Test point 2
Body ground


Is there about 5 V?

     
YES
     
     
     
The ATP-RVS wire is OK. Go to step 3.
     
NO
     
     
     
Repair an open in the ATP-RVS wire between the transmission range switch and the TCM.?
3.
Transmission range switch check:

Transmission range switch check
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode
 
Transmission range switch 10P connector: disconnected
Test point 1
Transmission range switch 10P connector No. 1
Test point 2
Transmission range switch 10P connector No. 10


Is there continuity when the shift lever is in R position/mode, and no continuity when the shift lever is shifted to any other position/mode?

     
YES
     
     
     
The transmission range switch is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good TCM, then recheck. If this DTC goes away and the TCM was substituted, replace the original TCM.?
     
NO
     
     
     
Check for proper transmission range switch installation, then recheck. If the transmission range switch installation is OK, replace the transmission range switch.?
