This bulletin provides information primarily on battery care.
WIS edition 2007-2 will contain this information.
Saab 9-3
If a battery is left without maintenance for long periods, its degree of charge will gradually decrease. The rate at which the degree of charge decreases depends mainly on how much current is being used by the car's electrical system. There is a certain amount of self-discharge even when the battery has been disconnected. This increases with rising temperatures.
If a battery is left with a degree of charge that is too low for a longer period then a chemical process starts where the battery acid is gradually converted into water and the battery plates start to corrode (sulphate). This corrosion process starts to become critical if the battery is left for approx. 2 weeks with a degree of charge below 65-75% (equivalent to an unloaded battery voltage of less than approx. 12.4 volts).
The damage that is then caused is permanent and cannot be remedied with normal battery recharging. As a result, the capacity and service life of the battery will be permanently impaired.
The purpose of this TSB is to prevent this type of damage to the battery arising, and so to enable an increase in the service life of the battery and, above all, to be able to ensure that the customer has a satisfactory battery.
To enable this, the following methods have been changed/added:

Not affected.
Carry out/update handling as per the following instructions.
Underlined text
symbolises links to other instructions found in this bulletin or in WIS. WIS instructions not attached are not affected by this bulletin.
|
1. Pre-delivery inspection
|
Pre-delivery inspection of a new car is mandatory for all Saab cars.
Carry out inspections and confirm with your signature on the
Pre-delivery inspection, form
and Bill of lading.
A new car is to be inspected immediately after reception. The receiver is responsible for ensuring that faults and deviations are reported as described in applicable routines.
|
1.
|
Check that the car's specification matches the order form. This also applies to optional equipment.
|
|
2.
|
Check the underbody for transit damage.
|
|
3.
|
Check that the car's spare wheel/repair kit and tools are present.
|
|
4.
|
Check that
accompanying material
is present.
|
|
5.
|
Carry out
battery check during pre-delivery inspection
.
|
|
6.
|
Clean the car for paintwork and damage inspection. If you clean away dust and dirt with a strongly alkaline cleaning agent, it could affect the paintwork. Keep chemical usage to the bare minimum for this cleaning.
Cars with paint protection plastic:
If there has been damage to the paint protection plastic, remove it to examine the damage. Then store the car, preferably under a roof.
|
|
7.
|
Check the car for damage both inside and out.
|
|
8.
|
Note and report any damage and other observations.
|
Action if the car will be stored
|
1.
|
Check and, if necessary, adjust tyre pressure to 3.5 bar (50 psi).
|
|
2.
|
If the car is stored in an ambient temperature greater than +20°C (69°F), fuel should be filled to min. 2/3 tank. Otherwise, there is a risk of fuel pump malfunction due to oxidation.
|
Additional action if the car is to be stored outdoors
|
1.
|
Check the coolant level and anti-freeze content. The coolant should handle at least -30°C (-22°F). It then also provides maximum corrosion protection. For certain climates, the mixture must handle lower temperatures. Top up as necessary following the specification.
|
|
2.
|
If the car's paint protection plastic has been removed, the car must be stored under a roof.
|
|
3.
|
Drive the car to the parking area. While doing so, brake repeatedly very briefly so that the brake discs become clean and dry.
|
|
|
•
|
The parking brake lever is released to its home position.
|
|

5. Transport mode/customer mode of car's electrical system
|
Because the car's electrical system requires current, there are two different adaptations - transport mode and customer mode.
Transport mode
Minimises the car's current consumption during transport from the factory to the customer. Many customer-oriented functions are then not available, such as central locking of rear doors, rear window lifts and the audio/navigation system. The car is to be removed from this mode only as an exception during the car's handling up until delivery service has been performed. An example of an exception is cars parked in a showroom. If the car is put in customer mode, battery condition must be checked more often.
Function description: Activate transport mode
The front electrical centre sends a signal on the I-bus that the fuse is removed. At the same time, a number of control modules in the rear electrical centre that are powered by this fuse are deactivated. Examples of deactivated functions include the parking assistance system, sunroof and rear door modules.
The Body Control Module (BCM) reads the signal, at which time BCM sends a message on the I-bus indicating that transport mode is activated. This affects the control modules containing customer functions/comfort functions that are not necessary to be able to safely move the car, which is not supplied current by maxi fuse 37 and the rear electrical centre. This operation only occurs during cycling of the ignition to enable distinction from the fuse blowing while driving, at which point other indications/warnings would be given to the driver.
Indication in MIU: "Transport fuse removed".
Activate transport mode
Move the transport fuse from position 37 to TRANSPORT and turn the ignition key to "Ignition ON". Wait until the text "Transport fuse removed" appears in the main instrument unit and then turn the key back to the OFF position and remove it. The car is now in transport mode.
Customer mode
All functions (as per car specification) are now available to the customer.
Note that only the combination of fitting/removing maxi fuse 37 and turning the ignition key to "Ignition ON" changes the mode. So starting and moving the car changes the selected mode if the fuse was removed/inserted (customer or transport mode).
Function description: Activate customer mode
The front electrical centre sends a signal on the I-bus indicating that the fuse is inserted.
The Body Control Module (BCM) reads this signal, at which time the BCM sends a message on the I-bus indicating that customer mode is activated. This only occurs during cycling of the ignition. Thus, the ignition must be switched on and off to activate customer functions (customer mode).

Trickle charging is recommended to prevent battery discharge and damage. The amount of charging should be adapted to current consumption. Too high voltage/current from the charger could damage the battery due to overcharging.
If trickle charging is not possible, the battery must be checked often (depending on current consumption) - a minimum of once a week. Use the standard battery analyser to check battery status.
