Mitsubishi 380. Manual — part 702
DIAGNOSIS
CONTROLLER AREA NETWORK (CAN)
54C-218
STEP 33. Check the CAN_L line (communication line only)
between joint connector (3) and the combination meter
connector for short to ground. 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 combination meter
connector C-101, 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)
terminal 15 and body ground.
OK: 1 k
Ω or more
CAUTION
Strictly observe the specified wiring harness repair proce-
dure. For details refer to
Q: Does the resistance measure 1 k
Ω or more?
YES : If the resistance measures 1 k
Ω or more, diagnose
CAN bus lines thoroughly by referring to
NO : If the resistance measures less than 1 k
Ω, repair the
wiring harness between joint connector (3) and the
combination meter connector.

STEP 34. Check the CAN_L line (communication line
including the ETACS-ECU) between joint connector (3) and
the ETACS-ECU connector for short to ground. 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)
terminal 16 and body ground.
OK: 1 k
Ω or more
Q: Does the resistance measure 1 k
Ω or more?
YES : If the resistance measures 1 k
Ω or more, go to Step
37 .
NO : If the resistance measures less than 1 k
Ω, go to Step
35.
STEP 35. Check ETACS-ECU connector C-218 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 ETACS-ECU connector C-218 in good condition?
YES : Go to Step 36.
NO : Repair the damaged parts.
