Mode 2
Mode 2
In mode 2 the operating conditions (freeze frame data) at the time of fault entry are displayed. The operating conditions of the fault which occurred first are stored. If a fuel system fault or misfiring fault occurs after this, the data of the fault which occurred first are overwritten.
The following PIDs are supported:
$00 Supported PIDs
The PIDs supported in this mode are displayed in a 4-byte word.
NOTE: If there is a fault, not all supported PIDs are stored in the memory, but only 6.
The Data A and B bytes indicate that PIDs 02, 03, 04, 05, 06, 07, 08, 09, 0C and 0D are supported. From these supported PIDs, the 6 most meaningful ones are stored for one fault.
$02 Diagnostic Trouble Code
The Diagnostic Trouble Code which caused the storage of freeze frame data is displayed.
$03 Status of injection system
Data:
A: 0000 1000
B: 0000 1000
Data A - Status of bank 1
Data B - Status of bank 2
NOTE: Only one bit at a time can be set to 1 to indicate the status.
$04 Calculated load value
Output of calculated load as a percentage of the maximum load.
Display between 0% and 100%.
$05 Engine coolant temperature
Output of the engine coolant temperature.
