Sym MaxSym 600i ABS Service Manual

4. Fuel Injection System
4-29
AISV
Functional Description:
● Control power, has two-pin socket, one for the power supply pin, one
for grounding pin.
● Secondary air injection solenoid valve at the Idle (3500 rpm below)
actuator.
● At Idling, ECU control solenoid valve by the grounding circuit to be
moving or closing.
Testing Procedures:
Resistance Confirmation:
● Use of the "meter" Ohm stalls (Ω), measurement of the secondary air
injection solenoid valve resistance value.
Detection judge:
Resistance value = 26 ± 2.6Ω (20℃)
Treatment of abnormal phenomena:
● Secondary air injection solenoid valve internal short circuit or open
circuit, or coupler bad contact.
● Check whether the abnormal wire harness lines.
● Secondary air injection solenoid valve anomaly, the proposed
