terminals pushed back in the connector. Repair the wiring
harness as necessary.
STEP 4. Check ETACS-ECU connectors C-307 and C-309 for
loose, corroded or damaged terminals, or terminals pushed
back in the connector.
Q:Is ETACS-ECU connectors C-307 and C-309 in good
condition?
YES:
Go to Step 5.
NO:
Repair or replace the damaged component(s). Refer to
GROUP 00E, Harness Connector Inspection P.00E-2.
STEP 5. Check the battery power supply circuit to the
ETACS-ECU. Measure the voltage at ETACS-ECU
connectors C-307 and C-309.
(1)
Disconnect ETACS-ECU connectors C-307 and C-309
measure the voltage available at the wiring harness side of
the connector.
ZC6022230002
Connector C-307
(Harness side)
(2)
Measure the voltage between ETACS-ECU connector C-307
terminal 2 and ground.
⦆
The voltage should measure approximately 12 volts
(battery positive voltage).
ZC6022230003
Connector C-309
(Harness side)
(3)
Measure the voltage between ETACS-ECU connector C-309
terminal 1 and ground.
⦆
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 7.
NO:
Go to Step 6.
STEP 6. Check the wiring harness between ETACS-ECU
connector C-306 (terminal 1 or 2) and the fusible link (34) or
(36).
Q:Is the wiring harness between ETACS-ECU connector
C-306 (terminal 1 or 2) and the fusible link (34) or (36) in
good condition?
YES:
No action is necessary and testing is complete.
NO:
The wiring harness may be damaged or the connector
(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector. Repair the wiring
harness as necessary. The system should communicate with
the ETACS-ECU normally.

DIAGNOSIS
STEP 7. Retest the system
Check that the ETACS-ECU functions work normally.
Q:Is the check result satisfactory?
YES:
The procedure is complete. (If no malfunctions are
found in all steps, an intermittent malfunction is
suspected. Refer to GROUP 00, How to Use Troubleshooting/
Inspection Service Points - How to Cope with Intermittent
Malfunction P.00-15).
NO:
Replace the ETACS-ECU.

Connector: C-317
TECHNICAL DESCRIPTION (COMMENT)
If there is an error to the ignition switch (ACC) input
signal, or the ACC relay inside the ETACS-ECU does
not operate, the ignition switch (ACC) signal is no
longer output to the communication line.

DIAGNOSIS
NO:
Repair or replace the damaged component(s). Refer to
GROUP 00E, Harness Connector Inspection P.00E-2. Check
that the input signal of ignition switch (ACC) is normal.
STEP 2. Check the ignition switch (ACC) line of the power
supply circuit to the ETACS-ECU. Measure the voltage at
ETACS-ECU connector C-317.
(1)
Disconnect ETACS-ECU connector C-317 and measure the
voltage available at the junction block side of the connector.
(2)
Turn the ignition switch to the "ACC" position.

(3)
Measure the voltage between terminal 7 and ground.
⦆
The voltage should measure approximately 12 volts
(battery positive voltage).
Q:Is the measured voltage approximately 12 volts (battery
positive voltage)?
YES:
Replace the ETACS-ECU. Check that the input signal
of ignition switch (ACC) is normal.
NO:
Go to Step 3.
STEP 3. Check the wiring harness between ETACS-ECU
connector C-317 (terminal 7) and the ignition switch (ACC).
Q:Is the wiring harness between ETACS-ECU connector
C-317 (terminal 7) and ignition switch (ACC) in good
condition?
YES:
