STEP 4. Check the CAN bus lines (communication line
including the combination meter) between joint connector
(3) and the combination meter. Measure the resistance at
joint connector (3) C-02.
CAUTION
A digital multimeter should be used. For details refer to
CAUTION
The test wiring harness should be used. For details refer to
(1) Disconnect joint connector (3) C-02, and measure the
resistance at the wiring harness side of joint connector (3)
C-02.
(2) Turn the ignition switch to the "LOCK" (OFF) position.
CAUTION
Disconnect the negative battery terminal. For details refer
to
.
(3) Disconnect the negative battery terminal.
(4) Measure the resistance between joint connector (3)
terminals 4 and 15.
OK: 120
± 20 Ω
Q: Does the resistance measure 120
± 20 Ω?
YES : If the resistance measures 120
± 20 Ω, go to Step 7.
NO : If the resistance does not measure 120
± 20 Ω, go to
Step 5 .

STEP 5. Check the CAN bus lines (communication line
only) between joint connector (3) and the combination
meter. Measure the resistance at joint connector (3) C-02
and combination meter connector C-101.
CAUTION
A digital multimeter should be used. For details refer to
CAUTION
The test wiring harness should be used. For details refer to
(1) Disconnect joint connector (3) C-02 and combination meter
connector C-101, and measure the resistance between
each wiring harness side connector.
(2) Turn the ignition switch to the "LOCK" (OFF) position.
CAUTION
Disconnect the negative battery terminal. For details refer
to
.
(3) Disconnect the negative battery terminal.

(4) Measure the resistance between joint connector (3)
terminal 15 and combination meter connector terminal 15.
OK: 2 ohms or less
(5) Measure the resistance between joint connector (3)
terminal 4 and combination meter connector terminal 14.
OK: 2 ohms or less
CAUTION
Strictly observe the specified wiring harness repair proce-
dure. For details refer to
Q: Do all the resistances measure 2 ohms or less?
YES : If all the resistances measure 2 ohms or less, go to
Step 6.
NO : If either of the resistances measures more than 2
ohms or all the resistances measure more than 2
ohms, repair the wiring harness between joint
connector (3) and the combination meter connector,
and then go to Step 2.

STEP 6. Check the terminator resistor inside the
combination meter. Measure the resistance at combination
meter connector C-101.
CAUTION
A digital multimeter should be used. For details refer to
(1) Disconnect combination meter C-101, and measure the
resistance at the component side of combination meter
connector C-101.
(2) Measure the resistance between combination meter
connector terminals 14 and 15.
OK: 120
± 20 Ω
Q: Does the resistance measure 120
± 20 Ω?
YES : If the resistance measures 120
± 20 Ω, go to Step 2.
NO : If the resistance does not measure 120
± 20 Ω,
replace the combination meter, and then go to Step 2.
