14-22 VZR1800 ('08-MODEL)
"C49" (P1768) or "C61" (P1656) PAIR CONTROL SOLENOID
VALVE CIRCUIT MALFUNCTION
DETECTED CONDITION
PAIR control solenoid valve voltage is not input to
ECM.
ECM
PAIR. R
Step 2
1) Turn the ignition switch ON.
2) Measure the voltage between O/B wire and ground.
 PAIR valve voltage: Battery voltage
 09900-25008: Multi-circuit tester set
 Tester knob indication: Voltage ()
Is the voltage OK?
• 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.
YES
• 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.
3) After repairing the trouble, clear the DTC using SDS tool.
