Information about combined diagnostic trouble codes (DTCs) (B5234T3; B5244S; 2001-2004)

Combined diagnostic trouble codes (DTCs)

The following table is available to facilitate fault-tracing of ETM related diagnostic trouble codes (DTCs).

Note. Probable root diagnostic trouble codes (DTCs) are in bold and listed at the top of each cell.

Example of how to read table: If the codes 902A 903F 912A 980F are set, then 902A is the likely root trouble code.

The diagnostic trouble codes (DTCs) can also be stored individually or together with other diagnostic trouble codes (DTCs) that do not affect ETM.

Note. There are two different tables, one for cars with upgraded software released during 2006 or later, and one for cars that are not upgraded with this software. See Identifying upgraded software ECM/ETM
