INSPECTION PROCEDURE
1 INSPECT FUSE(GAUGE2, ECU±B)
(a) Check continuity in the GAUGE, DOME fuse.
NG REPLACE FUSE
OK
2 CHECK COMBINATION METER ASSY(POWER SOURCE AND GROUND CIRCUIT)
(a) Remove the combination meter assy.
(b) Check continuity.
(1) Check continuity between the terminal C11±5 of the
combination meter connector and the body ground.
Standard: Continuity.
(c) Check the voltage.
(1) Measure the voltage between the terminal C11±20
of the combination meter connector and the body
ground.
Standard voltage: 10 ± 14 V
(2) Turn the ignition switch to ON.
(3) Measure the voltage between the terminal C11±21,
22 of the combination meter connector and the
body ground.
Standard voltage: 10 ± 14 V

(a)Inspect the ECU±B 2 and DOOR fuses (See page 68±1).
NG REPLACE FUSE

2 PERFORM ACTIVE TEST USING HAND±HELD TESTER
(a) Select the ACTIVE TEST, use the hand±held tester to generate a control command and then check that the power door lock operates.
HINT:
During the ACTIVE TEST, the hand±held tester sends a signal to the body ECU to drive all th\
e power door
lock motors. If the power door lock operates, the power door lock motor itse\
lf and the wire harness between
the power door lock motor and body ECU are considered to be functioning nor\
mally. Standard (Multiplex network body ECU):

3 CHECK MASTER SWITCH OR KEY CYLINDER OPERATION
(a) When manual door lock/unlock operation via the master switch cannot be p\
erformed, proceed to A.
(b) When manual door lock/unlock operation interlocked with the driver side door\
lock key cylinder cannot be performed, proceed to B.

3. CHECK DIAGNOSIS
(a) Using the hand±held tester, check for DTCs.
NOTICE:
Hand±held tester only:
When the diagnosis system is switched from normal mode to check mode, all the DTCs and freeze
frame data recorded in normal mode are erased. So before switching modes, always check the DTCs
and freeze frame data, and make a note of them.
(1) Prepare the hand±held tester.
(2) Connect the hand±held tester to the DLC3 under the instrument panel lower pad.
(3) Turn the ignition switch ON and push the hand±held tester switch ON.
(4) Use the hand±held tester to check for DTCs and freeze frame data, and make a note of them
(For operating instructions, see the hand±held tester instruction book).
(5) Confirm the details of the DTCs.
(b) Either of the following procedures will erase the DTCs and freeze frame data.
(1) Operating the hand±held tester to erase the codes (See the hand±held tester instruction book
for operating instructions).
(2) Disconnecting the battery terminals or ECU±B fuse.
4. DATA LIST
HINT:
Using the DATA LIST displayed on the hand±held tester, you can read the value of the switch, sensor, actua-
tor, etc. without parts removal. Reading the DATA LIST as the first step of troubleshooting is one way to short-
en the labor time.
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Read the DATA LIST, according to the display on the tester.
