Dif-OV (LD1), Shorted to GND Detection
â–¶ How to fix
- Check wiring of all actuators, that are connected to lowsidedriver #1 (lowside has short to GND ?) - Replace the ABS-ECU module, if the wiring is faultless
What you'll see
No driver-visible symptom recorded.
System reaction
ABS function is still available. ATC engine control is still available ATC brake control is still available HSA is not deactivated EBL is not deactivated Drag Torque Control is not deactivated
Diagnostic depth
Detection
A short circuit to GND on the lowside driver line (LD1/Dif-OV) was detected. Remark: If at least one actuator (connceted to LD1) is currently activated, then the GND short-circuit detection will not be executed.
Possible cause
- faulty wiring of actuators, that are connected to lowsidedriver #1 - ABS-ECU defective
