NOTE: Also check intermediate connectors D-111 and G-11 for
loose, corroded, or damaged terminals, or terminals pushed
back in the connector. If intermediate connectors D-111 or G-11
is damaged, Repair or replace the damaged component(s) as
described in GROUP 00E, Harness Connector Inspection
.
Q: Is the wiring harness between back door lock actuator
switch connector I-05 (terminal 4) and ETACS-ECU
connector D-223 (terminal 47) in good condition?
YES : Replace the ETACS-ECU. If the functions, which are
described in "CIRCUIT OPERATION", work normally,
the input signal from the back door lock actuator
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 back door lock actuator switch should be normal.
STEP 20. Check the wiring harness between driver's door
lock actuator switch connector H-10 (terminal 1) and
ground.
