HINT:

MONITOR DESCRIPTION
These DTCs indicate a problem with the park/neutral position switch assembly, transmission control switch or wire harness of their circuits.
The park/neutral position switch assembly detects the shift lever position and sends a signal to the TCM. For safety, the park/neutral position switch assembly detects the shift lever position so that the engine can be started only when the shift lever is in P or N.
The park/neutral position switch assembly sends a signal to the TCM according to the shift lever position (P, R, N or D).
The TCM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously. The TCM will then illuminate the MIL and store a DTC.

- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the engine switch off and wait for 2 minutes or more.
- Turn the engine switch on (IG) and turn the Techstream on.
- Wait with the shift lever in each position (P, R, N or D) for 60 seconds or more each with the engine switch on (IG). [*1]
-
Wait for 2 seconds or more with the shift lever in M. [*2]
HINT:
[*1] and [*2]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / Transmission / Utility / All Readiness.
- Input the DTC: P070513 or P070562.
-
Check the DTC judgment result.
