General
DICE is a comprehensive control system for the electronic functions in the car. The central unit in DICE is a control module which communicates with the system units and with other systems via the car's wiring and the instrument BUS (I-BUS). DICE has its own diagnostics function and diagnostic trouble codes are set when faults arise.
The following functions are controlled by DICE
- Exterior lighting
- Interior lighting
- Rheostat control
- Acoustic warning
- Intermittent wiper, windscreen
- Intermittent wiper operation, rear window (5D)
- High-pressure cleaning, headlamps
- Electrically heated rear window and door mirrors
- Radiator fan
- Air conditioning
Exterior lighting
The car's exterior lighting is operated with the headlamp switch and the left-hand toggle switch combined with the DICE control module.
The following light functions in the car's exterior lighting system are controlled by DICE
- Headlamps
- Front fog lights
- Rear fog lights
- Direction indicators
- Hazard warning lights
Interior lighting system
General interior lighting (dome lamps) in the car. Automatic or manual function depending on the position of the light switch.
The following light functions in the interior lighting system are controlled by DICE
- Cabin lighting
- Map Light
- Vanity mirror lighting
- Glove box light
- Floor light
- Courtesy lights
- Luggage compartment lighting
DICE supplies power to the button and control lighting. The light intensity is controlled by DICE using pulse width modulation (PWM) of the supply voltage to the lamps.
If the Night Panel function of SID has been selected, the bulbs in the button and control lighting will shine with reduced strength.
Acoustic warning
Acoustic warning if the driver's door is opened while the key is still in the ignition.
Acoustic warning if the parking lights are on and the driver's door is opened while the key is not in the ignition.
The function is programmable.
Windscreen and rear window wiping, intermittent
When using the intermittent function on the windscreen wipers, the time between the strokes can be varied from 2 to 15 seconds and is adjusted using a potentiometer located on the control lever of the wiper switch.
DICE also controls the wiper function for windscreen and rear window washing (5D). For a short wash, the wiper arms swipe three times. For a longer wash, the wiper strokes increase to a maximum of five strokes. The rear window wiper swipes a few strokes after a slight delay when washing.
The "extra wiper stroke" function after washing" is programmable.
High-pressure cleaning, headlamps
DICE activates the relay for headlamp washing. The maximum wash time for the headlamps is 150 seconds when washing the windscreen.
Electrically heated rear window and door mirrors
Electric heating of the rear window and exterior rear-view mirrors. These functions are activated manually or automatically via the car's ACC function, alternatively manually when the car has MCC.
Radiator and battery fans
DICE controls when the radiator fan is switched on and off. Depending on the market, the car is equipped with either 1 or 2 radiator fans and 1 battery fan. The battery fan starts when the car's radiator fan starts at low speed.
On cars without A/C, one fan. DICE switches the radiator fan on/off.
On cars with A/C, 2 fans. DICE controls whether one or two fans will be used.
DICE uses the following information to control the function
- Coolant temperature
- A/C pressure
- Outside temperature
- Vehicle speed
Air conditioning
Control of the A/C function. DICE uses the following values to determine whether the A/C compressor should be allowed to operate
- Coolant temperature
- A/C system working pressure
- Evaporator temperature (up to VIN 33017341)
- Outside temperature
- Vehicle speed
- Time that the engine has been running
If DICE gives approval for the A/C compressor to operate, DICE sends a BUS message that is used by the engine control system to activate the compressor clutch relay.

Scope
Nominal values and instructions for measuring voltages on the control module can be found under the respective headings below.
Scheme 70
- Note the test conditions and use common sense when assessing the test result.
- The nominal test readings shown apply with the ignition switched ON unless otherwise stated.
- First check that the control module has a power supply and is grounded.
- Then check all sensor inputs and signals from other systems.
- Finally, check the outputs. Remember that the test readings do not tell us whether or not the module is functioning properly.
- If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which should be checked more thoroughly.
- The specified test readings refer to those obtained with a calibrated Fluke 88/97.
- Test readings % (+) and ms (+) show the pulse ratio and pulse duration of the signal. The test instrument used must be able to measure pulse ratio and pulse width. The (+) sign denotes a positive trigger pulse, TRIG+.

