Erasing may also be done by disconnecting

Erasing may also be done by disconnecting the negatively-(-) terminals on the battery accumulators reflex. But this case other e system with "memory" (radio, clock, etc.) as "clean."
- If the diagnostic code is not erased, then it will remain in the pas ¬ myati electronic control unit of ¬ and will be shown together with the new code when a new fault.
- If necessary, switch-off radiation (removing) the battery is the need to first read the fault codes.
2. After erasing operations necessary tofulfill Dimo-road test and make sure that the code is "normal operation, you" will be displayed warning lamp "CHECK".
If the same diagnostic code will be displayed again control lamp "CHECK", this means that (repair work carried out non-satisfactory.
Display diagnostics
1. The electronic control unit includes fault codes listed below (see table), and among them - the normal code work.1 engine.
2. If at the same time are the appearance of two or more types of faults, it is primarily excreted in the code having the smallest number, and more - with the growth numbers.
3. All trouble codes, zafiksi-mounted in the driving cycle, except for:
code number 51 (4A-FE, (AE92, AE95, AT171 and AT180) and 4A-GE (AE92 and AT160) code number 16, 43, 51 and 42 (5A-PE (AE110), 4A-FE (01 and AE1 AT190). 7A-

Erasure
diagnostic code
1. After repairing a failed node diagnostic trouble code stored in the memory of electronic control unit of ¬. Therefore, it should be removed (erased) by disabling the following fuses (with ignition off):
"5T0R" 1 5A (all AE, except AE101), "EF1" 1 5A (All antibodies AE1 and 01). Fuses are located in the distribution predelitelnoy box. From time-trial (at least 10 s) depends on the ambient temperature (the lower the temperature, the longer before the guardian must be turned off). Arrangements of the fuse on the various models listed below.
4. After troubleshooting the fault codes are not output with a test lamp "CHECK", but will remain in the memory of the electronic control unit, for, except number of codes is listed ¬ GOVERNMENTAL in the preceding paragraph.
