1.
Problem verification (without engine running):

Problem verification (without engine running)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Try to shift the transmission into reverse.

Can you shift the transmission into the reverse?

     
YES
     
     
     
Go to step 3.
     
NO
     
     
     
The failure is duplicated. Go to step 2.
2.
Reverse lockout solenoid check:

Reverse lockout solenoid check
?1.
Do the reverse lockout solenoid test.

Is the reverse lockout solenoid OK?

     
YES
     
     
     
The reverse lockout solenoid is OK. Check the change lever assembly, or inspect the internal transmission.?
     
NO
     
     
     
3.
Problem verification (with engine running):

Problem verification (with engine running)
?1.
Start the engine, and try to shift the transmission into reverse.

Can you shift the transmission into reverse?

     
YES
     
     
     
Intermittent failure, the system is OK at this time.?
     
NO
     
     
     
The failure is duplicated. Go to step 4.
4.
Shorted wire check (RVSLCK line*1*2/RVS LCK*3 line):

Shorted wire check (RVSLCK line/RVS LCK line)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Jump the SCS line with the HDS, and wait more than 1 minute.


?3.
Disconnect the following connector.
PCM connector No. 2 (58P)*2
PCM connector E (80P)*1*3

?4.
Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode
PCM connector No. 2 (58P)*2: disconnected
PCM connector E (80P)*1*3: disconnected
Reverse lockout solenoid 2P connector: disconnected
Test point 1
Reverse lockout solenoid 2P connector (female terminals) No. 2:
Test point 2
Body ground


Is there continuity?

     
YES
     
     
     
Repair a short to ground in the RVSLCK wire*1*2/RVS LCK*3 wire between the reverse lockout solenoid and the PCM.?
     
NO
     
     
     
The RVSLCK wire*1*2/RVS LCK wire*3 is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM, then recheck. If the symptom/indication goes away and the PCM was substituted, replace the original PCM.?
