Diagnostic Trouble Codes
Diagnostic trouble codes (DTCs) are logged in the ECM
memory when there is a confirmed fault in the system.
The codes are reported to the Triumph diagnostic tool as
a four digit code, as required by California legislation.
As mentioned earlier, when the system detects a fault, it
begins to count the number of times the fault occurs
before illuminating the MIL and storing a fault code.
Similarly, if a fault clears, the ECM also records this fact
and will turn off the MIL when sufficient no-fault warm-up
cycles have taken place. Any fault codes will remain in
the ECM memory until the required number of no-fault
warm-up cycles have taken place. The number of
warm-up cycles required to extinguish the MIL will
always be less than the number required to remove a
DTC from the ECM memory. DTCs can be removed at
any time using the Triumph diagnostic tool
The system will log the diagnostic trouble codes listed
