RE: FAULT ABS RENAULT LAGUNA 2
THIS IS FOR VDIAG 08 & 0C
check the car if has System equipped with Electric Brake Assist Emergency
check parameter screen PR041 and tell which is A0,B0,D0,E0 E1
if yes is A0,B0
Check the condition and correct connection of the servo plug.
Check the connection and condition of computer connector and 6 contacts to the servo.
Check to ensure electrical continuity at the following links:
- Connector 4 servofrenouepafi contact 17Fis computer
- Connector 3 servofrenouepafi contact 31Fis computer
Ensure also the insulation between these connections.
Visually check the wiring of the brake booster.
Check the resistance of servofrenouR = 2 Z. If the resistance is not correct, replace the servo.
Ensure that no voltage + 12 V after mains switch on the brake booster between the contact 4 and body.
If the voltage is incorrect, contact the Technical Support Department (Techline).
If all checks are OK, reconnect the computer and the servo and then turn off the faults of computer memory.
Replace the SERVO if the fault reappears.

If I've helped, please press Thanks [Image: v7b9s8.gif]
