Wiring diagram
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” . |

1 |
Special tool 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 . |

Special tool Tester knob indication
voltage ( Pair control solenoid valve voltage battery voltage ((+) terminal: o/w – (–) terminal: ground) Is the voltage ok? |
|
Open or short circuit in the o/w wire. |
Active control inspection
Use of sds diagnosis reset procedures
Note
the malfunction code is memorized in the
ecm also when the lead wire coupler of any
sensor is disconnected. Therefore, when a
lead wire coupler has been disconnected at
the time of diagnosis, erase the stored
malfunction history code using sds.
After repairing ...
Show data when trouble (displaying data at
the time of DTC)
Use of sds
Ecm stores the engine and driving conditions (in the form of data as shown in
the figure) at the moment of the
detection of a malfunction in its memory. This data is called “show data when
trouble”.
Therefore, it is possible to know engine and driving conditions (e.G., Whether
...
Sds check
Using sds, sample the data at the time of new and periodic vehicle
inspections.
After saving the sampled data in the computer, file them by model and by user.
The periodically filed data help improve the accuracy of troubleshooting since
they can indicate the condition of vehicle
