E46 K Bus Wiring Diagram

This is a great place for the arduino interface as the connector provides a +12v wire, ground, and the k. • voltage supply to th3122

Do a complete test of the car.

E46 k bus wiring diagram. Do a continuity test with each wire and test to see if it was jumping to ground. • intro • technical details • schematic description • resources & downloads • programming • integration • messages tags: The cvm module is on that bus.

Lower the fuse box to gain access to the k line hub. The three i will write about are: The cd changer is an optional unit on most cars, but the wiring is typically there even if you do no have the actual cd changer.

After the procedure the k bus came back, and the car is back to normal. Start plugging each module one at the time to narrow it down to a single module (no luck) results: 1) detect rain on the windshield to automatically turn on the wipers and set a proper wiper speed 2) detect ambient lighting to control automatic headlight operation

The rc filter minimizes emi on the bus line, and is recommended per th3122 datasheet. Then in your case the k bus is down. If the bus is sitting at anything less than 12v then.

One trick often performed by pros: The entire bus was down as a result of the bus having a pathway to ground. The rubber cap that you are holding is a factory insulation sleeve at joint no.

With the k bus diagram, remove one module on the bus. If anyone could send me a copy of an e46 instrument cluster wiring harness diagram it would be greatly appreciated!! The rain/light sensor is mounted on on the top center of the windshield.

X18355 they use for jointing similar wire together (they don't use solder). Hook up a factory level scan tool. Disconnect and label all of them.

It should be +12v or so with occasional low going blips. Jul 23, · bmw lcm 4 high beam driver ic replacement elektronik_freak. In other words, it is a way for devices within the car to communicate with each other.
