Speed Signal Input (0)	Vehicle speed test signal input (0)*	ON	-
Speed Signal Input (40)	Vehicle speed test signal input (40)*	ON	The value displayed on the speedometer may deviate. Reference mph: 40 → 39.6 to 42.4 Reference km/h: 40 → 38.8 to 43.3
Speed Signal Input (80)	Vehicle speed test signal input (80)*	ON	The value displayed on the speedometer may deviate. Reference mph: 80 → 80.4 to 83.6 Reference km/h: 80 → 79.5 to 84.5
Speed Signal Input (120)	Vehicle speed test signal input (120)*	ON	The value displayed on the speedometer may deviate. Reference mph: 120 → 121.4 to 124.6 Reference km/h: 120 → 120.5 to 125.5
Speed Signal Input (160)	Vehicle speed test signal input (160)*	ON	The value displayed on the speedometer may deviate. Reference km/h: 160 → 161.5 to 166.5
Speed Signal Input (200)	Vehicle speed test signal input (200)*	ON	The value displayed on the speedometer may deviate. Reference km/h: 200 → 202.5 to 207.5
Speed Signal Input (240)	Vehicle speed test signal input (240)*	ON	The value displayed on the speedometer may deviate. Reference km/h: 240 → 243.6 to 248.6

HINT:

*: When this Active Test is performed, an actual vehicle speed signal is sent via CAN communication to the combination meter assembly to operate the speedometer. The seat belt warning buzzer, etc. may operate when performing this Active Test.
