<\/p>\nHello, everyone,
\nI want to share with you a case that happened to us recently and that may be useful in the future.
\nThe car had just come out of the body shop after a reverse collision with a light pole. After the repair, it arrived at the workshop to fix the various faults remaining on the panel.
\nAt first diagnosis, an endless list of errors appeared on radar, anti-collision, ABS\/ESP, PDC, etc...
\nAmong the various codes was this one: B120A - Collision risk alarm function deactivated.
\nEntering BSI, we tried to re-enable the deactivated functions, but the procedure failed with two different diagnostic tools.
\nThere were also anomalies on the vehicle speed signal. Only two 'mysterious' codes appeared in the ABS\/ESP diagnosis: C0514 and C0515, without description.
\nChecking the parameters in real time, it could be seen that the right rear wheel (when the car was stationary) did not show 0 km\/h but only the three dashes '- -'.
\nWe then proceeded to check the sensor and the hub, both of which turned out to be OK. Eventually we found the break in the wiring: the wire was damaged due to rubbing against the corrugated protective sheath. It was probably not a direct consequence of the impact, although the accident may have made the situation worse.<\/p>\n
After re-establishing the connection and completing the procedure to reactivate the post-impact driver assistance systems, everything worked properly again.
\nI attach a picture of the exact spot.
\nI also invite all of you to share your solved cases! Every experience you tell can help a colleague who will be faced with the same problem tomorrow.
\nIt is not 'giving away your work', but growing together.
\nPerhaps I was a little long-winded in writing ;-) but it only takes a few minutes...<\/p>\n
