Error: "check awd system, trc system is not working" on toyota rav4.

Greetings, friends!

Today I will tell you about a recent incident with my car. As usual, after warming up, the car began to move from the parking lot after 10 minutes, stopping at an intersection, I heard a sound signal from the dashboard and saw that the error “TRC system is not working” popped up, and also the “Check Engine” icon lit up on the panel.

Error code: Where is the diagnostic connector on the Lada Vesta?

I found in the manual that to turn on the TRC system you need to press the button on the panel on the left side.

But when I pressed this button, a new message “Check AWD system” appeared. The first thing that came to mind was to remove the terminal to clear the error. This action did not help.

Here I got a little worried, because after reading on various forums the assumptions were not reassuring.

Some wrote that it was necessary to look at the spark plugs, the engine, the fuel pump, others that it was something with a variator, and many more assumptions. They suggested going to an official dealer, but we are not looking for easy ways.

I read in one of the posts that such glitches can occur along the power supply line. You could check this on your own, which is what I did.

As a result, the reason was found; it was simply a 7.5 A fuse number 14, responsible for the reversing lights.

After installing the working fuse, you must reset the terminal again to clear the errors.

After this, the errors no longer appeared. I will be glad if this information helps you.

Should I continue driving if my Lexus check engine light comes on?

Since the check engine light won't tell you much, deciding whether you should continue driving or not can seem difficult.

Watch how your car behaves and look for symptoms such as:

Engine misfire or vibration

Poor gas reaction

Any of these signs indicate that the engine in your Lexus is not working properly.

Start looking for a safe place to stop, as driving like this can easily cause permanent engine damage. We recommend that you avoid driving the vehicle if you notice performance problems, overheating, or engine shaking. Driving your Lexus with these systems can lead to costly engine problems.

Analogues for the U660E, U760E box

Also for this automatic transmission, you can select high-quality analogues of the original transmission fluid, characterized by high quality and compliance with the manufacturer’s requirements.

Hello. 2013 Rav4. At a speed of 140 km/h on an air-conditioned highway, there were two shocks and a loss of torque transmission. The message “automatic transmission oil overheating” appeared and part of it was thrown out. Then, in tow with the engine running, we reached the city, 70 km. Adding oil did not solve the problem; the car jerks in any forward gear. At idle engine speed a whistle is created, when towing over 15 km/h, it disappears. What happened? Mileage 170,000 km.

Good afternoon Alexander! It looks like there is a malfunction in both the mechanical and hydraulic parts of the automatic transmission. What was the root cause is still difficult to say. For an accurate assessment, perform an initial diagnosis of the automatic transmission at a specialized technical center.

Good afternoon Tell me, what could it be? The car drove without jerking and without any dullness. But one day, after a trip of 50 km, I felt that the traction was gone. I stopped, put it into park, then back into drive, and when I released the brake pedal the car did not start moving. I gave a little gas and tried to drive. I switched to reverse speed - the same story, but when I gave a little gas, there was a slight kick and the car went into reverse. After switching to drive, the car drove forward as normal. Having reached the house (about 2 km), I stopped to open the gate and drive the car. History repeated itself - after engaging reverse gear there is a kick, then in drive the car goes forward. After stopping, I move the speed knob to different ranges and hear a crackling sound, as if running a fingernail along a comb. I turned off the engine, did not use the car for a day, then I started it, changed the speed, I no longer heard crackling sounds, but in the drive and reverse positions, I felt that the transmission was straining more than necessary. Begins to move, without early symptoms.

Selecting oil for automatic transmission Camry 40

Among all generations of the Camry model range, the sixth or XV40, which is so loved by our compatriots, is distinguished by its reliability. But at the same time, not everyone knows what kind of oil is needed for the automatic transmission of the 40th Toyota. Most modern motorists purchase transmission lubricant on the principle of “universal for the box”, without paying attention to the brand of the product itself and the model range of the car.

Engine V6 3.0 1MZ

For Camry 40, you should select the lubricant recommended by the manufacturer. Such information is indicated either on the dipstick or in operating conditions. The ideal oil for Toyota automatic transmission is Tipe T-IV, developed specifically for the holding’s cars. The original WS will also work. If this lubricant is a little expensive, then you can choose one of the analogues:

• Dexron 2;
• SP 2;
• Mopar 7176.

However, their cost is also not cheap, especially when you consider that to completely replace the consumables, you need to prepare 3 canisters of 4 liters each.

Engine 2.4 2AZ

Also on the Camry, a traditional or partial update is allowed, in which the filling volumes and replacement interval are such that the procedure itself is more expensive. Not all motorists perform such activities with the same frequency, but if we take the average, then with 30 thousand completed, “topping up” will use up about 10 liters.

How often do you need to change the automatic transmission oil in a Camry?

Manufacturers do not indicate how many kilometers are needed to replace the lubricant in an automatic transmission, indicating that it and the unit have the same service life. But actually it is not. Manufacturers' recommendations are suitable for ideal foreign roads. Our compatriots should update the Camry's transmission lubrication every 40 - 50 thousand km.

But you should not blindly focus only on mileage, since after 10-20 thousand km malfunctions may occur due to lack of lubrication in the box. And if you wait until the car travels the same amount, then the motorist will have to fork out for expensive repairs to the Toyota Camry automatic transmission.

For this reason, you should change the oil when:

• It will be useful to warm up the transmission for a long time in cold weather;
• when switching from gear to gear, a hum or extraneous sounds occur, as well as jerking and other difficulties;
• engine power decreases;
• the lubricant level is below normal;
• The lubricant has darkened and acquired a burning smell.
