STEP 8. Check the battery power supply circuit to the CAN
box unit. Measure the voltage at CAN box unit connectors
C-15.
(1) Disconnect CAN box unit connectors C-15 measure the
voltage available at the wiring harness side of the
connector.
(2) Measure the voltage between CAN box unit connector C-15
terminal 10 and ground.
OK:Battery voltage.
Q: Is the measured voltage battery voltage?
YES : No action is necessary and testing is complete.
NO : Go to Step 9.
STEP 9. Check the wiring harness between CAN box unit
connectors C-15 (terminal 10) and ETACS-ECU connector
C-315 (terminal 9).
• Check the power supply line for open circuit and short cir-
cuit.
NOTE: Also check intermediate connector C-108 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector C-108 is damaged, repair
or replace the connector as described in GROUP 00E, Harness
Connector Inspection
.
Q: Is the wiring harness between CAN box unit connectors
C-15 (terminal 10) and ETACS-ECU connector C-315
