The TCM detects uphill driving by comparing the
engine load transmitted by the PCM with the engine
speed. If the engine load increases and the engine
speed falls, then the TCM causes the transaxle to
shift to a lower transmission range in order to
increase the traction force.
Downhill driving
The TCM detects downhill driving by comparing
the engine load and engine speed values
transmitted by the PCM with the OSS sensor
signal. In order to prevent overloading of the
vehicle brakes, the TCM causes the transaxle to
shift to a lower transmission range.
Hill-hold function
If the vehicle is stopped on an uphill incline, the
TCM detects this through the faster drop in engine
speed compared with the drop in engine speed
when stopping on the flat. In this situation, the
hydraulics are actuated by the TCM in such a way
that the vehicle is prevented from rolling back. This
function is not used on steep inclines.
If the vehicle is parked on an uphill incline (ignition
switched off), the hill-hold function is not active
when pulling away.
Altitude correction
Lower air density results in reduced engine
performance. In order to compensate for this
operating situation, the TCM changes the shift
points.
Selector lever lock
To prevent the selector lever being accidentally
moved from the P or N position, the vehicle also
has an electrically operated selector lever lock.
This blocks the locking pin in the locking segment
and thus locks the selector lever in the P or N
position.
Shifting from P into another transmission
range
To be able to move the selector lever from P into
another transmission range, the ignition must be
switched on and the brake pedal must be
depressed (stop light switch on). The TCM detects
the position of the brake pedal via the CAN data
bus and the engaged transmission range from the
TR sensor.
The signal is then transferred from the TCM to the
select-shift switch module in order to activate the
solenoid valve in the selector mechanism
assembly.
In position P, the solenoid valve is activated and
the locking pin is pulled in so that the lock button
on the selector lever can be pressed as usual to
engage another transmission range.
In the selector mechanism assembly there is a Hall
sensor which is affected by a permanent magnet
on the gate of the selector mechanism assembly.
If the selector lever is moved from the P position,
both the Hall sensor and the selector lever lock
solenoid are simultaneously deactivated, to prevent
the selector from being kept in the N position.
If the ignition is set to "I" or "0" the solenoid valve
is deactivated. When the selector lever is in the P
position, it is mechanically locked because it has
no voltage.
Shifting from N into another transmission
range
The conditions are the same as for shifting from P
into another transmission range.
However, the lock button on the selector lever must
be pressed to be able to select R or P.

Principles of Operation
WARNINGS:
This procedure involves fuel additive
handling. Be prepared for fuel additive
spillage at all times and always observe
fuel handling precautions. Failure to follow
these instructions may result in personal
injury.
Eye, hand, ear protection and protective
clothing are required to be worn during
any general service or removal and
installation service procedure of fuel
additive system components. Failure to
follow this instruction may result in
personal injury.
In case of fuel additive fluid contact with
the skin or the eyes, flush immediately with
water for a minimum of 15 minutes and
seek prompt medical attention. Failure to
follow these instructions may result in
personal injury.
If fuel additive fluid is swallowed, call a
physician immediately. Rinse mouth
immediately with water, do not induce
vomiting. Failure to follow these
instructions may result in personal injury.
Always provide adequate ventilation when
working on the fuel additive fluid system
or related components. Failure to follow
these instructions may result in personal
injury.
Do not smoke or carry lighted tobacco or
open flame of any type when working on
or near any fuel related components.
Highly flammable vapors are always
present and may ignite. Failure to follow
these instructions may result in personal
injury.
CAUTION: Make sure the workshop area
in which the vehicle is being worked on is
as clean and as dust free as possible.
Foreign matter from working on clutches,
brakes or from machining or welding
operations can contaminate the fuel
system and may result in later malfunction. The fuel additive system is an on-board system
that allows the injection of an additive at each
refueling operation by the customer. The additive
quantity is proportional to the fuel quantity that has
been added. The fuel additive system module
controls the amount of additive fluid entering the
fuel tank at each refueling, A switch mounted on
the fuel filler flap is used to detect the start of the
refueling event and the fuel gauge that is mounted
within the fuel tank informs the fuel additive tank
module the quantity of actual fuel added.
Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of leakage
and mechanical or electrical damage.
