Mode 2

Mode 2
In made 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 over- written.
The following PIDs are supported

$00 Supported PIDs
The PIDs supported in this mode are displayed in a 4-byte word.

Data A:

Data B:

Data C:

Data D:

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







Bit 0 - Open-loop control, the conditions for closed- loop oxygen sensing have not yet been satisfied.
Bit 1 - Closed-loop control, the signal from the oxygen sensor is used to control injection.
Bit 2 - Open-loop control through conditions such as full load, etc.
Bit 3 - Open-loop control through faults in the system.
Bit 4 - Closed-loop control, but faults from at least one oxygen sensor.
Bits 5 to 7 not used.


NOTE: Only one bit at a time can be set to 1 to indicate the status.
