DUCATI MONSTER INSTRUMENTAL CLUSTER REPAIR

DIGITEK D04B6R4

Figure 1

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 works:

A. Flash memory program recovery / memory corrupted after welding works /

B. Replacing broken target MCU to the brand new one

C. Setup (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 cluster ( Figure 5 )

3: Restore FLASH memory and setup 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

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 CLUSTER FROM AN EXTERNAL

POWER SUPPLY SOURCE AND B.Y.K.E. PROGRAMMER SIMULTANEOUSLY. OSC1 CONNECTION WIRE MUST BE REMOVED

AFTER MCU PROGRAMMING.

TROUBLES: INSTRUMENTAL CLUSTER DON’T OPERATE PROPERLY AFTER WORKS - MAKE SURE (DOUBLE CHECK

REQUIRED) THAT OSC1 WIRE DISCONNECTED FROM THE TARGET MCU AND PTA, PTC, IRQ, RST SIGNAL LINES

DISCONNECTED FROM ISP INTERFACE ( TURNED OFF ).

Factory settings restored

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.
