DTC P2532-772: Ignition Switch Run Position Circuit High [09/2013 - ]: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Enter the following menus: Powertrain / EV / Trouble Codes.
4. Read and record the DTCs and freeze frame data.
5. Clear the DTCs and freeze frame data.
6. Turn the power switch off.

NEXT: Go to next step 

1. Leave the vehicle for 15 seconds or more with the power switch on (IG) after clearing DTCs.

   HINT: 

   Leaving the vehicle for 15 seconds or more is required to detect DTC U0140-146.

2. Enter the following menus: Powertrain / EV / Trouble Codes.
3. Check if DTCs are output.
