See step 2

CHECK FOR DTC (ELECTRONICALLY CONTROLLED BRAKE SYSTEM)

Check if electronically controlled brake system DTCs are output.

for HEV Model
Chassis > Brake/EPB > Trouble Codes

Chassis > Brake Booster > Trouble Codes
for Gasoline Model
Chassis > Brake/EPB > Trouble Codes

Result

Result	Proceed to
DTCs are not output	A
DTCs are output	B

Result:

B

GO TO ELECTRONICALLY CONTROLLED BRAKE SYSTEM

for HEV Model: Refer to DIAGNOSTIC TROUBLE CODE CHART [11/2022 - 12/2024] , or refer to DIAGNOSTIC TROUBLE CODE CHART [12/2024 - ]

for Gasoline Model: Refer to DIAGNOSTIC TROUBLE CODE CHART [11/2022 - 11/2023] , or refer to DIAGNOSTIC TROUBLE CODE CHART [11/2023 - 12/2024] , or refer to DIAGNOSTIC TROUBLE CODE CHART [12/2024 - ]

Result:

A

See step 3

PERFORM ACTIVE TEST USING GTS

Perform the Active Test according to the display on the GTS.

Body Electrical > Combination Meter > Active Test

Tester Display	Measurement Item	Control Range	Diagnostic Note
Speed Signal Input (0)	Vehicle speed test signal input* (0 km/h, 0 mph)	ON	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.
Speed Signal Input (40)	Vehicle speed test signal input* (40 km/h, 40 mph)	ON	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. The value displayed on the speedometer may deviate.*
Speed Signal Input (80)	Vehicle speed test signal input* (80 km/h, 80 mph)	ON	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. The value displayed on the speedometer may deviate.*
Speed Signal Input (120)	Vehicle speed test signal input* (120 km/h, 120 mph)	ON	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. The value displayed on the speedometer may deviate.*
Speed Signal Input (160)	Vehicle speed test signal input* (160 km/h, 160 mph)	ON	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. The value displayed on the speedometer may deviate.*
Speed Signal Input (200)	Vehicle speed test signal input* (200 km/h, 200 mph)	ON	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. The value displayed on the speedometer may deviate.*
Speed Signal Input (240)	Vehicle speed test signal input* (240 km/h, 240 mph)	ON	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.

*: For the tolerance of each Speed Signal Input Active Test, refer to On-vehicle Inspection.
Refer to ON-VEHICLE INSPECTION [11/2022 - ]
