When the battery is connected as shown, the motor should
run and then stop at the specified park position.

Q:Does the rear wiper motor operate normally?

YES:

 Go to Step 3.

NO:

 Replace the rear wiper motor. The rear wiper should

now stop at the specified park position.

STEP 3. Check rear wiper motor connector F-04 and ETACS-
ECU connector C-311 for loose, corroded or damaged
terminals, or terminals pushed back in the connector.

Q:Is  rear  wiper  motor  connector  F-04  and  ETACS-ECU

connector C-311 in good condition?

YES:

 Go to Step 4.

NO:

 Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2.

STEP 4. Check the wiring harness between rear wiper motor
connector F-04 (terminals 2,4) and ETACS-ECU connector
C-311 (terminals 4, 8).

NOTE: 

Also check intermediate connector D-12 for loose,

corroded or damaged terminals, or terminals pushed back in
the connector.

Q:Is the wiring harness between rear wiper motor connector

F-04  (terminals  2,4)  and  ETACS-ECU  connector  C-311

(terminals 4, 8) in good condition?

YES:

 Go to Step 5.

NO:

 Repair or replace the damaged component(s). Refer to
