    Hello!

    Well, I have a problem with ABS in Laguna II 1.8i, after starting the engine does not go off ABS and handbrake control.
    Errors: C1131 and C10C0: brake pressure sensor, no controller power supply, voltage too low.
    All relays, fuses, contacts have been checked, the power supply on the ABS block is coming.
    What do you think? An ABS pump in? Or maybe the system itself at the pump?

    The ABS pump is released. Replacing the electronics itself will not do anything. You must replace the entire pump.

    I will dig out the topic I have Lagune II 1.8 16v from 2001 and I have exactly the same problem and error C1131 which I can not remove of course, the ABS indicator light and the hand brake light what was the cause of the fault whether it is actually ABS pump pozdr

    The driver itself can be replaced.

    The ABS pump module usually has three pluses. And the power to the minus, which are also to check.
    And the fact that the brake pressure sensor error comes out does not always mean its failures. You need to analyze the actual values in the Abs steering wheel

    Once in the skins superb I had a brake pressure sensor error. The error was canceled, but after pressing the brake pedal appeared. In real terms the pressure was good and the stop switch turned out to be guilty. I tested KTS, but I doubt that he misinterpreted the error

    the small difference here is not canceled, you were canceling, and because it was good, only the system did not see that you pressed the pedal and the pressure increased.

    Well, that's ;)

    So the replacement pump can be regenerated or is it not better to replace it better?

    The topic is supposedly over, but I had a similar case. Laguna II FL. Error slightly different C1113 - ABS Power Relay Coil Short Circuit To Battery.

    Clearing the error did not help, after a while the error was active again. I took the ABS/ESP pump apart and there the pistons that drive the motor were blocked. I started it up, cleaned it, etc.
    After bleeding the brake system, the error disappeared. Everything is working properly.
    Jamming of these pistons in long-standing pumps is apparently a fairly common occurrence.

Topic summary

The Renault Laguna II 1.8i exhibits persistent ABS and handbrake warning lights after engine start, with diagnostic trouble codes C1131 and C10C0 indicating brake pressure sensor faults and low voltage/no controller power supply issues. Despite verified power supply and intact relays, fuses, and contacts, the ABS pump is often identified as the root cause. Replacement of the entire ABS pump assembly is generally recommended, as replacing only the electronics or driver module may not resolve the issue. The brake pressure sensor error does not always indicate sensor failure; it may result from system misinterpretation or related components such as the brake light switch. In some cases, mechanical jamming of the ABS/ESP pump pistons can cause similar errors, which can be resolved by disassembling, cleaning, and bleeding the brake system. This piston seizure is a common failure mode in long-used pumps. Regeneration of the pump is possible but replacement is often preferred for reliability.
