Symptom: a 2003 motor vehicle factory in Guangzhou Honda Accord 2.three L sedan (with computerized transmission), since the speedometer and icom a2 odometer around the dashboard doesn't show by a fix store diagnosed odometer ruined, but buying a new instrument from the overall soon after loading in to the examination, speedometer and odometer still not shown.
Troubleshooting: Very first road take a look at, speedometer and odometer pointer Liquid crystal display counting technique don't work, however the engine is operating tech2 scanner> typically, the automated transmission equipment jump is usually typical. Take out instrument complete Qi, located with out unplugging wires side connector pace sign input terminal (blue / white), driving with the analog signal generator (Expo 8901 Desk), speedometer pointer reveals the pace and mileage counter is running. The overall ring mounted instrument replaced within the check, but will also ordinary. Preliminary judgment instrument assembly should be no problems. A fault need to arise in the auto velocity sensor or maybe a car pace signal lines. Entry to information which the iobd2 reviews vehicle speed sensor ought to be a few terminals Corridor, but did not come across searched the motor compartment on the sensor. As the car or truck is supplied with multi-channel transmission methods, I do not know irrespective of whether the motor vehicle velocity signal from your Abs or automatic transmission technique.
Remove the multiplex command unit is located to examine the driver's facet dashboard, also observed no abnormalities. The auto velocity is found to generally be according to the colour of the line input signal traces for the terminals B14 multiplex transmission management product. In desperation, once more refitted superior detection unplug the wire aspect on the connector, hook up the fault maxidas ds708detector, the climbing military services automobile lift, study data stream, then observed a noteworthy phenomenon in the info stream wherever can read through the pace signal, hold up the D block, the velocity sign benefit might be greater with expanding throttle opening, auto pace sign which implies that previously have into the motor electronic management unit, there's no have to go looking for your so-called a car speed sensor. But why not exhibit speedometer and odometer Nick? Check out moving into automated transmission and anti-lock braking method, the program can be able to read the velocity sign.
