No.1 DEVIATION BETWEEN DRIVING DIAGNOSTIC SCORE AND DRIVE FEEL [INTELLIGENT DRIVE MASTER (i-DM)]

id0903k6009700

Description

• Frequency of white gauge display is high even though vehicle is driven on level straightaway

• Driving diagnostic score according to stage is not displayed

• Driving diagnostic score is bad compared with another vehicle of same model

Possible cause

White gauge deviation due to pedal operation

• PCM detects malfunction and vehicle driving condition is in fail-safe

• Accelerator pedal position sensor signal error

― Accelerator pedal position sensor malfunction

― Accelerator pedal malfunction

― Wiring harness malfunction between accelerator pedal position sensor and PCM

• Vehicle speed signal malfunction

― ABS wheel speed sensor malfunction (improper installation, malfunction)

― ABS wheel-speed sensor rotor loss

• Engine malfunction (engine malfunction increases acceleration pedal depression)

― Abnormal acceleration

― Hesitation during acceleration

White gauge deviation due to steering operation

• Steering angle signal error

― Steering angle sensor malfunction

• Vehicle speed signal malfunction

― ABS wheel speed sensor malfunction (improper installation, malfunction)

― ABS wheel-speed sensor rotor loss

― Tire malfunction (pressure adjustment malfunction, irregular tire diameter)

VERIFY DTCs FOR RELATED MODULES

•  Using the M-MDS, verify DTCs for PCM, DSC HU/CM, BCM, information display/multi information display and instrument cluster.
(See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.0].)

(See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)

(See DTC INSPECTION [INSTRUMENT CLUSTER].)

(See DTC INSPECTION [INFORMATION DISPLAY/MULTI INFORMATION DISPLAY].)

(See DTC INSPECTION [BCM].)

•  Can DTCs be verified?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [SKYACTIV-G 2.0].)

(See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)

(See DTC TABLE [INSTRUMENT CLUSTER].)

(See DTC TABLE [INFORMATION DISPLAY/MULTI INFORMATION DISPLAY].)

(See DTC TABLE [BCM].)

No

•  System is normal.
If the vehicle is normal, refer to INTELLIGENT DRIVE MASTER (i-DM) for instruction, and explain the contents of the driving operation determination and display to the customer to have them understand that there is no problem in the system.

•  Symptom troubleshooting is completed.
