INSTRUMENT CLUSTER INSPECTION

Speedometer Inspection

Using a speedometer tester

CAUTION:

When only the front or the rear wheels are driven using a speedometer tester, the DSC HU/CM may determine that the vehicle speed signal is in error and the engine cannot be stopped by the normal operation. If the engine cannot be stopped, perform an emergency engine stop operation. (See SERVICE CAUTIONS.)

1. Adjust the tire pressure to the specification. (See WHEEL AND TIRE SPECIFICATION.)

2. Using a speedometer tester, verify that the values are as indicated in the table. km/h

Speedometer indication (km/h)	Speedometer tester indication (km/h)
20	17.57—22.43
40	37.67—42.33
60	57.57—62.43
80	77.47—82.53
100	97.12—102.88
120	116.66—123.34
140	136.37—143.63
160	156.37—163.63
180	176.37—183.63
200	196.20—203.80
220	215.40—224.60

mph

Speedometer indication (mph)	Speedometer tester indication (mph)
10	9.07—10.92
20	19.10—20.89
30	29.07—30.92
40	39.03—40.95
50	48.98—51.00
60	58.85—61.13
70	68.693—71.277
80	78.579—81.387
90	88.577—91.385
100	98.58—101.38
110	108.58—111.38
120	118.51—121.44
130	128.41—131.53
140	138.41—141.53

If not as indicated in the table, perform the DTC inspection for the PCM and DSC HU/CM, and inspect the related wiring harnesses. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0)].) (See DTC INSPECTION [DSC HU/CM].)

If the PCM, DSC HU/CM, and related wiring harnesses are normal, replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

Using the M-MDS

1. Connect the M-MDS to the DLC-2.

2. After vehicle identification, select the following from the M-MDS initialization screen.

a. Select “DataLogger”.

b. Select “Modules”.

c. Select “IC”.

3. Using the simulation function SPEEDOMTR, verify that the values are as indicated in the table.

M-MDS display	Speedometer display
Off	Speedometer needle moves to approx. 0 km/h {0 mph}.
60 km/h	Speedometer needle moves to approx. 57—63 km/h {36—39 mph}.
120 km/h	Speedometer needle moves to approx. 116—124 km/h {72.1—77.0 mph}.

If not as indicated in the table, replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

Tachometer Inspection

CAUTION:

If the engine speed exceeds the allowable range, the engine could be damaged. Therefore, when inspecting the tachometer, do not allow the engine speed to exceed the allowable range indicated on the tachometer.

1. Connect the M-MDS to the DLC-2.

2. After vehicle identification, select the following from the M-MDS initialization screen.

a. Select “DataLogger”.

b. Select “Modules”.

c. Select “IC”.

3. Using the simulation function TACHOMTR, verify that the values are as indicated in the table.

M-MDS display	Tachometer display
Off	Tachometer needle moves to 0 rpm.
3000 RPM	Tachometer needle moves to approx. 3,050 rpm.
6000 RPM	Tachometer needle moves to approx. 6,100 rpm.

If not as indicated in the table, replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

LCD Inspection

1. Connect the M-MDS to the DLC-2.

2. After vehicle identification, select the following from the M-MDS initialization screen.

a. Select “DataLogger”.

b. Select “Modules”.

c. Select “IC”.

3. Using the simulation function item LCD_SEG, verify that the LDC displays as shown in the following figure.

If the LCD display is not as shown in the figure, replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

Warning/Indicator Light Illumination Inspection

1. Connect the M-MDS to the DLC-2.

2. After vehicle identification, select the following from the M-MDS initialization screen.

a. Select “DataLogger”.

b. Select “Modules”.

c. Select “IC”.

3. Using the simulation function WL+IL, verify that the warning/indicator lights in the following table are illuminated.

If any of the warning/indicator lights are not displayed, replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
