Toyota Hilux fault codes
Toyota Hilux fault codes list
Fault codes of petrol engines (Toyota)
The self-diagnosis codes are read by the number of flashes of the indicator “CHECK ENGINE” with the closed terminals “TE1” – “E1” of the DLC1 connector under the hood or “TC” – “CG” of the DLC3 connector under the dashboard and the ignition on. The DLC2 connector is also closed in it “TE1” – “E1”.
If there is no malfunction, the indicator flashes at 0.25 second.
If there is a malfunction, the indicator gives the beginning of the tens in 0.5 seconds, then a pause of 1.5 seconds and a unit with a pause of 0.5 seconds.
In the presence of two or more codes, a pause between them is 2.5 seconds.
After the output of all codes, there is a pause of 4.5 seconds, and then the codes are repeated.

SRS Fault Codes Toyota Hilux

Erasing codes must occur when the ignition is switched off. If the codes are saved, you need to perform the cleaning procedure:
– connect two wires to the terminals “TC” and “AB”
– switch on the ignition and wait at least 6 seconds
– alternately, once per second, connect the terminals “TC” and “AB” (the pause between the closures is less than 0.2 seconds)
– after the third closing of the output “TC” the indicator should blink at a high frequency – the codes are erased.
