NOTE: Also check joint connector D-01, junction block connec-
tors D-208, D-212 and intermediate connector E-11 for loose, 
corroded, or damaged terminals, or terminals pushed back in 
the connector. If joint connector D-01, junction block connector 
D-208, D-212 or intermediate connector E-11 is damaged, 
Repair or replace the damaged component(s) as described in 
GROUP 00E, Harness Connector Inspection 

P.00E-2

. 

Q: Is the wiring harness between transmission range 

switch connector C-04 (terminal 7) and the ignition 
switch (IG1) in good condition?
YES : No action is necessary and testing is complete.
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 rear 
wiper operates normally, it indicates that a correct "R" 
position signal is sent from the transmission range 
switch.

STEP 5. Check ETACS-ECU connector D-224 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Are ETACS-ECU connector D-224 in good condition?

YES : Go to Step 6.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection

. If the rear wiper operates normally, it 

indicates that a correct "R" position signal is sent from 
the transmission range switch.

STEP 6. Check the wiring harness between transmission 
range switch connector C-04 (terminal 8) and ETACS-ECU 
connector D-224 (terminal 35).
