02659
From Ross-Tech Wiki
02659 - Power Output Stage for Right Headlight (J668); Incorrectly Coded
Possible Symptoms
- Malfunction Indicator Light (MIL) active
Possible Causes
- Control Module or if Subsystem, Master not coded
Possible Solutions
- Check Control Module Coding
- Cross Reference Control Module Coding with related Control Modules (e.g. for Country or Powertrain Settings)
- Perform Basic Settings (see Special Notes)
Special Notes
- In case an Output Stage is being replaced, the Subsystem/Slave often cannot be coded directly. Instead recode the Headlight Aim Control Module with the proper/current Coding, this will also code the Subsystems/Slaves.
