Code No.U0215 P/W SW (DR) LIN timeout


caution Before replacing the ECU, ensure that the communication circuit is normal.

JUDGMENT CRITERIA



PROBABLE CAUSES



  • Faulty power window main switch
  • Malfunction of the LIN bus

DIAGNOSIS PROCEDURE


STEP 1. Connector check: C-411 and C-415 ETACS-ECU connector, F-13 power window main switch connector


Q. Is the check result normal?





STEP 2. Resistance measurement at the F-13 power window main switch connector


(1)Disconnect the connector, and measure at the wiring harness side.
(2)Measure the resistance between the F-13 power window main switch connector terminal No. 10 <LHD> or terminal No. 9 <RHD> and the body earth.
OK: Continuity exists (2 Ω or less)

Q. Is the check result normal?





STEP 3. Wiring harness check from F-13 power window main switch connector terminal No. 10 <LHD> or terminal No. 9 <RHD> to body earth



note Prior to the wiring harness inspection, check intermediate connector C-224 <LHD> or C-211 <RHD>, and repair if necessary.

Q. Is the check result normal?





STEP 4. Voltage measurement at the F-13 power window main switch connector.


(1)Disconnect the connector, and measure at the wiring harness side.
(2)Ignition switch: ON position
(3)Measure the voltage between the F-13 power window main switch connector terminal No. 5 <LHD> or terminal No. 4 <RHD> and the body earth.
OK: System voltage

Q. Is the check result normal?





STEP 5. Wiring harness check between the F-13 power window main switch connector terminal No. 5 <LHD> or terminal No. 4 <RHD> and the C-415 ETACS-ECU connector terminal No. 10



note Prior to the wiring harness inspection, check intermediate connector C-224 <LHD> or C-211 <RHD>, and repair if necessary.

Q. Is the check result normal?





STEP 6. Check the wiring harness wires between C-411 ETACS-ECU connector terminal No. 1 and F-13 power window main switch connector terminal No. 7.


note Prior to the wiring harness inspection, check intermediate connector C-225 <LHD> or C-212 <RHD>, and joint connector C-102, and repair if necessary.

Q. Is the check result normal?





STEP 7. Check whether the diagnosis code is reset.



(1)Erase the diagnosis code.
(2)Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
(3)Check if diagnosis code is set.

Q. Is the diagnosis code set?
