10 Point Expert Question - AL4 Fault Code: 87 - 307

Error code: 87 writes.

When there is 87 error code, what to do and where to look. The error details are below.

error: automatic transmission calculator: Remote Continuous Error: Vehicle speed given by ABS (Can) No signal.

error: remote intermittent fault. vehicle speed transmitted by the ABS (CAN). NO SIGNAL

I just guess, I don't know the subject in detail, but;

Can it be a crank speed sensor?

Could there be an abs sensor in the podye, that is, in the wheel? I know it is the device that reads the wheel slipping because the names of the errors will remind me of it, and there will be some people who can give exact information.

I think the chronic abs sensor error sensor should be checked.

Wouldn't ABS Brain Ecuda say the sensor of that wheel if there was a sensor error?

Also, my speedometer on the console is working properly. The vehicle speed is normal when it connects to the computer with PP200 and looks at the parameters.

My guess is that the cable from ABS Brain to BSI has no problem, so the speed seems normal. However, there is a problem with the cable or signal from the ABS Brain to the AL4 automatic transmission ECU, so only the AL4 Automatic transmission ECU is failing water.

However, the error code it gives is not the standard OBD / EOBD code.

He wrote a code called PSA 87. But at least they have the explanation, they said that the vehicle speed cannot be taken from ABS.

Now I need a circuit diagram AL4 ECU which pin gets this signal. Which cable should I check?

Already the abs sensor has nothing to do with the speedometer or the flasher, that sensor is the part of the wheel that enables the activation of the abs in the wheel (drum).

I encountered a similar malfunction in the 2000 model Scenic vehicle. The transmission is the same in scenic. In Scenic, the AL4 transmission speed is read from the ABS sensor on the right front wheel. Since my vehicle could not read the speed, the gearbox was not allowing the vehicle to move, silencing the engine. we lifted the vehicle and started the engine. when working at idle, the right wheel is 1 mm. When we turned it, the engine was silent. If you don't move the right wheel, it would continue to run at idle.

Our problem occurred after the rainwater filled the vehicle as a result of the obstruction in the sunroof expenses of the vehicle. It was originally said that the ABS brain will change. While we were researching to find the ABS brain out of bulgaria, while waiting for the car in the repair shop in the past 2 weeks, the floor covering has dried up and the malfunction lamp warning has disappeared. ( There are cables and connectors passing under the floor covering on the right side of Scenic ). Then we cleaned the sunroof expenses and when we prevented the vehicle from getting water, we did not encounter this malfunction again. If water has got into your vehicle in some way (calorie radiator may be leaking), it is useful to perform under floor moisture control to eliminate the malfunction.

Good luck with.
