S2R/S4R functional instrument panel designed as compact analog-digital unit and it is operate as a real

on-board computer. S4R instrumental panel shown on Figure 1. S2R800-100 you’ll see on Figure 2.
It’s two identical instrumental panels with built-in main MC908LJ24 /CFQF-0L83S/ 80QFP microcontroller.

Typical troubles:
A. Recovery memory program totally erased after welding works
B. Replacing broken target MCU to the new one
C. Set (restore) original or zero mileage after repair works
Troubleshooting: Restore FLASH memory with B.Y.K.E programmer re-program procedure (ISP access to the MC68HC908LJ24)
1: Connect power supply wires for check procedure /turn OFF external power supply source/ (Figure 4)
2: Connect programmer board to the target instrumental panel (Figure 5)
3: Restore FLASH memory and set ODO to ‘0 km’ (Figure 9)
4 : Restore original mileage by under-winding method and set ODO to ‘15905 km’ (Figure 1)
5 : Disconnect ISP MON08 interface
6 : Turn ON external power supply source than check displays messages
Note:
The mask set is identified by a 5-character code consisting of a version number,
a letter, two numerical digits, and a letter, for example 0L83S.
All standard devices are marked with a mask set number and a date code.
FLASH memory consists of an array of 24,576 bytes for user memory plus a
block of 48 bytes for user interrupt vectors. An erased bit reads as logic 1 and
a programmed bit reads as a logic 0. The FLASH memory page size is defined as
128 bytes, and is the minimum size that can be erased in a page erase operation.
Program and erase operations are facilitated through control bits in FLASH
control register (FLCR). The address ranges for the FLASH memory are:
• $9000–$EFFF; user memory, 24,576 bytes
• $FFD0–$FFFF; user interrupt vectors, 48 bytes

Note: DON’T TURN ON TARGET POWER SUPPLY TO THE TARGET INSTRUMENTAL PANEL FROM AN EXTERNAL POWER
SUPPLY SOURCE AND B.Y.K.E. PROGRAMMER SIMULTANEOUSLY. OSC1 CONNECTION WIRE MUST BE REMOVED
AFTER MCU PROGRAMMING.
TROUBLES: PANEL DON’T OPERATE PROPERLY AFTER WORKS - MAKE SURE (DOUBLE CHECK REQUIRED) THAT
OSC1 WIRE DISCONNECTED FROM THE TARGET MCU AND PTA, PTC, IRQ, RST PINS DISCONNECTED FROM ISP
INTERFACE (TURNED OFF).

Note: An internal FLASH memory (EEPROM properties emulation) is used to store odometer and data.
Internal page 128 Bytes used “2-byte data array method”, it’s provides 60 times programming before the an erase is required.
Warning:
If the FLASH memory data is incorrect (check sum error) you should see on display error messages. To restore normal operate
write correct data into the FLASH memory.
