Output of diagnostic trouble codes
Attach a special tester to the diagnostic socket.
The figure shows a typical tester for displaying automatic transmission fault codes.
A - to the cigarette lighter;
B - to the diagnostic connector.
Read diagnostic trouble codes. Then do the troubleshooting.
Diagnostic recommendations
Up to 10 diagnostic trouble codes can be stored in the control module (in the order they appear).
The same DTC can be stored up to three times.
If the number of stored DTCs exceeds 20, the DTCs already stored are cleared in sequence, starting with the oldest.
Do not disconnect the battery until all DTCs or DTCs have been read, as disconnecting the battery will clear all stored DTCs.
