CHECK WAVEFORM DATA ON THE SUBARU SELECT MONITOR (WHILE DRIVING).

1) Drive at a constant speed between 80 — 112 km/h (50 — 70 MPH).

2) After 5 minutes have elapsed in the condition of step 1), use the Subaru Select Monitor while still driving to read the waveform data.

• At normal condition

• At abnormal condition (numerous inversion)

QUESTION

Is a normal waveform displayed?

Yes No

Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the fault condition, and reperform the check.

NOTE:

In this case, there may be a temporary connector contact failure.
