Troubleshooting and Repair Comments
While troubleshooting, if you determine that the reference oscillator crystal (Y201) is defective, the entire Radio Frequency
(RF) board must be replaced. When the new Radio Frequency board is installed, the eight-digit oscillator temperature compen-
sation code, supplied with the new RF board, must be programmed into the radio controller. See the Radio Service Software
(RSS) manual, number 6881086C08 (in English), section 5.3.3. Simply enter the eight-digit code in to the box on the RSS Ref-
erence Oscillator data program using the F8 key on your computer. Keep the new oscillator compensation code in your records.
