Step 6. Measure the resistance at A-12X
front-ECU connector.
(1) Remove the front-ECU, and measure at the relay
box side.
(2) Resistance between A-12X front-ECU connector
terminal No.21 and body earth
OK: 2
Ω
or less
Q: Is the check result normal?
YES :
Go to Step 8.
NO :
Go to Step 7.
Step 7. Check the wiring harness between A-12X
front-ECU connector terminal No.21 and the body
earth.
•
Check the earth wires for open circuit.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
−
How to
Cope with Intermittent Malfunction
NO :
Repair the wiring harness.
Step 8. Connector check: C-219 ETACS-ECU
connector
Q: Is the check result normal?

Step 9. Check the wiring harness between C-219
ETACS-ECU connector terminal No.59 and A-12X
front-ECU connector terminal No.30.
NOTE:
Prior to the wiring harness inspection, check joint
connector C-02 and intermediate connector C-116,
and repair if necessary.
•
Check the communication lines for open circuit.
Q: Is the check result normal?
YES :
Go to Step 10.
NO :
Repair the wiring harness.

Step 10. Check whether the diagnosis code is
reset.
Replace the column switch, and then check that the
diagnosis code is not reset.
(1) Replace the column switch.
(2) Ignition switch: ON
(3) On completion, check that diagnosis code No.13
is not reset.
Q: Is diagnosis code No.13 set?
YES :
Replace the ETACS-ECU.
NO :
The procedure is complete.
Diagnosis code 21: Short circuit in SWS communication line
CAUTION
Whenever the ECU is replaced, ensure that the
communication circuit is normal.

DIAGNOSIS CODE SET CONDITIONS
If the SWS communication line voltage is kept at low
level for 0.3 second, the diagnosis code will be set. If
the ETACS-ECU data line voltage is kept at high
level for 0.3 second, or the ETACS-ECU has
received normal signal from the other ECUs or
switches, the ETACS-ECU will stop sending the
diagnosis code. While this code is set, the other
codes will not be set.
POSSIBLE CAUSES
•
Malfunction of the column switch
•
Malfunction of the front-ECU
•
Malfunction of the power window main switch
•
Malfunction of the ETACS-ECU
•
Damaged harness wires and connectors
