Idling
IG SW off
2 min
(b) 9 min
(a) 25 mph
(40 km/h)
Preconditions
The monitor will not run unless:

MIL is OFF.
Drive Pattern Procedure
Connect the OBDII Scantool to DLC3 to check monitor status and preconditions.
a. Start the engine and allow it to idle for 9 minutes.
b. Drive the vehicle at 25 mph (40 km/h) or more for at least 2 minutes.
If readiness status does not switch to ªcomplete,º ensure preconditions are met, turn the
ignition OFF, then repeat steps ªaº and ªb.º
NOTE:
The readiness status may not switch to ªcompleteº after the first drive pattern trip if a
Pending Code has been set (first trip for a two±trip DTC).

Pending Codes are available from the DTC Info Menu in Enhanced OBDII.

Pending Codes indicate a POTENTIAL problem was detected. A second trip is
needed to confirm the DTC prior to diagnosis.

Once a second trip is completed, a current DTC will be stored. Readiness

BULLETIN
Apirl 10, 1998

When receiving customer complaints to repair the lighter or lighter socket, please
carefully investigate the cause of the failure to prevent further occurrences. If the
customer uses the wrong size lighter element or power accessory plug, damage may
occur to the lighter socket. When applicable, instruct the customer to replace the lighter
element with original equipment components or to use an appropriate sized accessory
plug. Dimensional information included within this document will instruct you on
component specifications.
1. Determine if the lighter is original equipment by using the specifications shown.
a. If the vehicle has a non±genuine lighter element, it has the possibility to cause
a short circuit between the lighter element and the lighter socket, which can
result in an open fuse.
b. A non±genuine lighter element may cause a rattle or bend the socket bimetal
contacts.
c. If a non±genuine lighter element is being used, advise the customer to use an
original equipment element.
