СИСТЕМА АВТОМАТИЧЕСКОЙ ТРАНСМИССИИ, Diagnostic DTC:P0705

DESCRIPTION

The park/neutral position switch detects the shift lever position and sends signals to the TCM.

MONITOR DESCRIPTION

This DTC indicates a problem with the park/neutral position switch assembly or the wire harness in the park/neutral position switch assembly circuit.

The park/neutral position switch assembly detects the shift lever position and sends signals 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, N, R 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 illuminate the MIL and store the DTC.

INSPECTION PROCEDURE

PROCEDURE

1. READ VALUE USING GTS (SHIFT SW STATUS)

   
   

   1. Connect the GTS to the DLC3.

   2. Turn the engine switch on (IG).

   3. Turn the GTS on.

   4. Enter the following menus: Powertrain / ECT / Data List / Shift SW Status (P Range), Shift SW Status (R Range), Shift SW Status (N Range), Shift SW Status (D Range).

   5. According to the display on the GTS, read the Data List.

      ECT

      Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
      Shift SW Status (P Range)	Park/neutral position switch status/ ON or OFF	ON: Shift lever is in P OFF: Shift lever is not in P	When shift lever position displayed on the GTS differs from actual position, adjustment of park/neutral position switch assembly or shift cable may be incorrect.
      Shift SW Status (R Range)	Park/neutral position switch status/ ON or OFF	ON: Shift lever is in R OFF: Shift lever is not in R	When shift lever position displayed on the GTS differs from actual position, adjustment of park/neutral position switch assembly or shift cable may be incorrect.
      Shift SW Status (N Range)	Park/neutral position switch status/ ON or OFF	ON: Shift lever is in N OFF: Shift lever is not in N	When shift lever position displayed on the GTS differs from actual position, adjustment of park/neutral position switch assembly or shift cable may be incorrect.
      Shift SW Status (D Range)	Park/neutral position switch status/ ON or OFF	ON: Shift lever is in D or M OFF: Shift lever is not in D or M	When shift lever position displayed on the GTS differs from actual position, adjustment of park/neutral position switch assembly or shift cable may be incorrect.

      Result

      Result	Proceed to
      Data List value is not within the normal condition	A
      Data List value is within the normal condition	B

2. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY

   
   
   1. 

      Text in Illustration

      *a	Component without harness connected (Park/Neutral Position Switch Assembly)

      Disconnect the park/neutral position switch assembly connector.

   2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition 6 (PL) - 2 (RB) Shift lever in P Below 1 Ω 1 (RL) - 2 (RB) Shift lever in R Below 1 Ω 9 (NL) - 2 (RB) Shift lever in N Below 1 Ω 7 (DL) - 2 (RB) Shift lever in D, M, "+" or "-" Below 1 Ω 6 (PL) - 2 (RB) Shift lever not in P 10 kΩ or higher 1 (RL) - 2 (RB) Shift lever not in R 10 kΩ or higher 9 (NL) - 2 (RB) Shift lever not in N 10 kΩ or higher 7 (DL) - 2 (RB) Shift lever not in D, M, "+" or "-" 10 kΩ or higher

3. CHECK PARK/NEUTRAL POSITION SWITCH ASSEMBLY (POWER SOURCE)

   
   
   1. 

      Text in Illustration

      *a	Front view of wire harness connector (to Park/Neutral Position Switch Assembly)

      Disconnect the park/neutral position switch assembly connector.

   2. Turn the engine switch on (IG).

   3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Switch Condition Specified Condition F48-2 (RB) - Body ground Engine switch on (IG) 11 to 14 V

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR (PARK/NEUTRAL POSITION SWITCH ASSEMBLY - BATTERY)

   OK

4. CHECK HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH ASSEMBLY - TCM)

   
   
   1. 

      Text in Illustration

      *a	Rear view of wire harness connector (to TCM)

      Disconnect the TCM connector.

   2. Turn the engine switch on (IG).

   3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage

      Tester Connection Condition Specified Condition A74-3 (P) - Body ground Engine switch on (IG) Shift lever in P 11 to 14 V A74-11 (R) - Body ground Engine switch on (IG) Shift lever in R 11 to 14 V* A74-10 (N) - Body ground Engine switch on (IG) Shift lever in N 11 to 14 V A74-20 (D) - Body ground Engine switch on (IG) Shift lever in D, M, "+" or "-" 11 to 14 V A74-3 (P) - Body ground Engine switch on (IG) Shift lever not in P Below 1 V A74-11 (R) - Body ground Engine switch on (IG) Shift lever not in R Below 1 V A74-10 (N) - Body ground Engine switch on (IG) Shift lever not in N Below 1 V A74-20 (D) - Body ground Engine switch on (IG) Shift lever not in D, M, "+" or "-" Below 1 V

      Tech Tips

      *: The voltage will drop slightly due to the turning on of the back-up light.
