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, diagnose CAN
bus lines thoroughly by referring to
NO : If the resistance does not measure 120
± 20 , replace
the combination meter.

STEP 7. Check powertrain control module connector B-19
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
CAUTION
The strand end of the twisted wire should be within 10 cm
(4 inches) from the connector. For details refer to
Q: Is powertrain control module connector B-19 in good
condition?
YES : Go to Step 8.
NO : Repair the damaged parts.

STEP 8. Check the CAN bus lines (communication line
only) between intermediate connector C-29 and the
powertrain control module. Measure the resistance
between intermediate connector C-29 and powertrain
control module connector B-19.
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 intermediate connector C-29 and powertrain
control module connector B-19, and measure the resistance
between the wiring harness side connector of powertrain
control module connector B-19 and the male side connector
of intermediate connector C-29 (at front wiring harness
side).
(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 intermediate connector
terminal 11 and powertrain control module connector
terminal 17.
OK: 2 ohms or less
(5) Measure the resistance between joint connector (3)
terminal 12 and powertrain control module connector
terminal 18.
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 the resistance measures 2 ohms or less, go to Step
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 powertrain control module
connector.
