2009年7月29日 · I believe N70b1 is malfunction. I talked to MB Part Dept. (dealer) and was told that have to replace entire overhead console ($485). Does anyone know if that true?

2024年8月31日 · I’ve managed to locate that AC module sees about 97oC signal from OCP and 23oC from dash sensor. Going to the OCP module, the sensor itself senses good temperature. Confirmed it with diagnostic and physically. Something is wrong with the communication between these two modules, does anyone have a diagram?

today we fix one of the most common HVAC system problems in the w220 and w215 with the In Car Temperature Sensor (N70b1) in Overhead Control Panel (OCP) (N70...

2011年8月4日 · Otherwise only the sensor in the Overhead Control Panel control module (N70b1) is read. I think that you should first try the A/C reset procedure. "To reset the unit, start the engine and hold down the demist and recirculation buttons for > 5 seconds, if successful both LEDs flash and the unit will cycle the flap motors to normalise their position"

Used in conjunction with the 2 interior temperature sensors for improved cabin temperature regulation. The two in-car temperature sensor values are averaged unless the outside temperature sensor (B14) is reading under 50°F, then only the N70b1 is used for cabin temperature regulation.

Parameter NR.01: In Car Temperature Sensor (N70/b1), ACC Overhead Control Panel (OCP) (N70) should indicate the in cabin air temperature near the roof of the vehicle, eg 27C. If it reads 0C and the cabin is not freezing then there is a fault. The solution is to test the thermistor and aspirator function and then if necessary replace it.

Anyone know where the 974 n70b1 integrated fan temperature sensor is located on a glk350? I found the one in the upper light console and the one near the...

2012年1月18日 · (N70b1) and (N22b1) The two in-car temperature sensor values are averaged unless the outside temperature sensor (B14) is reading under 50°F, then only the N70b1 is used for cabin temperature regulation. An open sunroof in this case can cause excessive heating complaints due to cool air swirling around N70b1. Read here for the whole story...

The overhead control panel control unit reads sensors and switches and controls their functions. Depending on the requests received, consumers are switched or supplied with voltage and signals are transmitted or received via CAN-B.

2019年3月14日 · Опыт эксплуатации Mercedes-Benz C-Class (W204): Отказался работать датчик температуры салона N70b1, показывал температуру -128°С, потеря связи с шиной can.Разобрал плафон, сам датчик с кулером, насосал пыли ...
