4 (E) - Body ground	Always	Below 1 Ω

(b) Measure the voltage according to the value(s) in the table below.

Standard Voltage:

Tester Connection	Condition	Specified Condition
8 (LR) - 4 (E)	Hazard warning switch off	Below 1 V
8 (LR) - 4 (E)	Hazard warning switch on	Alternating between 11 to 14 V and below 1 V (60 to 120 times per minute)
2 (LL) - 4 (E)	Hazard warning switch off	Below 1 V
2 (LL) - 4 (E)	Hazard warning switch on	Alternating between 11 to 14 V and below 1 V (60 to 120 times per minute)
1 (B) - 4 (E)	Always	11 to 14 V
3 (IG) - 4 (E)	Ignition switch ON	11 to 14 V
6 (EL) - 4 (E)	Ignition switch ON Headlight dimmer switch (turn left) off	9 V or higher
6 (EL) - 4 (E)	Ignition switch ON Headlight dimmer switch (turn left) on	Below 1 V
7 (ER) - 4 (E)	Ignition switch ON Headlight dimmer switch (turn right) off	9 V or higher
7 (ER) - 4 (E)	Ignition switch ON Headlight dimmer switch (turn right) on	Below 1 V
12 (HAZ) - 4 (E)	Hazard warning switch off	9 V or higher
12 (HAZ) - 4 (E)	Hazard warning switch on	Below 1 V

If the result is not as specified, there may be a malfunction in the turn signal flasher assembly.
