Mode 2



Mode 2
The following PID's are supported in Mode 2:

$00 Supported PID's
The PID's 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 PID's are stored in the memory, but only 6.
- The Data A and B bytes indicate that PID's 02, 03, 04, 05, 06, 07, 08, 09, OC and OD are supported. From these supported PID's, 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

Mode 42Pid$03 Adr$17
Data A Data B
00001000 00001000

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.
