YES: Replace the ETACS-ECU. If the functions, which are described in "CIRCUIT OPERATION", work normally, the input signal from the driver's
door switch should be normal.
NO: 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. If the functions, which are described in "CIRCUIT OPERATION", work normally, the input signal
from the driver's door switch should be normal.
STEP 7. Measure at the lower metal part of the passenger's door switch in order to check the ground circuit to the front passenger's door
switch.
NOTE: Check that the front passenger's door switch 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.
Q: Is the measured resistance 2 ohms or less?
YES: Go to Step 8.
NO: Check the fit of the switch, and repair if necessary. If the functions, which are described in "CIRCUIT OPERATION", work normally, the input
signal from the front passenger's door switch should be normal.
STEP 8. Check front passenger's door switch connector D-01 for loose, corroded or damaged terminals, or terminals pushed back in the
connector.
Q: Is front passenger's door switch connector D-01 in good condition?
YES: Go to Step 9.
NO: Repair or replace the damaged component(s). Refer to Harness Connector Inspection. If the functions, which are described in "CIRCUIT