- The customer's description of the problem constitutes a basis for the fault diagnosis strategy. If necessary, the customer must demonstrate the trouble on the car to avoid misunderstandings.
- In certain cases, the function may be correct. 2.a. Good product knowledge is required to decide this. 2.b. If the function is correct, this must be explained to the customer.
- If the function is judged to be faulty, the car should be repaired. Saab's fault diagnosis strategy assumes that the technician is familiar with the customer's description of the problem. So note the customer's complaint and any other observations on the job sheet.
- The technician obtains a readout of the diagnostic trouble codes from all systems. A malfunction in one system can often be caused by a fault in another system.
- The car may contain diagnostic trouble codes which are secondary faults or which have been incorrectly generated. 5.a. Compare the customer complaint with the symptom description for the various diagnostic trouble codes. WIS has a quick search function for this purpose. 5.b. If the symptom description for a diagnostic trouble code matches the customer's complaint, this diagnostic trouble code is probably caused by the primary fault. Repair as per instructions.
- If there is no match with diagnostic trouble codes or symptoms, the technician must diagnose the fault himself. 6.a. Search in WIS under fault diagnosis for symptoms in the system where the fault exists. Also check whether there is a TSB/MI in force. 6.b. If the symptom description in the current system matches the complaint, the right fault diagnosis description has probably been found. Repair as per instructions.
- Certain fault symptoms can be remedied by reprogramming the control module. 7.a. Does the customer complaint stem from a known software problem in a programmable control module? 7.b. Reprogram the control module following the instructions in SPS.
- If there is no match with diagnostic trouble codes or symptoms, the technician must diagnose the fault himself. Good technical product knowledge is required to solve this type of problem.
- A final check must be carried out after the repair.
- The car is ready.
Control module
When the control module is supplied with current, the processor in it is tripped. The processor then reads the instructions stored in the control module's memory.
The control module is programmed to read the inputs and activate the outputs. If the control module program is faulty, the diagnostic trouble code "Internal Control Module Fault" will be generated.
The control module must be supplied with current before the system will function. The control module is supplied with current and the processor tripped when the control module can be contacted by the diagnostics instrument.
Outputs
The purpose of the system is to control a number of functions by means of various actuators, such as an injector or lamp. For the system to be capable of performing its functions, it must be possible to activate the actuators. For this reason the actuators must be connected to the control module and have a proper power supply or ground connection.
The performance of the majority of the actuators can be checked with the diagnostics instrument.
Inputs
A condition for the control module's capability of controlling its actuators is that the system's sensors supply it with correct values.
Sensor performance can be checked with the diagnostics instrument.

It is our experience that the majority of control modules returned to us for repair or replacement under warranty are in perfect working order. In these cases, fitting a new control module has obviously not cured the fault. Therefore, go through all the following points carefully before changing the control module
Scheme 81
- Check the latest edition of TIS2000 to see whether the problem can be solved with a control module software update (for control modules that can be reprogrammed). IMPORTANT: Avoid SPS programming unless it is absolutely necessary. It is extremely important to follow the instructions for SPS programming to avoid damaging the control module.
- Check all grounding points and the power supply to the control module.
- Check with a diagnostic tool that all the readings are plausible (several readings can affect one function).
- Check with the diagnostics tool that all activations function normally. (Malfunction in one output circuit can affect another output circuit).
- If the fault persists, the control module must be changed. Fill in the "Checklist for changing turbocharger and engine control module" before changing the control module and attach it when the control module is returned.
- Control modules are sensitive to electrostatic discharges. Great care must be taken to follow the following procedure to avoid damaging internal components in the control module: Keep the control module in its packaging for as long as possible. Never touch the pins of a control module with your hands or clothing. Ground yourself by touching part of the car's body/engine. Unplug the connector from the car's control module. Place the exchanged control module in its return packaging without touching the pins. Ground yourself by touching part of the car's body/engine. Plug in the connector to the car's control module.
Scheme 82
A suitable instrument to use is a multimeter.
The ohmmeter must not be used to test components containing semi-conductors, e.g. control modules and relay with timing functions, etc.
