| Subject: | Proper Setting of I/P Dimmer
Control To View PRNDL Display with Automatic Headlamp Control |
| Models: | 2000 and Prior All Passenger Cars and Trucks |
| With Automatic Headlamp Control and Electronic PRNDL Display |
Under certain conditions, if the instrument panel dimmer
control is turned relatively low, the PRNDL will not be visible until the
automatic headlamp control turns the headlamps off and the daytime running
lamps (DRL) are turned back on. Such a condition may be if the vehicle is
first started in an environment where the headlamp control turns on the headlamps
and then the vehicle is driven out into a brighter environment
(for example, when a vehicle is backed out of a dark garage into the bright
sunlight).
This condition is normal and any repair attempt will not be successful.
Demonstrate this condition to the customer using the service lane and then
turn the instrument panel dimmer control to a higher setting. This will enable
the driver to see the PRNDL display.
