ABS Light On: Troubleshooting & Solutions

Hi everyone,

The ABS light has been on in my car for a while now.
The error log showed intermittent faults for the front left and rear right sensors.
Okay.
Then, eventually, a permanent error.
Both sensors have been replaced.
Still not okay.
Vo Re still has a bug.

Then I bought a new sensor again and installed it.

Unfortunately, there is still no improvement.

Control unit part number: 1J0 907 379 G.
Component and/or version: ABS 20 IE CAN 0001
Encoding: 03304
Workshop code: WSC 00046.
"One error found:"
00285 - Front right speed sensor (G45)
35-00 - -

What else can I do?

Best regards,
Sascha.

...check all cables and connectors (between the control unit and the sensor).

And that doesn't just mean "watching," but actually testing it with a continuous, uninterrupted run.

Okay, here's the translation:

"Good answer."
Why didn't I think of that myself...?
Sometimes, when you're looking at the forest, you can't see the trees.

What should the resistance values be?
"It's not that the cable is broken, but that the resistance is incorrect, and I'm worried about getting electrocuted."

Best regards,

Hello bakkano,

"Just pinging it is enough; the cables from the control unit to the sensor are simply connections."
Aber schau mal ob der Stecker auf dem Steuergerät richtig sitzt. Please pay particular attention to this.
"Check if there is any moisture inside the large connector on the ABS/ESP control unit."
I don't know what kind of vehicle you have, but there have been occasional problems with...
"Flooding" from such connectors, and then there were interactions due to leakage currents between the many pins.

Here's another thing: Some ABS/ESP control units only turn off the warning light after a diagnostic fault (DF) if they receive a valid wheel speed signal again. This means you may need to briefly drive the vehicle (above 20 km/h) and then perform another ignition reset.

I hope you find the problem.

Don't forget to check the ABS wheel speed sensor. If this part has missing teeth, is bent, or is covered in rust, it won't produce a proper signal.

Sure, here's the translation:

"Guste" is a German word that means "gust" or "gust of wind." It can also be used to describe a sudden burst of something, such as laughter or anger.

Copper paste from the brakes, grease from the driveshaft boot, and road grime are also commonly found contaminants.

Thank you for the answers.
Fortunately, the problem has been resolved.
It was a direct cable break at the connector itself.
The sensor and other components are working correctly.

Sascha.