When measuring resistance, the power supply to the system being tested must be disconnected as the measuring instrument generates a weak current in the circuit in question.
This is done to ensure that there is no current already in the tested circuit and that the correct reading is obtained.
Scheme 83
Scheme 84
- Turn on the load.
- Set the multimeter for measuring voltage and connect the negative lead of the voltmeter to a good grounding point.
- Connect the positive lead of the voltmeter to the point where the voltage is to be read.
- On the output side of switches/control modules, it is better to start checking from these and gradually work your way towards the load. When there is no longer a voltage reading, you will have gone past the break point.
- On the input side of switches/control modules/consumers, it is better to start at the power source (normally a fuse) and then move gradually towards the switch/control module/consumer. When there is no longer a voltage reading, you will have gone past the break point.
Scheme 85
Scheme 86
- Make sure the component or lead to be tested is not under tension (e.g. by removing the relevant fuse).
- Set the multimeter for measuring ohms and connect the ohmmeter to each end of the component/lead to be tested.
- Jiggle the relevant wiring harness while observing the ohmmeter. Normally, the resistance of a wiring harness is less than 1 ohm. Specified values apply to components.
Scheme 87
Scheme 88
- Make sure the lead being tested is not under tension (e.g. remove the relevant fuse) and that any loads are disconnected.
- Set the multimeter for measuring ohms.
- Connect one test lead to a good ground and the other to the point to be tested.
- Carefully jiggle the wiring harness and make sure the multimeter reading shows infinite resistance (OL) all the time.

- When detaching connectors with locks, it is essential that the lock is released before the connector is detached. Ensure the connector locks properly when connecting. Example of some different connector types used in the car: 1.A. Pull out the slide to unlock the connector. After attaching the connector lock it by pressing in the slide. NOTE: Using a small screwdriver will help to unlock the connector. 1.B. Press in the lock tab to unlock the connector. Make sure the connector is locked properly when connecting. 1.C. Pull out the slide to unlock the connector. After attaching the connector lock it by pressing in the slide. 1.D. Press in the brace catch and push forward the brace. Push back the brace to lock the connector after connecting. NOTE: Make sure the brace is locked in the right position to ensure good contact between connectors. 1.E. Lift up the lock tab to unlock the connector. Make sure the connector is locked properly when connecting. 1.F. Press in the connector lock tab to release the brace. Release the connector slide while pushing the brace forward. NOTE: The connector may be damaged if too much force is used to push forward the brace without first releasing the slide. Push back the brace to lock the connector after connecting.
- Ground yourself by touching the car body/engine before removing or fitting any of the connectors on the car's control modules.
- Never pull the wiring harness when removing a connector.
- Never touch the pins on the control module with your hands or clothes. IMPORTANT: Incorrect handing or the use of the wrong tool can damage the sleeves in the connector. Use a test cable (part no. 86 12 731) of the correct size to avoid damaging the sleeves in the connector.
- When testing only probe tips intended for the purpose are to be used to avoid damaging the contacts. Use a test cable (part no. 86 12 731) of the right size.
- Connectors may only be repaired when using specified special tools and spare parts.
- The following connectors must not be repaired: Screened wires/coaxial cables (e.g. ESP sensor cable) Airbag system and pyrotechnical seat-belt tensioner system High tension cable (e.g. ignition system, xenon lamp).
Scheme 97
Scheme 98
- Check for any contact problems in connections.
- Check contacts, connectors and crimp connections with respect to oxidation, loose pins and pin clamping force. IMPORTANT: Incorrect handing or the use of the wrong tool can damage the sleeves in the connector. Use a test cable (part no. 86 12 731) of the correct size to avoid damaging the sleeves in the connector.
- To check the connector clamping force, use a test cable with the right pin size (from kit 86 12 731). NOTE: Using a test cable that is too big will damage connector sleeves. Insert the test cable pin into the connector pin to feel the clamping force of the pins in question. Poor clamping force of the connector pins can cause bad contact. Also check that the engagement height of the pin is the same as the other pins in the connector. An engagement height that is too low could be an indication of a loose pin in the connector, which could cause bad contact.
- Check wires and connections for open circuits.
- Check wiring harness, connectors and ground connections.
