It's in the ETACS ECU. C-304 ETACS-ECU connector terminal No. 11 in C-304
Font Material property Parallel Art Schematic

Black Font Slope Automotive exterior Parallel



(1)Remove the ETACS-ECU.
(2)Use jumper wires to connect C-317 ETACS-ECU terminal No. 6 to the positive battery terminal and C-304 ETACS-ECU terminal No. 11 to the negative battery terminal.
(3)Check for continuity between the C-307 ETACS-ECU terminal No. 1 and C-314 ETACS-ECU terminal No. 1 while connecting and disconnecting the jumper wire at the negative battery terminal.

Continuity (2 ohms or less) <Negative battery terminal connected>
  • Should be open loop. <Negative battery terminal disconnected>
(4)Install the ETACS-ECU.

Q. Is the measured resistance normal?

Go to Step 3.
Replace the ETACS-ECU. Then confirm that the malfunction symptom is eliminated.
