C49" Pair Control Solenoid Valve Circuit Malfunction - Suzuki DL650K5 Service Manual

"C49" PAIR CONTROL SOLENOID VALVE CIRCUIT MALFUNCTION

DETECTED CONDITION
PAIR control solenoid valve voltage is not input in
ECM.
INSPECTION
Step 1
1) Remove the fuel tank. ("5-7)
2) Turn the ignition switch OFF.
3) Check the PAIR control solenoid valve coupler for loose or
poor contacts.

sure the resistance between terminals.
% PAIR control solenoid valve resistance:
! 09900-25008: Multi circuit tester set
& Tester knob indication: Resistance (Ω)
Is the resistance OK?
YES Go to Step 2
• Loose or poor contacts on the ECM coupler.
NO • Replace the PAIR control solenoid valve with a
