Step 2
1) Turn the ignition switch ON.
2) Measure the voltage between O/B wire and ground.
PAIR valve voltage: Battery voltage
(+ O/B – - Ground)
09900-25008: Multi-circuit tester set
Tester knob indication: Voltage ()
Is the voltage OK?
3) After repairing the trouble, clear the DTC using SDS tool.

• R/Y wire open or shorted to ground, or poor d
connection failure.
• If wire and connection are OK, intermittent trou-
ble 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.
NO Open or short circuit in the O/W wire.
