Safety Precautions and Troubleshooting Basics

Safety precautions and fundamental points regarding troubleshooting

Note:
- The ABS is a vehicle safety system; the appropriate knowledge is necessary to work on the system.
- In order to check complaints and to be able to carry out pin-pointed troubleshooting, the Diagnostic Trouble Code (DTC) memory must be checked before commencing work on the ABS system.
- Only separate connectors when the ignition is switched off.
- Observe the appropriate instructions regarding the handling of brake fluid.
- ABS malfunctions are indicated by the ABS warning light illuminating. Certain malfunctions will only be recognized at speeds above 20 km/h (approximately 13 mph) (carry out road test).
- If the ABS -K47- and the brake system -K118 warning lights do not illuminate, but the brake system is not functioning correctly then the malfunction must be sought in the conventional braking system.
