Hello, My Failsafe mode comes on shortly after driving a few miles. I realized that my taillights come on without turning on the lights not brake lights but taillights. Has this happen to anyone? Its a 2000 VDP
Thanks Garry

 

I can’t help you on the failsafe mode but the following (from wrair in another thread) describes the daytime running lights operations in different markets. My XJR operates the same way you describe your VDP but it is a Canadian car still in Canada. I think it might be possible to toggle between the various defaults but there’s nothing wrong with how it’s operating now:

From the workshop manual:

Daytime Running Lamps (DRL) - Daytime Running Lamps (DRL) Description and Operation

INTRODUCTION
Daytime Running Lamps (DRL) use the full intensity low beam headlamps which are permanently illuminated when the vehicle is being driven. DRL are used in a number of markets and there are two systems to cover these markets.
For additional information, refer to: Exterior Lighting (417-01 Exterior Lighting, Description and Operation).

DRL CANADIAN MARKET
DRL for this market use full intensity low beam headlamps. The side marker lamps, tail lamps and license plate lamps will be on, but instrument cluster illumination will be off. DRL are active when the following parameters are met:
 PARK is not selected on automatic transmission selector lever  Power mode 6 (ignition on) detected by the auxiliary junction box  The Central Junction Box (CJB) receives an engine running signal  The lighting control switch is in the off or side lamps position.
NOTE: If the lighting control switch is moved to the headlamp position, DRL are deactivated and normal side lamp and headlamp functionality is operational.
NOTE: Adaptive Front lighting System (AFS) (where fitted) is non-functional when the DRL are active.
NOTE: When DRL are active, the headlamp flash function using the left hand steering column multifunction switch will operate normally.
The high beam headlamp function using the left hand steering column stalk switch will be deactivated. When the selector lever is in the PARK position on automatic transmission vehicles, DRL are turned off. This is to reduce battery discharge during long periods of engine idling in cold climate conditions. When the selector lever is moved from the PARK position, normal DRL functionality is restored.

DRL DENMARK, HOLLAND, NORWAY, SWEDEN, FINLAND AND POLAND
DRL for these markets use full intensity low beam headlamps. Side lamps and license plate lamps will be on, but instrument cluster illumination will be off. DRL are active when the following parameters are met:
 Power mode 6 (ignition on) detected by the auxiliary junction box  The CJB receives an engine running signal  The lighting control switch is in the off position.
NOTE: When DRL are active, the headlamp flash function using the left hand steering column multifunction switch will operate normally. The high beam headlamp function using the left hand steering column stalk switch will be deactivated.
If the lighting control switch is moved to the side lamp or headlamp positions, DRL are deactivated and normal side lamp and headlamp functionality is operational.
The DRL (daytime running lamps) and side lamps are incorporated into the outer part of the headlamp assemblies. For additional information, refer to: Exterior Lighting (417-01 Exterior Lighting, Description and Operation).
The same LED (light emitting diodes) are used for the two lamp functions, but they illuminate with a higher intensity for DRL operation than for side lamp operation. On Japan vehicles, the DRL function is inoperative.
