2. Pump it to 118 kPa (1.2 kgf/cm² 17.1 psi), then check for leakage.

1. Install the V-bank cover with the 2 nuts.

   Torque:

   7.5 N*m{76 kgf*cm, 66 in.*lbf}

NOTICE:

1. Turn all electrical systems OFF.
   

1. Operate the inspection when the cooling fan motor is turned OFF.
   

1. Warm up the engine.

2. When using the intelligent tester.
   

   1. Connect the intelligent tester to the DLC3.

   2. Select the following menu items: DIAGNOSIS / ENHANCED OBD ll / DATA LIST / IGN ADVANCE.

   3. Inspect the ignition timing during idling.

      Ignition timing:

      7 to 24°CA BTDC during idling (Transmission in neutral position)
      

   4. Check that the ignition timing advances immediately when the engine speed is increased.

3. When not using intelligent tester.
   

   1. Using SST, connect the terminals 13 (TC) and 4 (CG) of the DLC3.

   4. Pull out the wire harness as shown in the illustration.

   5. Connect the tester probe of a timing light to the wire of the ignition coil connector for No. 1 cylinder.

      NOTICE:

      1. Use a timing light that detects the first signal.
         
      1. After checking, be sure to wrap the wire harness with tape.
         

   7. Inspect the ignition timing during idling.

      Ignition timing:

      8 to 12°CA BTDC during idling (Transmission in neutral position)
      

   8. Remove the SST from the DLC3.

   9. Inspect the ignition timing during idling.

      Ignition timing:

      7 to 24°CA BTDC during idling (Transmission in neutral position)
      

   10. Disconnect the timing light from the engine.

   11. Install the air cleaner cap sub-assembly.
