Electrical System
As of model year 1990, Wiesbaden and Delta radios are assigned a fixed four digit security code from the factory. Unlike previous coded radios, the security code cannot be changed.
The fixed coded radios have been implemented gradually and can be identified by the part number. A part number label is attached to the radio chassis.
Wiesbaden - Part No. 893 035 180A
Delta - Part No. 893 035 093B
Delta Bose - Part No. 893 035 093C
CAUTION
Part numbers are for reference only. Always check with your Parts Department for latest information.
The radios are not coded at the factory. To activate the theft protection, the radio must be coded during the Pre-Delivery Inspection.
The security code and serial number of the radio are printed on a removable sticker located in the trunk near the vehicle identification sticker.
Coding a new or remanufactured radio
^ remove radio security code/serial number sticker from trunk and attach to radio card in operating instructions manual
CAUTION
DO NOT keep the security code or radio card with the vehicle. Always instruct customers to detach radio card from operating instructions manual and keep in a safe place.
Note
The security code/serial number sticker for remanufactured replacement radios comes in the box with the new radio. Place the new sticker over the old sticker on the radio card.
^ switch radio ON
^ radio plays and radio station frequency is displayed
Note
To activate the coding procedure, use the AM/FM and SCAN buttons on the Wiesbaden radio and the AM and ARI-Z buttons on the Delta radio.
Delta radio buttons are indicated in parentheses.
^ push and hold AM/FM (AM) and SCAN (ARI-Z) buttons
^ radio display changes to CODE and then 1000
^ release AM/FM (AM) and SCAN (ARI-Z) buttons
^ 1000 will remain on display
Note
If the AM/FM (AM) and SCAN (ARI-Z) buttons are held down too long or pushed again, the radio will misinterpret the 1000 as an attempt at coding and one incorrect attempt will be logged.
^ enter radio's security code using program station buttons (use first four buttons on Wiesbaden radio)
^ security code will appear on display
^ push and hold AM/FM (AM) and SCAN (ARI-Z) buttons once again until display changes to SAFE
Note
Each fixed coded radio will only accept its factory assigned security code.
^ release AM/FM (AM) and SCAN (ARI-Z) buttons radio display changes to a radio station frequency radio is now coded
Reactivating radio after reconnecting power
After disconnecting power (fuse, battery, etc.) to the radio, the radio will lock up electronically.
To reactivate:
^ obtain radio's security code
^ located on radio card
^ switch radio ON
^ radio will not play
^ radio display shows SAFE
^ push and hold AM/FM (AM) and SCAN (ARI-Z) buttons
^ display changes to 1000
^ release AM/FM (AM) and SCAN (ARI-Z) buttons
^ 1000 remains on display
Note
If the AM/FM (AM) and SCAN (ARI-Z) buttons are held down too long or pushed again, the radio will misinterpret the 1000 as an attempt at coding and one incorrect attempt will be logged.
^ enter radio's security code using program station buttons (use first four buttons on Wiesbaden radio)
^ security code will appear on display
^ push and hold AM/FM (AM) and SCAN (ARI-Z) buttons once again until display changes to SAFE
^ release AM/FM (AM) and SCAN (ARI-Z) buttons
^ radio display changes to a radio station frequency
^ radio is now coded and plays
Unlocking an electronically locked radio
After two incorrect attempts at entering the security code, the radio will lock-up electronically. The display shows SAFE and will not change.
To unlock:
^ leave radio switched ON for approximately one hour
^ after one hour, reactivate (code) radio as it would be after a power interruption
Note
The radio will never permanently lock-up no matter how many incorrect coding attempts are made. The reactivation procedure can be repeated indefinitely.
See Warranty Service Circular 89-22-A, dated September 30. 1989 for instructions on obtaining a lost or forgotten security code.
