ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT SPEEDOMETER

NOTICE:

The combination meter assembly receives the vehicle speed signal from the skid control ECU (brake actuator assembly) via CAN communication. Therefore, perform the following inspection referring to values on the Data List of the skid control ECU (brake actuator assembly) because it is the source of the vehicle speed signal.
Data List values of the skid control ECU (brake actuator assembly) are used for this inspection. Therefore, make sure to perform this inspection after confirming that DTCs are not output.
If the tire size or tire inflation pressure is not within the specified range, or the tires are excessively worn, the speedometer indication error will increase. Therefore, make sure to perform this inspection after checking that the tire size, tire inflation pressure and tire wear are in the specified range.

(a) Warm up the engine.

(b) Read the Data List according to the display on the GTS.

180	184.6 to 187.6
200	205.1 to 208.1
220	225.6 to 228.6

Reference mph:

GTS Indication (mph)	Acceptable Range (mph)
20	20.5 to 23.0
40	41.0 to 43.5
60	61.5 to 65.0
80	82.0 to 86.0
100	102.6 to 107.1
120	123.1 to 128.0
140	143.6 to 148.9

OK:

Speedometer reading is within the acceptable range at each vehicle speed.

2. INSPECT TACHOMETER

(a) Warm up the engine.

(b) Read the Data List according to the display on the GTS.

5000	4800 to 5200
6000	(5750 to 6250)

OK:

Tachometer reading is within the acceptable range at each engine speed.

3. INSPECT WARNING AND INDICATOR LIGHT ILLUMINATION (INITIAL CHECK)

(a) Turn the ignition switch off.

(b) Turn the ignition switch to ON, and check the operation of the warning and indicator lights in the following table.

OK:

All of the lights illuminate and then turn off

Warning or Indicator Light
Brake warning light / red (malfunction)
Brake warning light / yellow (minor malfunction)
SRS warning light
EPS warning light
MIL (Check engine warning light)
PCS warning light
Automatic high beam indicator light
Slip indicator light
VSC OFF indicator light
ABS warning light
Eco driving indicator light
Stop and start indicator light

HINT:

The illumination of each warning light and indicator light varies.
