Step 4. Check whether the diagnosis code is
reset.
When A-11X front-ECU connector is disconnected,
check that diagnosis code No.21 is not reset. How-
ever, diagnosis code No.13 will be set at this time.
Q: Is diagnosis code No.21 set?
YES :
Replace the front-ECU.
NO :
Go to Step 5.
Step 5. Check whether the diagnosis code is
reset.
When E-05 power window main switch connector is
disconnected, check that diagnosis code No.21 is
not reset.
Q: Is diagnosis code No.21 set?
YES :
Replace the power window main switch.
NO :
Go to Step 6.
Step 6. Check that the hazard warning lamps
illuminate.
When the ignition switch is turned to the LOCK
(OFF) position, check if the hazard warning lamps
illuminate.
Q: Is the check result normal?
YES :
Refer to diagnosis code No.12 "Trouble
related to the column switch or improper
connection to the ETACS-ECU
NO :
Refer to inspection procedure A-2 "Check
the battery power supply circuit to the
ETACS-ECU
Diagnosis code 31: Open circuit in the signal line between the SRS-ECU and the ETACS-ECU (impact
detection signal)
Diagnosis code 32: Short circuit in the signal line between the SRS-ECU and the ETACS-ECU (impact
detection signal)
CAUTION
Whenever the ECU is replaced, ensure that the
input signal circuit is normal.
