COMMENTS ON TROUBLE SYMPTOM




PROBABLE CAUSES



  • Malfunction of bulb
  • Malfunction of under cover rear
  • Damaged harness wires and connectors

DIAGNOSIS PROCEDURE


STEP 1. Bulb check



Q. Is the check result normal?





STEP 2. Connector check: D-102 (RH), D-118 (LH) electric folding second seat connector


Q. Is the check result normal?





STEP 3. Voltage measurement at the D-102 (RH) and D-118 (LH) electric folding second seat connector


(1)Disconnect the connector, and measure at the wiring harness side.
(2)Measure the voltage between the D-102 (RH), D-118 (LH) electric folding second seat connector terminal No. 1 and the body earth.
OK: System voltage

Q. Is the check result normal?





STEP 4. Wiring harness check between the D-102 (RH), D-118 (LH) electric folding second seat connector terminal No. 1 and the fusible link (33)


note Before the wiring harness check, check the relay box connector C-308 and C-36, and the intermediate connector C-39, and then repair them if necessary.

  • Check the input line for open circuit.

Q. Is the check result normal?





STEP 5. Resistance measurement at the D-102 (RH) and D-118 (LH) electric folding second seat connector


(1)Disconnect the connector, and measure at the wiring harness side.
(2)Measure the resistance between the D-102 (RH), D-118 (LH) electric folding second seat connector terminal No. 5 and the body earth.
OK: Continuity exists (2 Ω or less)

Q. Is the check result normal?





STEP 6. Wiring harness check between the D-102 (RH), D-118 (LH) electric folding second seat connector terminal No. 5 and the body earth


Q. Is the check result normal?





STEP 7. Retest the system
