Reading off parameters: Notes

NOTE: To obtain the relevant values, the engine must be running and the engine control module (ECM) must be initiated. The engine control module (ECM) is initiated the first time engine speed exceeds 600 RPM.

Certain values may deviate from the values listed in DSA signal description . This is because the values given by VIDA are calculated and filtered by the DSA control module.

No.	TEXT size	Remarks
1	RPM = RPM	Engine Speed (RPM), crankshaft. Measurement range: 0 and up. Idling speed approximately 800 RPM. The DSA control module derives the engine speed (RPM) from the load signal transmitted by the engine control module (ECM). The DSA control module uses the load signal to calculate anti-spin control.
2	LOAD TQ = μs	Load signal from the engine control module (ECM). Measurement range: 0 - 680 μs. Normal range idling with the engine at operating temperature, neutral selected and the air conditioning (A/C) off: approximately 36 μs. The DSA control module uses the load signal to calculate anti-spin control. Value 16 μs indicates when the engine is started. Value 20 μs indicates fuel shut-off in the engine. Value 480 μs indicates that the engine control module (ECM) is being initiated or that there is a fault in the engine control module (ECM). Value 512 μs indicates a fault in the signal from the pressure sensor to the engine control module (ECM).
3	THROT ANG = %	Throttle position (TP) sensor position. Measurement range: 0 - 100 %. Normal value at closed throttle position (CTP): approximately 0 %, wide open throttle (WOT): approximately 100 %. Signal from the engine control module (ECM) about the position of the throttle position (TP) sensor. The DSA control module uses the throttle position (TP) sensor signal to calculate anti-spin control.
4	TO REDUC =	Torque limiting for anti-spin control. 0 = no torque limiting requested. 1 - 16 = torque limiting requested. The DSA control module requests torque limiting from the engine control module (ECM) during anti-spin control. Torque limiting is carried out by shutting off one or more injectors. Torque limiting can be carried out at 16 different levels. Level 1 means that one cylinder is shut off once during four cycles. Level 4 means that the same cylinder is shut off four times during four cycles, i e. all the time. Level 8 means that 2 cylinders are shut off all the time. Finally, level 16 means that all cylinders are shut off all the time.
5	TRANSM = MAN/AUT	Transmission type. MAN = manual transmission. AUT = automatic transmission. The engine control module (ECM) transmits a signal to the DSA control module about the type of transmission. The engine control module (ECM) detects whether there is a signal from the gear-shift position sensor. If there is a signal, the engine control module (ECM) interprets this as an automatic transmission and transmits a signal to the DSA control module. Until the engine control module (ECM) receives a signal from the gear-shift position sensor, the DSA control module interprets it as a manual transmission.
6	INIT ECM = NO/YES	Initiation of the engine control module (ECM). NO = initiation not carried out. YES = initiation carried out. The DSA control module establishes communication with the engine control module (ECM) when the engine speed exceeds 600 RPM for the first time in the ignition cycle. This informs the engine control module (ECM) that there is a DSA system. No anti-spin control van take place until the control module is initiated.
7	DSA FUNC = NO/YES	Activation of the DSA function. NO = The DSA function is disengaged. YES = The DSA function is engaged. When the DSA function is engaged, the system is ready to control. The DSA function can be disengaged with the DSA switch. It will also be disengaged if there is a fault in the DSA system or certain faults in the engine management system.
8	DSA SWITCH = ON/OFF	DSA switch. OFF = The DSA switch is not activated. ON = The DSA switch is activated. The signal from the DSA switch is used to engage / disengage the DSA function.
9	WARN LAMP = ON/OFF	The indicator lamp and DSA warning lamp in the combined instrument panel. OFF = The DSA warning lamp is off. ON = The DSA warning lamp is on. The DSA warning lamp lights when the ignition is switched on, when the DSA function is disengaged manually with the DSA switch or if the DSA control module has detected a fault in the system. If no fault is detected, the DSA warning lamp goes out when the engine speed (RPM) exceeds 600 RPM.
10	W/LAMP FLASH = NO/YES	The indicator lamp and DSA warning lamp in the combined instrument panel. NO = The DSA warning lamp does not flash. YES = The DSA warning lamp flashes. The DSA warning lamp flashes at a frequency of 1.8 Hz during anti-spin control.
11	BRAKES = ON/OFF	Stop (brake) light switch status. OFF = The stop (brake) lamp switch is not activated. ON = the stop (brake) light switch is activated. The signal from the stop (brake) lamp switch is used to prevent wheel adaptation during braking.
12 13 14 15	WS LF = WS RF = WS LR = WS RR = km/h	Wheel speed left front wheel. Wheel speed right front wheel. Wheel speed left rear wheel. Wheel speed right rear wheel. Measurement range: 0 - 256 km/h. The ABS control module transmits signals to the DSA control module about the wheel speeds. The DSA control module uses the wheel speed signals to calculate the wheel speed and anti-spin control.
16 17 18 19	WH AD LF = WH AD RF = WH AD LR = WH AD RR = %	Wheel adaptation, left front wheel. Wheel adaptation, right front wheel. Wheel adaptation, left rear wheel. Wheel adaptation, right rear wheel. Measurement range: 75.00 - 125.00 %. At a constant vehicle speed, the wheel speed varies between the four wheels depending on load, air pressure, wear, tire make etc. The of adaptation is to even out wheel speeds so that DSA control module calculations are based on the same level of wheel speed. At the same speed on all wheels, the adaptation is approximately 100 %. If the speed of one wheel is lower than that of the others (the wheel has a greater circumference), the adaptation will be greater than 100 %. This is to raise the speed level. If the speed of one wheel is higher than that of the others (the wheel has a smaller circumference), the adaptation will be less than 100 %. This is to lower the speed level.
20	WH AD ON = NO/YES	Wheel adaptation permitted. NO = wheel adaptation is not permitted. YES = wheel adaptation is permitted. Wheel adaptation is permitted in normal driving conditions - on a flat road at constant speed and light load in a speed range up to approximately 90 km/h.
