Step 5. Check the wiring harness between C-217
ETACS-ECU connector terminal No.3 and body
earth.

NOTE:

Prior to the wiring harness inspection, check junction
block connector C-205, and repair if necessary.

•

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

P.00-6

).

NO :

Repair the wiring harness.

Step 6. Retest the system.

Check that the battery power supply circuit to the
ETACS-ECU is normal.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

How to

Cope with Intermittent Malfunction

P.00-6

).

NO :

Replace the ETACS-ECU.
