Troubleshooting

Caution

when using the multi-circuit tester, do not strongly touch the terminal of the ecm coupler with a needle pointed tester probe to prevent terminal damage.

 

Note

after repairing the trouble, clear the dtc using sds tool. Refer to use of sds diagnosis reset procedures .

 

Step

Action

Yes

No

1

  1. Turn the ignition switch off.
  2.  Remove the air cleaner box. Refer to air cleaner box removal and installation in section 1d .
  3.  Check the pair control solenoid valve coupler (1) for loose or poor contacts.

    If ok, then measure the pair control solenoid valve resistance.


  1. Remove the pair control solenoid valve. Refer to pair control solenoid valve removal and installation in section 1b .
  2.  Measure the resistance between terminals.

Special tool
(a): 0990025008 (multi
circuit tester set)

Tester knob indication resistance (Ω)

Pair control solenoid valve resistance 20 24 Ω at 20 30 c (68 86 f) (terminal terminal)


Is the resistance ok?

Go to step 2. Replace the pair control solenoid valve with a new one. Refer to pair control solenoid valve removal and installation in section 1b .

2

  1. Turn the ignition switch on.
  2.  Measure the voltage between the o/w wire and ground.

Special tool
(a): 0990025008 (multi
circuit tester set)

Tester knob indication voltage ( )


Pair control solenoid valve voltage battery voltage ((+) terminal: o/w () terminal: ground)


Is the voltage ok?

  • W/g wire open or shorted to ground, or poor 55 connection failure.
  •  If wire and connection are ok, intermittent trouble or faulty ecm.
  •  Recheck each terminal and wire harness for open circuit and poor connection.
  •  Replace the ecm with a known good one, and inspect it again. Refer to ecm removal and installation in section 1c .
Open or short circuit in the o/w wire.

Active control inspection

  1. Set up the sds tool. (Refer to sds operation manual for further details.)
  2.  Turn the ignition switch on.
  3. Click pair sol operating control (1).
