(4) Check the conductivity of front fog light switch: When the switch is at OFF, terminals 1 and 2, 4
should be not conducted, when the switch is at ON, terminals 1 and 2, 4 should be conducted.
(5) Check the conductivity of control switch of front headlight before AUTO is lightened: When the
switch is at AUTO, terminals 5 and 6, 7 should be conducted.
4. Check front fog light relay as shown in Fig. 4-86.
Fig. 4-86
The relay falls into a normally open one. Check the front fog light relay, the resistance between
terminals 1 and 2 should be around 60～90Ω, while terminals 3 and 4 should be not conducted;
apply the battery voltage between terminals 1 and 2 of the relay, terminals 3 and 4 should be
conducted.
5. Check emergency alarm switch (electrical air conditioning) as shown in Fig. 4-87.
Fig. 4-87
(1) Check the conductivity of emergency light switch: The emergency light switch (electrical air
conditioning controller) is installed onto the real vehicle, and then pressed, if the switch flashes, it
is normally, if not, change the switch.
(2) Check the luminated light for emergency light switch: Connect the battery positive to terminal
B5 of emergency switch, negative to terminal B15, and the luminated light should be lightened.
6. Check the rear roof light: When the switch is at OFF, terminals should be not conducted with
each other, when the switch is at DOOR, terminals 2 and 3 should be conducted, when the switch
is at ON, terminals 2 and 1 should be conducted, as shown in Fig. 4-88.
Fig. 4-88
7. Check the flash signal control
(1) The flash signal is controlled by BCM body controller, as required in the table, check the
