Nissan addressed the root cause of those problems and upgraded the transmission. Luckily, Nissan would go on to address most of those concerns. Even the most recent Nissan CVT transmissions are failing early and often. The problem is so serious that Nissan was forced to slash its profit outlook on April 29, to reflect falling sales and rising CVT transmission warrant costs. Nissan CVT transmissions are known to run hot and cause premature failure.
Some speculate that the cause of the overheating is undersized cooling systems. Reports from owners show that Nissan CVT transmission fail, on average, at about 64, miles. Not really. They include wiring diagrams and technical service bulletins. In most cases, their diagrams are right from the factory manuals. Pricing: Eautorepair. So you have to refer to the factory legends to learn the identification symbols and then refer back to circuit diagrams to find the splice and ground locations.

Here is an example while towing up the steepest part of the hill in second gear. But I have installed a large after market cooler so that helps keep the temps down. If you tow with the normal tow package cooler, you need to monitor your trans temps. Last edited: Oct 7, RyanDCLBkairojya16tacoblue and 1 other person like this.
Do you use pan or post converter temp reading to check automatic transmission fluid level? Hank HeelOct 4, Should Ask mod to add these into the 3rd get maintenance diy thread, deductive reasoning dictates that diy folk would appreciate this.All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
Manufacturers also define additional PIDs specific to their vehicles. BeforeJ referred to these services as "modes". They are as follows:. Vehicle manufacturers are not required to support all services. Each manufacturer may define additional services above 9 e. The expected response for each PID is given, along with information on how to translate the response into meaningful data. Note that services 01 and 02 are basically identical, except that service 01 provides current information, whereas service 02 provides a snapshot of the same data taken at the point when the last diagnostic trouble code was set.
If service 02 PID 02 returns zero, then there is no snapshot and all other service 02 data is meaningless. Each bit is numerated from 0 to 7, so 7 is the most significant bit and 0 is the least significant bit See below.

AB is two's complement signed . Service 02 accepts the same PIDs as service 01with the same meaning,  but information given is from when the freeze frame  was created. Some of the PIDs in the above table cannot be explained with a simple formula.
A more elaborate explanation of these data is provided here:. A request for this PID returns 4 bytes of data Big-endian. For example, if the car response is BE1FAit can be decoded like this:. The first byte A contains two pieces of information. The second, third, and fourth bytes B, C and D give information about the availability and completeness of certain on-board tests.
Note that test availability is indicated by set 1 bit and completeness is indicated by reset 0 bit. The third and fourth bytes are to be interpreted differently depending on if the engine is spark ignition e.
Otto or Wankel engines or compression ignition e. Diesel engines. In the second B byte, bit 3 indicates how to interpret the C and D bytes, with 0 being spark Otto or Wankel and 1 set being compression Diesel.
A request for this PID returns 4 bytes of data. The first byte is always zero. The second, third, and fourth bytes give information about the availability and completeness of certain on-board tests.Automatic transmission failures are usually a result of overheating.
The main culprit for this is low transmission fluid. The normal transmission temp is degrees but with overheating, it could rise to over degrees. This then leads to hardening of seals, and they soon start to melt slowly. At degrees, your plates will slip, and any further increase in temperature leads to clutch burn out, and your transmission fluid will form carbon. It is vital that you constantly monitor the normal transmission temp to help your transmission to have a longer lifespan.
The gears inside the transmission rub against each other, and this results in a lot of friction being generated which turns to internal heat. Every time the transmission temperature rises above the optimal level, the lifespan of the transmission is cut rapidly.
The ideal temperature for an automatic transmission is around degrees. Cars often have the coolant for the engine as a heat exchanger for the transmission fluid and therefore, they will often hold the same temperature if you are driving it normally. However, if your transmission is slipping a lot or you are pulling something heavy, the coolant may not be enough to cool the transmission efficiency and the temperature may rise drastically to temperatures over degrees. The older automatic transmission may not use coolant lines to the transmission, and these are even more sensitive to high loads.
Most cars do not have an external temperature gauge for the automatic transmissions fluid. Instead, they use a warning light or the check engine light to show when the transmission is overheated.
There are some different reasons why your transmission may overheat faster than usual. Here is a list of the most common ones.Displayport only showing 60hz
If you are using old and worn transmission fluid, your transmission can slip more than usual. The fluid can get contaminated with time, and this affects its operation. You should immediately drain the old fluid and purchase synthetic fluids that are thought to last longer. The solenoid plays a critical role in regulating transmission fluid flow. When it is defective, you have less of the fluid flowing to the transmission, and this can cause overheating.
You may need to evaluate the circuits in the solenoid to determine whether it can be fixed or whether you need to purchase a new one. You need to check your transmission fluid with a dipstick sometimes.Play Now. Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors.

Any information is appreciated. Repair Importance Level: 3. Home - About AutoCodes. Posted and Edit by AutoCodes.The arrival of electronic computers to manage the engine and associated computers enabled vehicles to reduce their pollutants. The OBD states that a vehicle should permanently monitor the smooth operation of the engine throughout its life. It states that emission failures must be signalled by means of an indicator on the dashboard and that the codes corresponding to the detected failures must be recorded by the vehicle.
Some vehicles not covered by the directive may nevertheless be compatible. It depends on how much manufacturers are in advance of the new directive and their willingness to implement the standard. Euro 3 and its directive announced the arrival of a new indicator on vehicle dashboards.
Opposite are some examples on various vehicle models. This indicator is used to signal a problem in the vehicle's pollution control system. Depending on the faults, there are several possible modes of operation:. The directive states that the connector must be placed inside the passenger compartment. Usually it is located under the steering wheel in the fuse box or under the ashtray near the handbrake.
If you cannot find your diagnostic connector, go to our page location of OBD connectors to help you locate it. Front view of the vehicle connector here a Dacia Logan.
PS: It should be noted that the remaining pins may be used by the manufacturer as needed. While the port is standardised, several communication protocols remain possible depending on the manufacturers. It is the job of the software in the ELM interfaces to decode these various communication standards. The protocols described below all use the same medium same electrical connection.
However, differences in the data sent mean that they are not compatible with each other. This protocol is used mainly by European manufacturers. Within this protocol, there are 2 "sub" protocols that differ mainly in their level of initialisation: slow init or 5 baud init and fast init.
This protocol is mainly used by Ford. This is the protocol that will ultimately be used by all vehicles. It offers the best rapidity and flexibility. This protocol is mainly used for heavy duty vehicles trucks, agricultural machinery, site machinery. Most often, the diagnostic connector is not the same on this type of vehicle, and looks like the one above. Whatever the protocol used, the OBD defines 10 modes of diagnostic.
The more recent your vehicle, the greater the chance of it supporting more modes. The following page list of OBD2 compatible vehicles gives some examples of vehicles tested by users. Each sensor is characterised by a number called PID Parameter Identifier used to identify the parameter. For example, the standard stipulates that the engine speed has a PID of As for the modes, not all cars support all PIDs. This mode gives the freeze frame or instantaneous data of a fault.
When a fault is detected by the ECM, it records the sensor data at a specific moment when the fault appears.
This mode shows the stored diagnostic trouble codes. These fault codes are standard for all makes of vehicle and are divided into 4 categories:. More details and the definition of the generic fault codes are available on our page Standard OBD fault codes. Mode 4 This mode is used to clear recorded fault codes and switch off the engine fault indicator.
Note : mostly it is not necessary to clear a fault that has not been diagnosed or repaired. The MIL will light again during the next driving cycle.
