Resetting fault codes [Toyota Carina T190]

1. After repair, clear the memory of the automatic transmission control unit from the fault codes stored there. To do this, remove the "EFI" fuse for 10 or more seconds, depending on the ambient temperature (the lower the temperature, the longer) with the ignition off.

Attention:

• - To reset the fault codes, disconnect the negative battery terminal for a while. This will erase the memory contents of the control units of other systems.
• - To reset fault codes, disconnect the automatic transmission and engine control unit connector.
• - if the fault code has not been reset, it will be stored in the control unit memory and will appear during subsequent diagnostics.

Table. Error codes (continuation). A540N.





*: for models up to 1996.

Note: codes 62, 63, 64, 73, 74 indicate a fault in the electrical part of the electromagnetic valves. Faults in the mechanical part, such as valve sticking, are not recorded by the self-diagnosis system.

2. After resetting the codes, check that the flashing of the upshift indicator should correspond to the normal state of the gearbox.
