Reverse warning system (does not apply to XC90 2003-, S80 2004-, V70/XC70 2005- and S60 2005-)




The reverse warning system consists of a control module and four sensors. The control module is installed in the cargo compartment of the car behind the right side panel.
The reverse warning system's control module is directly connected to control module accessory electronics (AEM). Communication between the reverse warning system's control module and accessory electronic module (AEM) consists of a 0V/12V pulsating signal, which comes at more frequent intervals in case of reduced distance to an object.
The reverse warning system's control module is supplied with voltage and connected to ground via the accessory electronic module (AEM).
The four sensors are installed in the rear bumper of the car. The sensors function as transmitters and receivers.
The sensors transmit ultrasound which it then measures time by.
The signal is sent to the accessory electronic module (AEM) as a digital pulse.
There are two versions of the reverse warning system (accessory):
- One for early versions, which isnotconnected to the car's CAN-net. This version does not use accessory electronic module (AEM).
- One for late versions, which is connected to the car's CAN-net via accessory electronic module (AEM).
The difference between the early and late versions can be seen from the chassis number in the table below.





(1) applies to cars manufactured in production plant 1.
(2) applies to cars manufactured in production plant 2.
Information regarding which production plant a car is manufactured in can be found in the VIN number. The seventh position from the right in the VIN specifies the production plant.
Control module audio (AUM) is required for the reverse warning system to function.
When post-installing the reverse warning system the car must be configured using new software which is carried out via VIDA.
There are diagnostics for the reverse warning system.

Timer start of the electric parking heater




A timer control function can be connected to the electrical parking heater which is controlled via the accessory electronic module (AEM).
The system consists of:
- A relay for the electrical parking heater
- Wiring between the relay and accessory electronic module (AEM).
The relay is mounted on the engine block heater and controls the electrical parking heater and relay passenger compartment socket.
The relay acts as a switch and is supplied with power and controlled via the wiring from the accessory electronic module (AEM).
The relay is connected to the ground terminal in the engine compartment.
When post-installing the timer start system for the electrical parking heater the car must be configured using new software which is carried out via VIDA.
There are diagnostics for the relay/control signal.

Remote controlled parking heater
There are two ways to remote control the parking heater. Via the mini-call system and via remote control. There are also two types of parking heater, an electrical parking heater and a gasoline or diesel parking heater. The type of heater to be activated via remote start must be preset in the car's driver information module (DIM).
Remote start using the remote control cannot be combined with remote start via the mini call system.
To use the remote start function for the electrical parking heater, the "Timer start of the electric parking heater" function must be installed.

Remote starting via the mini call system (certain markets only)




The remote start system for the parking heater consists of a mini-call unit positioned under the parcel shelf (applies to the S60, S80) or behind the right-hand side panel (applies to the V70/V70XC) in the cargo compartment of the car.
The mini-call unit is directly connected with voltage supply, ground connection as well as start/stop signal to the accessory electronic module (AEM).
The mini-call unit is continuously supplied with voltage via the accessory electronic module (AEM) since it must be active all the time to be able to receive start and stop signals.
The remote start system for the parking heater is remote controlled using a normal telephone via the existing mini call network which is available in certain markets.
When installing the remote start warning system the car must be configured using new software. Configuration is carried out via VIDA.
There are diagnostics for the remote start system.

Remote start via the remote control




The remote start system starts and stops the parking heater via a remote control instead of via mini call.
The remote start system consists of a remote control and a receiver for the remote control as well as a contact relay mounted at the accessory electronic module (AEM). The receiver is supplied with voltage and connected to ground via a branching connection at the accessory electronic module (AEM).
Communication between receiver and the accessory electronic module (AEM) consists of a start or stop signal.
The remote start system with remote control is available as accessory for the accessory electronic module (AEM) for cars of later versions.
The difference in chassis numbers between the two versions is shown in the table.





There are three LR03 (AAA) batteries in the remote control.
The remote control must be synchronized with the receiver.
When installing the remote start warning system the car must be configured using new software. Configuration is carried out via VIDA.

Alarm signal outputs
An external (aftermarket) alarm unit can be connected to the accessory electronic module (AEM). The system consists of four output signals that via a cable harness can be used as input signals in the external alarm system. The accessory electronic module (AEM) uses the existing CAN-network to receive/transmit signals that describe the car's alarm, key, and door status.
The alarm signal function is available as accessory for the accessory electronic module (AEM) for cars of later versions.
The difference in chassis numbers between the two versions is shown in the table.

Telemute function for non-integrated mobile phones
With the telemute function, the audio module (AUM)/ audio control module (AUD), is muted when the cell phone rings.
The design consists of a signal input and a signal output. The input signal is digital (0V/12V) and the output signal is a Controller area network (CAN) communication.
The telemute function is available as accessory for the accessory electronic module (AEM) for cars of later versions.
The difference in chassis numbers between the two versions is shown in the table.

Aftermarket radio unit
The design consists of a signal input and four signal outputs on the accessory electronic module (AEM).
The input signal is an analogue +12V mute signal, from either the reverse warning system or the non-integrated hands free system.
Two output signal are pulse width modulated signals for the lighting rheostat signal position and the speed sensitive volume signal.
One output signal is a digital 12V mute signal to the radio unit.
One output signal is a +30 supply for an external aerial amplifier.
When installing an after market radio unit, the car must be configured using new software. Configuration is carried out via VIDA.
The function is available as accessory for the accessory electronic module (AEM) for cars of later versions.
The difference in chassis numbers between the two versions is shown in the table.

Signal output for RTI (road traffic information) (Japan only)
The signal output consists of four output signals of which one is a pulsed speed signal (0V/12V), one for the brightness for the display lighting and one for indicating that reverse gear has been engaged.
The fourth signal is to deploy a relay which then controls the power supply to the navigation system.
The signal output is available as accessory for the accessory electronic module (AEM) for cars of later versions.
The difference in chassis numbers between the two versions is shown in the table.
