Inspection Procedure

HINT:

• This DTC chart is on the premise that the engine is cranked normally. If the engine is not cranked, proceed to the PROBLEM SYMPTOMS TABLE  (See .
• Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air/fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

1. READ VALUE OF TECHSTREAM (STARTER SIGNAL) 
   1. Connect the Techstream to the DLC3.
   2. Turn the ignition switch ON and turn the tester ON.
   3. Enter the following menus: Powertrain/Engine and ECT/Data List/All Data/Starter Signal.
   4. Confirm the starter signal status when the ignition switch is operated.

      OK 

      IGNITION SWITCH POSITION
      
      

      Ignition Switch Position	STARTER SIG
      ON	OFF
      Start	ON

   OK: Go to step  5

   NG: Go to Next Step 

2. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY 
   1. Move the shift lever to the P or N position.
   2. Disconnect the P1 Park/Neutral Position (PNP) switch connector.
   3. Measure the resistance of the PNP switch

      Standard resistance 

      STANDARD RESISTANCE
      
      

      Shift Position	Tester Connection	Specified Condition
      P	2 - 6, 4 - 5	Below 1 Ω
      R	1 - 2	Below 1 Ω
      N	2 - 9, 4 - 5	Below 1 Ω
      D	2 - 7	Below 1 Ω
      2	2 - 3	Below 1 Ω
      L	2 - 8	Below 1 Ω

   4. Reconnect the park/neutral position switch connector.

   NG: REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY (GO TO STEP   5  AFTER THE REPLACEMENT) 

   OK: Go to Next Step 

3. INSPECT IGNITION SWITCH ASSEMBLY 
   1. Disconnect the 118 ignition switch connector.
   2. Measure the resistance between the connector terminals shown in the chart below.

      Standard resistance 

      STANDARD RESISTANCE
      
      

      Switch Position	Tester Connection	Specified Condition
      LOCK	All Terminals	10 kΩ or higher
      ACC	2 - 3	Below 1 Ω
      ON	2 - 3, 2 - 4, 6 - 7	Below 1 Ω
      START	1 - 2, 2 - 4, 6 - 7, 7 - 8	Below 1 Ω

   3. Reconnect the ignition switch connector.

   NG: REPLACE IGNITION SWITCH ASSEMBLY (GO TO STEP   5  AFTER REPLACEMENT) 

   OK: Go to Next Step 

4. READ VALUE OF TECHSTREAM (STARTER SIGNAL) 
   1. Connect the Techstream to the DLC3.
   2. Turn the ignition switch ON and turn the tester ON.
   3. On the Techstream, enter the following menus: Powertrain/Engine and ECT/Data List/All Data/Starter Signal.
   4. Read the values.

      OK 

      IGNITION SWITCH POSITION
      
      

      Ignition Switch Position	Starter Signal
      ON	OFF
      START	ON

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

   OK: Go to Next Step 

5. CHECK WHETHER DTC OUTPUT RECURS (DTC P0617) 
   1. Connect the Techstream to the DLC3.
   2. Turn the ignition switch ON and turn the tester ON.
   3. Clear the DTCs.
   4. Drive the vehicle more than 25 mph (40 km/h) for 20 seconds or more.
   5. Read the DTCs.
