STEP 17. Resistance measurement at C-37
jumper connector and C-09 joint connector
(CAN2).
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 the joint connector (CAN2) and the
jumper connector, and measure at the wiring
harness side.
(2) Ignition switch: OFF (LOCK)
CAUTION
When measuring the resistance, disconnect the
negative battery terminal. For details refer to
(3) Ensure that the negative battery terminal is
disconnected.
(4) Continuity between C-37 jumper connector
terminal No.2 and C-09 joint connector (CAN2)
terminal No.16
OK: 2
Ω or less
(5) Continuity between C-37 jumper connector

more than 2
Ω> Repair the wiring harness
between the centre display connector and
the jumper connector.
STEP 19. Connector check: C-119 SRS-ECU
connector
CAUTION
The strand end of the twist wire should be within
10 cm from the connector. For details refer to
Q: Is the check result normal?
YES :
Go to Step 20 .
NO :
Repair the defective connector.
STEP 20. MUT-III CAN bus diagnostics (C-119
SRS-ECU connector disconnected)
(1) Disconnect the SRS-ECU connector, and
diagnose by using the MUT-III.
(2) Check that the MUT-III indications correspond to
the illustration.
