Even if DTC is displayed, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.

NOTE:

In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.

3.CHECK HARNESS (OPEN CIRCUIT).

1) Disconnect the SRF CM connector.

2) Using a tester, measure the voltage between SRF CM connector and chassis ground.

Connector & terminal

(B42) No. 1 (+) — Chassis ground (−):

Is the voltage 8 — 16 V-
