been set to the off position.
Before working on one of these electrical
components, set the master cut-out switch
located above the rear electrical panel to the
off position.
If the vehicle is out of service for a long period
(more than 2 weeks), it is recommended to trip
the main circuit breakers (cb2 and cb6) to
prevent the batteries from discharging.
This will prevent small current drawn by the
mcm memory and the instrument cluster clock
from draining the battery. Note that the
diagnostic codes history will be erased and the
instrument cluster clock will have to be reset.
Setting the cluster clock is performed by the
time/distance menu of the DID. Refer to the
operator’s manual for additional details.
