STEP 29. Resistance measurement at A-07 joint
connector (CAN1) and A-03 ABS-ECU connector.
NOTE: When checking A-07 joint connector (CAN1),
disassemble and check the engine compartment
relay box by referring to
.
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 (CAN1) and the
ABS-ECU 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 A-07 joint connector (CAN1)
terminal No.2 and A-03 ABS-ECU connector
terminal No.15
OK: 2
Ω or less
(5) Continuity between A-07 joint connector (CAN1)
