(1)Disconnect the joint connector
(CAN2) and the A/C-ECU connector, and measure
at the wiring harness side. (2)Ignition switch: OFF
(LOCK) (3)
caution |
When measuring the resistance,
disconnect the negative battery
terminal. For details refer to .
|
Ensure that the negative battery terminal is
disconnected.

(5)Continuity between C-09 joint
connector (CAN2) terminal No.19 and C-106 A/C-ECU
connector terminal No.9 OK: 2 ohms or
less
caution |
Strictly observe the specified
wiring harness repair procedure.

Q.
Are the check result normal?
<All the
resistances measure 2 Ω or less> Power supply
to the A/C-ECU may be suspected. Diagnose the air
conditioner system. Refer to
<except vehicles
for Hong Kong and Singapore> or
<vehicles for Hong Kong
and Singapore>.
<Either or all
of the voltages measure more than 2 Ω> Repair
the wiring harness between the joint connector (CAN2) and
the A/C-ECU connector.
