Dodge Neon / Neon SRT-4. Manual — part 627
second DTC could be set, making diagnosis of the
original problem more difficult.
When replacing a blown fuse, it is important to
use only a fuse having the correct amperage rating.
The use of a fuse with a rating other than indicated
may result in a dangerous electrical system over-
load. If a properly rated fuse continues to blow, it
indicates a problem in the circuit that must be
corrected.

ROAD TEST COMPLAINT VEHICLE
Some complaints will require a test drive as part
of the repair verification procedure. The purpose of
the test drive is to try to duplicate the diagnostic
DTC or symptom condition.
CAUTION: Before road testing a vehicle, be
sure that all components are reassembled.
During the test drive, do not try to read the
DRBIII
T
screen while in motion. Do not hang
the DRBIII
T
from the rear view mirror or
operate
it
yourself.
Have
an
assistant
available to operate the DRBIII
T
.
Road testing is an essential step in the diagnos-
tic process that must not be overlooked. Along with
diagnostic information obtained from the DRBIII
t
Scan Tool and the original customer concern, the
road test helps to verify the problem was current
and any repairs performed, fixed the vehicle cor-
rectly. Always operate and observe the vehicle
under actual driving conditions.
Just as important as the road test is, there are
preliminary inspections that should be performed
prior to the road test. Always check the fluid level
and condition before taking the vehicle on a road
test. Determine if an incorrect fluid type is being
used, improper fluid will result in erratic transmis-
sion operation. Some of the conditions of incorrect
fluid level are as follows:
•
Delayed engagement
•
Poor shifting or erratic shifting
•
Excessive noise
•
Overheating
The next step is to verify that the shifter is
correctly adjusted. If the shifter is incorrectly ad-
justed, a number of complaints can result.
The PCM monitors the Shift Lever Position
(SLP) Sensor continuously. If the shifter is incor-
rectly adjusted, the PCM will sense a shift lever
position that is not correct for the gear chosen by
the driver. This may cause a DTC to be set.
The following complaints may also be the result
of an incorrectly adjusted or worn linkage:
•
Delayed clutch engagement
•
Erratic shifts
•
Vehicle will drive in neutral
•
Engine will not crank in park or neutral
•
Shifter will be able to be moved without the key
in the ignition
•
Not able to remove the ignition key in park
•
Parking pawl will not engage properly
The shifter should also be adjusted when replac-
ing the Transmission, repairing the valve body, or
when repairing any component between the shift
lever and the Transmission.
Some questions to ask yourself when performing
the road test are as follows:
•
Is the complaint or concern what you think the
problem is, based on the driver’s description of
the problem?
•
Is the Transmission operating normally, or is
there a real problem?
•
When does the problem occur?
•
Is the problem only in one gear range?
•
What temperature does the problem occur?
•
Does the vehicle have to sit over night for the
problem to occur?
•
Does the transmission go into Limp-in mode?
4.3.3
ELECTRONIC PINION FACTOR
WARNINGS (IF APPLICABLE)
The pinion factor must be set when replacing the
PCM. Note: The pinion factor is a fixed number
and cannot be changed or updated in some
vehicle applications. If the pinion factor is not set
or incorrectly set, any speed related functions will
not operate correctly i.e. speedometer, speed control,
rolling door locks, and other control modules will be
affected that depend on speed information.

DEFINITIONS
OBDII (EURO STAGE III OBD) Trip - A vehicle
start and drive cycle such that all once per trip
diagnostic monitors have run.
Key Start - A vehicle start and run cycle of at least
20 seconds.
Warm-up Cycle - A vehicle start and run cycle
such that the engine coolant must rise to at least
71°C (160°F) and must rise by at least 4.4°C (40°F)
from initial start up. To count as a warm-up cycle,
no DTC may occur during the cycle.
