Inspection Procedure 1 "The ignition switch (ACC)
signal is not received
STEP 7. Check the battery power supply circuit to the CAN
box unit. Measure the voltage at CAN box unit connector
C-13.
(1) Disconnect CAN box unit connectors C-13 measure the
voltage available at the wiring harness side of the
connector.
(2) Measure the voltage between CAN box unit connector C-13
terminal 10 and ground.
OK: The voltage should measure approximately 12
volts (battery positive voltage).
Q: Is the measured voltage approximately 12 volts (battery
positive voltage)?
YES : Replace the CAN box unit.
NO : Go to Step 8.
STEP 8. Voltage measurement at C-309 ETACS-ECU
connector. Check the battery power supply circuit to the
ETACS-ECU. Measure the voltage at ETACS-ECU
connector C-309.
(1) Disconnect the connector, and measure at the wiring
harness-side connector.
(2) Measure the voltage between C-309 ETACS-ECU
connector terminal 2 and ground.
OK: The voltage should measure approximately 12
volts (battery positive voltage).
Q: Is the measured voltage approximately 12 volts (battery
positive voltage)?
YES : Go to Step 9.
NO : Go to Step 11.
