Check the engine light on the Toyota Tundra and use the Jaltest diagnostic software to scan engine systems and know the cause of the malfunction. The other option is to book a dealer appointment and take your vehicle for servicing.
2. Maintenance Required
This is an important part of the range of Toyota Tundra warning lights and comes on to alert you that maintenance services are required. The symbol reads MAINT REQD, will light up for three seconds, and flash for 15 seconds before turning off. This cycle will carry on for 4500 miles and is a constant reminder that your vehicle is due for servicing.
3. Low Oil Pressure
Typically, Toyota Tundra oil must be changed after every few thousand miles. If you go beyond certain limits a light will go on like the shape of an oil can. It is an indication that the oil pressure is running low and if you choose to put off this servicing, it might cause irreparable damage to the engine.
4. Tire Pressure Warning Light

6. Engine Temperature Warning Light
Keep an eye on and check the engine light on Toyota Tundra which indicates that the engine temperature is rising and high. It shows that the engine temperature is very high and the engine needs to cool down. It is not only continuous driving or high outside temperatures that might trigger this warning, some of the other reasons are mechanical issues, low coolant levels, and lack of oil. If this happens, stop and have your vehicle towed to a local service station.
7. Battery Warning Light
This is among the key Toyota Tundra warning lights and tells you that the battery needs attention. It is very critical as not only do you require a charged battery to start the vehicle but also to turn on the headlights and side lights. This light popping up means that the alternator is no longer charging the battery and it is running on the power stored in it and will soon run low. The option here is to replace the battery yourself and get the alternator working again.
8. ABS Warning Light
There may be several issues if the ABS or anti-lock warning light goes on. Among the main ones are low fluid levels, ABS system is turned off, malfunctioning ABS module, broken wheel sensors, and more. It is not easy to diagnose the main cause and hence, use our Toyota Tundra diagnostic software or take your vehicle to the nearest service station to get to the root of the problem.
