Description Of Reading Off Extended Diagnostic Trouble Code (DTC) Information
CONTENTS
Select type of description.
DESCRIPTION OF FROZEN VALUES
EXPLANATION
The values described below were stored in the control module memory when the diagnostic trouble code (DTC) was stored.
HINT: For information on abbreviations: see: (BRAKE SYSTEM, ABBREVIATIONS), below.
TIME SINCE THE DIAGNOSTIC TROUBLE CODE (DTC) WAS FIRST STORED
Time in hours when the diagnostic trouble code was stored for the first time. The brake control module (BCM) obtains the value from the central electronic module (CEM) via the CAN network. Time is the total time the central electronic module (CEM) has been in operation.
TOTAL MILEAGE
The value indicates the vehicle's total mileage in km.
OUTSIDE TEMPERATURE
The value indicates the outside temperature when the diagnostic trouble code (DTC) was stored. The brake control module obtains the value via the from the central electronic module via the CAN network.
POWER SUPPLY MODE
The value indicates the current status of the power supply mode.
- Key removed
- Key recently removed
- Key approved
- Ignition off after Accessory position
- Accessory position
- Accessory position after Ignition on
- Ignition on
- Running
- Start attempt
- Signal missing
MECU POWER SUPPLY
The value indicates the system voltage. The value is given in volts (V).
VEHICLE SPEED
The value indicates the vehicle speed in km/h.
CONTROL FUNCTION ABS
The value indicates if the ABS function was operating at the moment the diagnostic trouble code (DTC) was stored.
Value:
Active
Not active
CONTROL FUNCTION SC
The value indicates if the traction control function was operating at the moment the diagnostic trouble code (DTC) was stored.
Value:
Active
Not active
CONTROL FUNCTION TC
The value indicates if the traction control function (TRACS) was operating when the diagnostic trouble code was stored.
Value:
Active
Not active
CONTROL FUNCTION AYC
The value indicates if the stability function was operating at the moment the diagnostic trouble code (DTC) was stored.
Value:
Active
Not active
RSC CONTROL
The value indicates if the antiroll function (RSC) was operating when the diagnostic trouble code was stored.
Value:
Active
Not active
BRAKE SYSTEM, ABBREVIATIONS
ABBREVIATIONS
All functions below are not available in all vehicles or vehicle models. The brake system can consist of only ABS or ABS including TRACS, STC, or DSTC.
| Function | Description |
| ABS (Anti-lock Braking System) | Anti-lock braking. Prevents wheels from locking when braking. |
| AYC (Active Yaw Control) | Stability control. Prevents oversteering and understeering with active braking. |
| BA (Brake Assistance) | Brake assistance. Boosts braking force in case of sudden heavy braking. Brake assistance is electronic for vehicles with DSTC, mechanical for others. |
| EBD (Electronic Brake Distribution) | Electronic distribution of braking force. Distributes braking force between front and rear brakes. |
| SC (Stability Control) | Stability control. Reduces engine torque to obtain increased lateral stability when the wheels spin at speeds from 0 km/h to top speed. |
| TC (Traction Control) | Traction control. Brakes spinning wheel from 0 km/h - top speed. |
| RSC (Roll over Stability Control) | Monitors the car's inclination angle and acts on the brakes if the car is at risk of rolling over. |
| HDC (Hill Descent Control) | Helps the driver brake the car when driving "off-road" without the driver activating the brake pedal. |
| System | Description |
| ABS (Anti-lock Braking System) | Anti-lock braking. Includes the functions ABS and EBD. |
| DSTC (Dynamic STC) | Dynamic stability and traction control. Includes the functions ABS, EBD, SC, TC and AYC. |
| STC (Stability and Traction Control) | Traction and stability control. Includes the functions ABS, EBD, SC and TC. |
| TRACS (Traction Control System) | Traction control system for four-wheel drive cars. Includes the functions ABS, EBD and TC. |
| Other abbreviations | Description |
| BCM (Brake Control Module) | Name of control module for brake system (BCM). Includes functions such as ABS, AYC, EBA, EBD, SC, TC and RSC. |
| CAN (Controller Area Network) | Standardized protocol for serial communication between control modules. |
