2-2-7. PCB Version Control
The presence of resistors mounted on particular PCBs enables version control of engine control PCBs.
7 6 5
Example of Implementation of Resistance
7 6 5
In this example of implementation, there is resistance
at the 0, 1, 3, and 5 positions. Thus, the version is 43
because 1+2+8+32=43.
2-2-8. Precautions During Engine Control PCB Replacement
When replacing the engine control PCB, be careful to ensure that the values entered in data etiting test modes
are not erased.
Values etited by using the "Data Editing" test modes listed in Chapter 17, Section 6, are stored in the memory
of the engine control PCB. For this reason, execute test mode 00415 (store test mode setting values) when
replacing the engine control PCB to send the settings data to the hard disk. After replacement, you must execute
test mode 00416 (restore test mode setting values) to apply the setting values.
