back ON (II).

3. Wait for 6 seconds or more.

4. Check for DTCs with the HDS.

Go to step 5.

Intermittent failure, the door multiplex control

unit is OK at this time. Check for loose or poor
connection at the door multiplex connector (23P),
and at the under-dash fuse/relay box connector J
(21P). If the connections are good, check the battery
condition (see page 22-74) and the charging
system.

5. Check for DTCs with the HDS.

Go to Door Multiplex Control Unit Input Test

(see page 22-123).

Check for an open in the communication

circuit between the MICU and the door multiplex
control unit. If the circuit is OK, the MICU is faulty;
replace the under-dash fuse/relay box. If the circuit
is bad, repair the open.

NOTE: If you are troubleshooting multiple DTCs, be
sure to follow the instructions in B-CAN System
Diagnosis Test Mode A (see page 22-99).

1. Clear the DTCs with the HDS.

2. Turn the ignition switch OFF, and then back ON (II).

3. Wait for 6 seconds or more.

4. Check for DTCs with the HDS.

Go to step 5.

Intermittent failure, the MICU is OK at this

time. Check for loose or poor connection at the
combination switch control unit connector (12P),
and at the under-dash fuse/relay box connector
X (39P). If the connections are good, check the
battery condition (see page 22-74) and the charging
system.

5. Check for DTCs with the HDS.

Go to the Combination Switch Control Unit

Input Test (see page 22-124).

Check for an open in the communication

circuit between the MICU and the combination
switch control unit. If the circuit is OK, the MICU is
faulty; replace the under-dash fuse/relay box. If the
circuit is bad, repair the open.

NOTE: If you are troubleshooting multiple DTCs, be
sure to follow the instructions in B-CAN System
Diagnosis Test Mode A (see page 22-99).

1. Clear the DTCs with the HDS.

2. Turn the ignition switch OFF, and then back ON (II).

3. Wait for 6 seconds or more.

4. Check for DTCs with the HDS.

Go to step 5.

Intermittent failure, the gauge control module

is OK at this time. Check for loose or poor
connections at the gauge control module connector
B (14P), and at the under-dash fuse/relay box
connector N (45P). If the connections are good,
check the battery condition (see page 22-74) and
the charging system.

5. Check for DTCs with the HDS.

Go to the Gauge Control Module Input Test

(see page 22-122).

Check for an open in the communication

circuit between the MICU and the gauge control
module. If the circuit is OK, the MICU is faulty;
replace the under-dash fuse/relay box. If the circuit
is bad, repair the open.

NOTE: If you are troubleshooting multiple DTCs, be
sure to follow the instructions in B-CAN system
Diagnosis Test Mode A (see page 22-99).

1. Clear the DTCs with the HDS.

2. Turn the ignition switch OFF, and then back ON (II).

3. Check for DTCs with the HDS.

Go to step 4.

Intermittent failure, the door multiplex control

unit is OK at this time. Check for loose or poor
connections at the door multiplex control unit
connector (23P), and at under-dash fuse/relay box
connector J (21P). If the connections are good,
check the battery condition (see page 22-74) and
the charging system.

4. Check for DTCs with the HDS.

Go to the Door Multiplex Control Unit Input

Test (see page 22-123).

Check for an open in the communication

circuit between the MICU and the door multiplex
control unit. If the circuit is OK, the MICU is faulty;
replace the under-dash fuse/relay box. If the circuit
is bad, repair the open.

DTC Troubleshooting (cont’d)

MICU Lost Communication with

the Gauge Control Module (VSP/NE
Message)

Power Supply Circuit (IG1 Line)

Input Error for Relay Control Module and
MICU

NOTE: If you are troubleshooting multiple DTCs, be
sure to follow the instructions in B-CAN system
Diagnosis Test Mode A (see page 22-99).

1. Clear the DTCs with the HDS.

2. Turn the ignition switch OFF, and then back ON (II).

3. Check for DTCs with the HDS.

Go to step 4.

Intermittent failure, the gauge control module

is OK at this time. Check for loose or poor
connections at gauge control module connector B
(14P), and at under-dash fuse/relay box connector
N (45P). If the connections are good, check the
battery condition (see page 22-74) and the charging
system.

4. Check for DTCs with the HDS.

Go to the Gauge Control Module Input Test

(see page 22-122).

Check for an open in the communication

circuit between the MICU and the gauge control
module. If the circuit is OK, the MICU is faulty;
replace the under-dash fuse/relay box. If the circuit
is bad, repair the open, or short to power or
ground.

NOTE: If you are troubleshooting multiple DTCs, be
sure to follow the instructions in B-CAN System
Diagnosis Test Mode A (see page 22-99).

3. Check for DTCs with the HDS.

Go to step 4.

Intermittent failure, check for loose or poor

connections at relay control module connector J
(10P) and at under-dash fuse/relay box connector D
(17P). If the connections are OK, check the battery
condition (see page 22-74) and the charging
