HINT:

• The following troubleshooting flowchart is based on the premise that the engine is cranked normally. If the engine will not crank, proceed to PROBLEM SYMPTOMS TABLE .
• Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

1. READ DATA LIST (STARTER SIGNAL) 
   1. Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
   2. Turn the engine switch on (IG) and turn the tester ON.
   3. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST / PRIMARY / STARTER SIG.
   4. Confirm the starter signal status when the engine switch is operated.

      OK : GO TO NEXT STEP.

      Engine Switch Position	STARTER SIG
      On (IG)	OFF
      Start	ON

   OK : REPLACE ECM 

   NG : GO TO NEXT STEP. 

2. INSPECT PARK / NEUTRAL POSITION SWITCH 
   1. Move the shift lever to the P or N position.
   2. Disconnect the E25 PNP switch connector.
   3. Measure the resistance of the PNP switch.
