STEP 1. Check rear door switch (RH) connector D-08 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
STEP 2. Check the rear door switch (RH).
STEP 3. Measure at the lower metal part of the rear door switch (RH) in order to check the ground circuit to the rear door switch (RH).
note | Check that the rear door switch (RH) is grounded to the vehicle body by means of its mounting screw. |
Remove the cap, and measure the resistance value between the lower metal part and the ground.
- The resistance should equal 2 ohms or less.
Is the measured resistance 2 ohms or less?
Go to Step 4. Check the fit of the switch, and repair if necessary. Check that the input signal of rear door switch (RH) is normal.
STEP 4. Check ETACS-ECU connector C-412 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
STEP 5. Check the wiring harness between driver's door switch connector D-08 (terminal 3) and ETACS-ECU connector C-412 (terminal 8).
Check the input lines for open circuit and short circuit.Is the wiring harness between rear door switch connector D-08 (terminal 3) and ETACS-ECU connector C-412 (terminal 8) in good condition?
Replace the ETACS-ECU. Check that the input signal of rear door switch (RH) is normal. The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary. Check that the input signal of rear door switch (RH) is normal.
