Parameter Read Off, ECC

WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Certain values can differ from values in Signal specification ECC , which is because the values as follows are often calculated and filtered by the control module. In addition in certain cases the control module displays substitute values when a diagnostic trouble code (DTC).

NOTE: With the air distribution selector in the AUTO position the control module controls some functions, which can be seen by checking certain parameters. For this reason do not use the AUTO position, select another position.

No.	TEXT Units of measurement	Remarks
1	D+= OFF/ON	Generator (GEN) voltage D+, status OFF = Generator not charging ON = Generator charging
2	FAN SELECT= AUTO/0/ON/MAX	Blower fan switch, position AUTO= AUTO selected 0 = Position 0 selected ON = Fan on MAX = Fan at maximum speed
3	SELECT= DEFR/FL-DEFR/FLOOR/BI-LEVEL/VENT/AUTO	Air distribution selector, position Several positions on the selector can have the same description
4	LTEMP KNOB= MAX/27-17°C (80.6-62.6°F)/MIN/ERR	Left temperature selector, position ERR= Shows there is a fault on the passenger compartment temperature selector signal.
5	RTEMP KNOB= MAX/27-17°C (80.6-62.6°F)/MIN/ERR	Right temperature selector, position ERR= Shows there is a fault on the passenger compartment temperature selector signal.
6	REC= OFF/ON/NOT ACT	Recirculation switches, status OFF= REC-OFF depressed ON= REC-ON depressed NOT ACT= No buttons depressed
7	AC= OFF/ON/NOT ACT	Damper Motor Position Sensor recirculation, position OFF= A/C-OFF pressed in ON=A/C-ON pressed in NOT ACT= No buttons depressed
8	REC SHUTT= %	Damper Motor Position Sensor air distribution, position Measurement range: 0-100% 0%= DEF position 100%= FLOOR position The blower fan must be operating, or the engine must be idling in order for the control module to active the damper motor when the selector is turned.
9	MODE SHUTT= %	Voltage generator (GEN) D+, status Measurement range: 0-200% 0%= Position DEF 100%= Position FLOOR 200%= Position VENT VLJ= The blower fan must be operating, or the engine must be idling in order for the control module to active the damper motor when the selector is turned.
10	DTEMP SHUTT= %	Position sensor temperature damper motor driver, position Measurement range: 0-100% 0%= Minimum temperature 100%= Maximum temperature The blower fan must be operating, or the engine must be idling in order for the control module to active the damper motor when the selector is turned.
11	PTEMP SHUTT= %	Position sensor temperature damper motor passenger, position Measurement range: 0-100% 0%= Minimum temperature 100%= Maximum temperature The blower fan must be operating, or the engine must be idling in order for the control module to active the damper motor when the selector is turned.
12	SUN INTEN= W/m2	Sun intensity, value Sun intensity calculated on the basis of the solar sensor signal.
13	CAB TEMP= °C (°F)	Passenger compartment temperature, value Temperature based on passenger compartment temperature sensor signal.
14	ECT= °C (°F)	Engine coolant temperature (ECT) The control module derives temperature from engine control module's (ECM) signal.
15	AMB.TEMP= =°C (°F)	Outside temperature, value Derived temperature based on signal from outside temperature sensor signal.
16	TID= XXHXXM	Time since ignition ON. Shows hours and minutes.
17	SPEED= km/h (mph)	Vehicle speed, value Calculated speed based on signal from combined instrument panel
18	CAB TEMP FAN= OFF/ON	Fan passenger compartment temperature sensor, status OFF= Fan off ON= Fan on The fan is mounted in the passenger compartment temperature sensor.
19	FAN UNIT= OK/NOT OK/ERR	Communication with blower fan power unit, status OK= Communication OK NOT OK= Communication not OK, a diagnostic trouble code (DTC) may be stored ERR= The blower fan control module has registered a fault in the fan and a diagnostic trouble code (DTC) may be stored.
20	BLOWER= %	Control module control of blower fan, value Measurement range 0 - 100%. The value indicates how much the control module wishes the fan to be activated, the signal goes to the power module which regulates the blower fan motor to the control module requirements. The higher the value the higher the speed required by the control module.
