On-Vehicle Inspection

HINT

To release each connector lock, push the claw downward ("Release" in the illustration) and move the lock lever ("Move" in the illustration)

1. Install the skid control ECU and skid control ECU bracket.

   HINT

   If a DTC for the hybrid control system is output, the Active Test cannot be performed Therefore, it is necessary to install the skid control ECU

2. Temporarily install the engine oil level dipstick guide with the bolt and insert the dipstick.
   NOTE: Engine oil will overflow if the spark test is performed with the engine oil level dipstick guide not installed.
3. Connect the frame wire
4. Restore the power supply by connecting the following cables and installing the service plug grip
   • Cable to negative battery terminal.

   • Motor cable.
   • Generator cable.
   CAUTION:

   • In order to safely crank the engine, follow the installation precautions for each part.
   • The hybrid system uses high voltage circuits. Make sure to perform the procedures properly, as making a mistake can lead to electric shock and/or electric leakage.
   NOTE:

   • When performing inspections on electrical systems, take care to prevent burnout due to a short circuit.
   • Make sure to securely install the wire harnesses, clamps, brackets, etc.

Intelligent tester - Select. DIAGNOSIS / OBD/MOBD / HV ECU / ACTIVE TEST / COMPRESS TEST / ON.

1. Visually check that sparks occur while the engine is being cranked.
   NOTE:

   • Be sure to ground the spark plug when checking.
   • If the ignition coil has been struck or dropped, replace it.
   • Do not crank the engine for more than 2 seconds.

Result 

1. If there is a cylinder where sparks do not occur, replace its ignition coil with the ignition coil of a cylinder where sparks occur normally
2. Crank the engine and visually check that sparks occur at the cylinder with the normally operating ignition coil.

1. For intake side, refer to the following procedures (see DTC P0340 CAMSHAFT POSITION SENSOR CIRCUIT MALFUNCTION; DTC P0342 CAMSHAFT POSITION SENSOR "A" CIRCUIT LOW INPUT (BANK 1 OR SINGLE SENSOR); DTC P0343 CAMSHAFT POSITION SENSOR "A" CIRCUIT HIGH INPUT (BANK 1 OR SINGLE SENSOR); DTC P0345 CAMSHAFT POSITION SENSOR "A" CIRCUIT (BANK 2); DTC P0347 CAMSHAFT POSITION SENSOR "A" CIRCUIT LOW INPUT (BANK 2); DTC P0348 CAMSHAFT POSITION SENSOR "A" CIRCUIT HIGH INPUT (BANK 2) )
2. For exhaust side, refer to the following procedures (see DTC P0365 CAMSHAFT POSITION SENSOR "B" CIRCUIT (BANK 1); DTC P0367 CAMSHAFT POSITION SENSOR "B" CIRCUIT LOW INPUT (BANK 1); DTC P0368 CAMSHAFT POSITION SENSOR "B" CIRCUIT HIGH INPUT (BANK 1); DTC P0390 CAMSHAFT POSITION SENSOR "B" CIRCUIT (BANK 2); DTC P0392 CAMSHAFT POSITION SENSOR "B" CIRCUIT LOW INPUT (BANK 2); DTC P0393 CAMSHAFT POSITION SENSOR "B" CIRCUIT HIGH INPUT (BANK 2) )

HINT:

Move the lock lever in the direction indicated by the arrow to lock the connector.

1. Using a megohmmeter, measure the insulation resistance

   Standard insulation resistance

   Tester Connection	Condition	Specified Condition
   Spark Plug (terminal part) - Body Ground	Always	10 MΩ or higher

   If a megohmmeter is not available, perform the following simple inspection instead.

1. Set the vehicle to inspection mode (see INSPECTION MODE PROCEDURE ).
2. Quickly accelerate the engine to 2500 rpm 5 times.
3. Remove the spark plug.
4. Visually check the spark plug

   If the electrode is dry, the spark plug is functioning properly If the electrode is damp, proceed to the next step.

HINT

Maximum electrode gap for a used spark plug. 1.3 mm (0.0511 in)

If the gap is greater than the maximum, replace the spark plug.

Electrode gap for a new spark plug: 1.0 to 1.1 mm (0.0394 to 0.0433 in)

If the electrode has traces of wet carbon, allow it to dry and then clean it with a spark plug cleaner.

Standard air pressure: 

588 kPa (6.0 kgf/cm ²  , 85 psi) 

Standard duration: 

20 seconds or less 

HINT

Only use the spark plug cleaner when the electrode is free of oil. If the electrode has traces of oil, use gasoline to clean off the oil before using the spark plug cleaner.
