Digital Radio Control Module (HDRCM)
Description and Operation

Hybrid Digital Radio Control Module (HDRCM)


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
NOTES:


If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty
Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new
module/component.


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with
an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads into
account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required.

The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Hybrid Digital Radio Control Module
(HDRCM). For additional diagnosis and testing information, refer to the relevant Diagnosis and Testing section in the workshop

7 Initiators 8 TPMS module 9 Instrument cluster


Tire Pressure Monitoring System (TPMS) System Operation

The controlling software for the Tire Pressure Monitoring System (TPMS) is located within a Tire Pressure Monitoring System
Module. The software detects the following:

When the tire pressure is below the recommended low pressure value - under inflated tire.
The location of the tire on the vehicle that is below the recommended pressure.
Malfunction warning.

The TPMS system comprises:

Tire pressure monitoring system module located below the right-hand front seat.
Tire pressure receiver located near the gear shifter within the floor console.
Two front initiators positioned forward of the wheels and behind the fender splash shields.
Two rear initiators positioned rearward of the wheels and assembled on dedicated brackets located behind the fender
splash shields.
Four sensors, each sensor is integral with a tire valve and located within the tire; the space saver spare wheel is not
fitted with a sensor.

The four initiators are hard wired to the TPMS module. The initiators transmit 125 KHz Low Frequency (LF) signals to the tire
pressure sensors which respond by modifying the mode status within the Radio Frequency (RF) transmission. The 315 or 433
MHz RF signals are detected by the tire pressure receiver which is connected directly to the TPMS module. The received RF
signals from the tire pressure sensors are passed to the TPMS module and contain identification, pressure, temperature and
acceleration information for each wheel and tire.

The TPMS module communicates with the instrument cluster via the medium speed CAN bus to provide the driver with
appropriate warnings. The TPMS module also indicates status or failure of the TPMS or components.

Tire Location and Identification

The TPMS can identify the position of the wheels on the vehicle and assign a received tire pressure sensor identification to a
specific position on the vehicle, for example front left, front right, rear left and rear right. This feature is required because of
the different pressure targets and threshold that could exist between the front and rear tires.

The wheel location is performed automatically by the TPMS module using an 'auto-location' function. This function is fully
automatic and requires no input from the driver. The TPMS module automatically re-learns the position of the wheels on the
vehicle if the tire pressure sensors are replaced or the wheel positions on the vehicle are changed.
The TPMS software can automatically detect, under all operating conditions, the following:
one or more new tire pressure sensors have been fitted
one or more tire pressure sensors have stopped transmitting
TPMS module can reject identifications from tire pressure sensors which do not belong to the vehicle
two 'running' wheels on the vehicle have changed positions.

If a new tire pressure sensor is fitted on any 'running' wheel, the module can learn the new sensor identification automatically
through the tire learn and location process.

The tire-learn and location process is ready to commence when the vehicle has been stationary or traveling at less than 12
mph (20 km/h) for 15 minutes. This is known as 'parking mode'. The learn/locate process requires the vehicle to be driven at
speeds of more than 12 mph (20 km/h) for 15 minutes. If the vehicle speed reduces to below 12 mph (20 km/h), the learn
process timer is suspended until the vehicle speed increases to more than 12 mph (20 km/h), after which time the timer is
resumed. If the vehicle speed remains below 12 mph (20 km/h) for more than 15 minutes, the timer is set to zero and process
starts again.

Low Pressure Monitoring

The tire low pressure sensor transmits by RF (315 MHz or 433 MHz depending on market) signal. These signals contain data
which corresponds to tire low pressure sensor identification, tire pressure, tire temperature, acceleration and tire low pressure
sensor mode.

Each time the vehicle is driven, the tire pressure monitoring system module activates each LF antenna in turn. The
corresponding tire low pressure sensor detects the LF signal and responds by modifying the mode status within the RF
transmission.

The system enters 'parking mode' after the vehicle speed has been less than 20 km/h (12.5 miles/h) for 12 minutes. In parking
mode the tire low pressure sensors transmit a coded signal to the tire pressure monitoring system module once every 13
hours. If the tire pressure decreases by more than 0.06 bar (1 lbf/in²) the tire low pressure sensor will transmit more often as
pressure is lost.

As each wheel responds to the LF signal from the tire pressure monitoring system module, it is assigned a position on the
vehicle and is monitored for the remainder of that drive cycle in that position.

The TPMS uses active tire pressure sensors which are located on each wheel, inside the tire cavity. The sensor incorporates the
tire valve and is secured in the wheel by a nut on the outside of the wheel. The sensor contains a Printed Circuit Board which
houses a PTC (positive temperature coefficient)sensor, a Piezo pressure sensor, a radio receiver and transmitter and a lithium
battery.

The tire pressure sensors use the PTC sensor and the Piezo sensor to periodically measure the pressure and temperature of
the air inside the tire. The data is transmitted by RF data signals at either 315 MHz or 433 MHz dependant on market
requirements.

The RF transmission from the sensor contains a unique identification code in its transmission data. This allows the TPMS to
identify the wheel on the vehicle. If the sensor is replaced on a wheel, the new sensor identification will be learnt through the
learn and location process.

The tire pressure sensor can also detect when the wheel is rotating. In order to preserve battery power, the sensor uses
different transmission rates when the wheel is stationary or moving.


NOTE: For important information regarding the removal and fitting of tire pressure sensors and associated valves, see the
Tire Changing section.

NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. If this is the case, match the five
digits from the scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra
information read by the manufacturer-approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places,
and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads into
account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.
