Enhancement of countermeasures against "E1-00"
communication trouble when turning on the power
communication trouble when turning on the power
1. Model Name
AR-M150/M155,
AL-1556/1566
2. Symptom
When the power of the main unit is turned on, an IMC communication port trouble of
“E1-00” may occur in rare cases.
3. Description
To make enhancement of countermeasures against "E1-00" communication trouble
when turning on the power, the following processes are executed.
(1) One resistor (VRS-CZ1JD103J, location No. R240) attached to the MCU PWB is
removed. (See below.)
(2) A resistor (1k
Ω) is additionally inserted between point A on the MCU PWB side
(GND) of the capacitor (VCKYCZ1CF104Z, location No. C138) attached to the MCU PWB
and point B of 2PIN of location No. CN40. (See below.)
Note: These countermeasures are applied to the MCU PWB’s having "●" mark on the
right upper side of the lower two digits of the parts code, including the MCU PWB's
having old-version parts code.

4. Action
Implementation from January 2007 production: ("●" mark is added to the right upper
side of the lower two digits of the old version parts code of the MCU PWB.)
Implementation from February 2008 production: (The pars code of the MCU PWB will
be changed. )
