HINT:

• The following troubleshooting flowchart is based on the premise that the engine is cranked normally. If the engine will not crank, proceed to the problem symptoms table (see ).
• 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 VALUE USING INTELLIGENT TESTER (STARTER SIGNAL) 
   1. Connect the intelligent tester to the DLC3.
   2. Turn the ignition switch ON and turn the tester ON.
   3. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST / ALL / STARTER SIG.
   4. Check the value displayed on the tester when the ignition switch is turned to the ON and START positions.

   Ignition Switch Position	STARTER SIG
   ON	OFF
   START	ON

   OK : REPLACE ECM 

   NG 

2. INSPECT PARK/NEUTRAL POSITION SWITCH OR CLUTCH START SWITCH 
   1. Inspect the Park/Neutral Position (PNP) switch (for A/T models).
      1. Disconnect the P1 PNP switch connector.
      2. Measure the resistance when the transmission gear selector lever is moved to each position.

      Standard resistance

   2. Inspect the clutch start switch (for M/T models).
      1. Disconnect the C5 clutch start switch connector.
      2. Measure the resistance when the clutch start switch is ON and OFF.
