When using the menu via the steering wheel buttons (3/131) information is transmitted from the steering wheel module (SWM) (3/254) to the infotainment control module (ICM) via the CAN network. The information is then transmitted to the phone module (PHM) via the MOST network.
Menu management is displayed for the user in the display for the infotainment control module (ICM). Information is transmitted from the phone module (PHM) to the infotainment control module (ICM) via the MOST network.
When starting the phone module (PHM), receiving incoming calls or when using the phone, a request to use the display will be transmitted to the infotainment control module (ICM).
Phone calls can be connected via handsfree or the handset. Unlike the S80, S60 and V70 the phone module (PHM) for the XC90 does not have a separate microphone or loudspeaker for handsfree.
For calls via handsfree the microphone and loudspeaker connected to the audio module (AUD) (16/105) are used. The phone module (PHM) transmits a request to the infotainment control module (ICM) to get access to the microphone and loudspeaker that are connected to the audio module (AUD).

Volvo On Call

Model year -2006





Model year 2007-




Volvo On Call is a system developed by Volvo where the owner has access to different services for safety and service. The service is based on the passenger or driver being able to contact a Volvo On Call Service Center by phone. The personnel at the service center, decide what action to take, depending on the circumstances. Using the information from the On Call system, including the exact position of the vehicle, the service center can quickly direct ambulance, police and recovery vehicles to the vehicle. The different services provided can be separated into two groups, service and safety.

A Volvo On Call service can be activated in one of the following ways:
- by the customer via the switches for Volvo On Call (3/267)
- by the Volvo On Call Service Center
- by the vehicle system.
The strength of the lighting in the switches for Volvo On Call is controlled via the rheostat controls in the light switch module (LSM) (3/111).
Phone module (PHM) (16/60) receives the rheostat signal from the central electronic module (CEM) (4/56) via infotainment control module (ICM) (16/94) on the MOST network.
When activating a Volvo On Call service the phone module (PHM) transmits the information to the infotainment control module (ICM). The infotainment control module (ICM) transmits on to the driver information module (DIM) (5/1) that displays a text message that a Volvo On Call service is activated and what status it has.
Each time a Volvo On Call service is started the present vehicle data is transmitted to Volvo On Call Service Center. The vehicle data contains information about:
- Call type. SOS or On Call service.
- The time at which the message was transmitted. The Phone module (PHM) receives information about time from the Aerial module (ATM) (16/110) (-2006) or the Multimedia module (MMM) (16/108) (2007-), via the MOST network.
- The Vehicle VIN number. Phone Module (PHM) receives information from the central electronic module (CEM) via the controller area network (CAN).
- Alarm status (deactivated, activated, deployed). The phone module (PHM) receives information about the status of the alarm from the central electronic module (CEM) via the controller area network (CAN).
- Position of the ignition key. The Phone module (PHM) receives information about the position of the ignition key (in/out, position I, II or III) from the central electronic module (CEM) via the controller area network (CAN).
- The vehicle's position. The Phone module (PHM) receives the position of the vehicle, from the Aerial module (ATM) (-2006) or the Multimedia module (MMM) (2007-), via the MOST network.
- Voltage source. What voltage source is used by the phone module (PHM). Main or back-up battery.
- Engine running or not. The phone module (PHM) receives a signal from the central electronic module (CEM) via the controller area network (CAN).
- Fuel volume. The phone module (PHM) receives the information about the remaining fuel volume from the central electronic module (CEM) via the controller area network (CAN).
- Status of main battery. The phone module (PHM) receives information about the voltage over the main battery from the central electronic module (CEM) via the controller area network (CAN).
- Ambient and internal temperature. The phone module (PHM) receive information about the ambient temperature from the central electronic control module (CEM) and the internal temperature from the climate control module (CCM) (3/112) via the controller area network (CAN).
- Locked/unlocked. The phone module (PHM) receives information about whether the vehicle is locked from the inside or from the outside, from the Central electronic module (CEM) via the controller area network (CAN).
- Front side window open/closed. The phone module (PHM) receives information about the status of the front side windows from the driver door module (DDM) (3/126) and the passenger door module (PDM) (3/127) via the controller area network (CAN).
- SRS activated or not. The phone module (PHM) receives information about whether the vehicle has been in a collision and the SRS system has been activated. The information is received from the Supplemental restraint system module (SRS) (4/9), both via the controller area network (CAN) and the collision cable. The collision cable runs from the Supplemental restraint system module (SRS) to the phone module (PHM) and the central electronic module (CEM). The collision cable is a backup solution in the event of the controller area network (CAN) communication disappearing.

Safety
An SOS service can be started in two ways:
- automatically, in the event of a collision when a component in the SRS system has been activated
- manually, by the customer pressing the SOS button or selecting the service from the phone menu.
In a collision where an SRS component is activated the signal is transmitted from the supplemental restraint system module (SRS) to the phone module (PHM). The phone module (PHM) transmits the vehicle data to Volvo On Call Service Center which connects a call to the vehicle. The call is made in order to establish what action is necessary, for example, whether an ambulance or recovery vehicle is required.
When a Volvo On Call service has been activated the reserve battery is used if there is not sufficient voltage in the main battery.

Service
Via the ON CALL button the customer can access various service functions, such as:
- roadside assistance, for example help with a puncture or fuel stoppage
- remote unlocking of the vehicle
- tracking the vehicle, can be carried out at the customer's request if the vehicle has been stolen
- informing the owner that the alarm has deployed.
The services that the customer can access vary between different markets.
Remote unlocking of the vehicle occurs after the owner has contacted the Volvo On Call Service Center, identified themselves using a password and given the required service. The owner and Volvo On Call Service Center then decide at what time the vehicle should be unlocked. The Service center can then transmit a command to the phone module (PHM) that the vehicle must be unlocked.
The phone module (PHM) then transmits a request via the controller area network (CAN) to the central electronic module (CEM) that the vehicle must be unlocked at a particular time. The phone module (PHM) then transmits an acknowledgement to Volvo On Call Service Center that the vehicle is unlocked. When one of the doors or the tailgate is opened the alarm will be deployed. The alarm remains active until it is shut off correctly.
If the vehicle alarm is activated, for example by theft, information about the alarm status is transmitted from the central electronic module (CEM) to the phone module (PHM) via controller area network (CAN). If the alarm is active for more than 15 seconds the phone module (PHM) transmits the vehicle data to the Volvo On Call Service Center, which contacts the owner and informs what has happened. In the first instance Volvo On Call Service Center calls the vehicle, if the person answering cannot give the password the owner is called on other numbers that that the owner has supplied to the Service center.
If the vehicle has been stolen the owner can request that the service center tracks the vehicle. The Service center transmits a request to the phone module (PHM) to continuously send vehicle data. The interval of the vehicle data that is sent is determined by the Volvo On Call Service Center.
