2). Check procedure:
Electrical resistance measurement:
a). Use the Ohm function of electric meter to check the resistance value of AISV
(As shown in figure 25 )
Figure 25 Measuring the resistance value of AISV
4). Malfunction determination:
Electrical resistance value = 26Ω± 2.6Ω(environmental temperature 20℃)
5). Abnormal phenomenon and treatment:
a). Sensor error or the coupler has bad contact.
b). Check wire harness for twisted or bad contact wires.
c). AISV abnormal, replace with a new component.
