   Is DTC P16E6 indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the transmission range switch and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot .

2. Determine possible failure area (short in ATPST/ATP-ST wire, others)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Disconnect the following connector.

   Transmission range switch 10P connector

   -3. 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 (female terminals) No. 7:
   Test point 2	Body ground

   Is there continuity?

   YES 

   Go to step 4.

   NO 

   Go to step 3.

3. Transmission range switch check

   -1. Shift the transmission to other than P or N position/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 (male terminals) No. 7: (transmission range switch side)
   Test point 2	Transmission range switch 10P connector (male terminals) No. 1: (transmission range switch side)

   Is there continuity?

   YES 

   Replace the transmission range switch .

   NO 

   Check for poor connections or loose terminals at the transmission range switch and the PCM, and test the transmission range switch . If they are OK, check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .

4. Shorted wire check (ATPST/ATP-ST line)

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

   -2. Disconnect the following connector.

   PCM connector E (80P)

   -3. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Transmission range switch 10P connector: disconnected
   	PCM connector E (80P): disconnected
   Test point 1	PCM connector E (80P) No. 67
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short in the ATPST/ATP-ST wire between the PCM (E67) and the transmission range switch.

   NO 

   The ATPST/ATP-ST wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .
