Description of Frozen Values, Phone Module (PHM)

Description of frozen values, phone module (PHM)

Explanation
Not all the parameters described need to be implemented in the control module. This varies from system to system.
Frozen values are parameter values that are stored when a diagnostic trouble code (DTC) is stored.

Battery voltage, value
Measurement range: 0-28.4 V.
Normal value when the generator (GEN) is charging: 13.0-14.5 V.
The value indicates the voltage at the steering wheel module.

Distance, value
Measurement range: 0-1048575 km.
The value indicates the total mileage of the car at the time the diagnostic trouble code (DTC) was stored.

Passenger compartment temperature, value
Measurement range: -60-195 °C.
The phone module (PHM) obtains the value via the control area network (CAN).

Outside temperature, value
Measurement range: -128-127.75 °C.
The phone module (PHM) obtains the value via the control area network (CAN).

Engine running, status
The status displays whether the engine was running when the diagnostic trouble code (DTC) was stored.
No = the engine was not running
Yes = the engine was running

Time, value
The value displays the time that has passed since the diagnostic trouble code (DTC) was stored.

Functions, status
The status indicates which type of function was available when the diagnostic trouble code (DTC) was stored.
Carphone = normal carphone services available.
SOS = calls can only be made to the emergency services.
Infocom = data communication.
Unit switched off = the phone module (PHM) is switched off.

Call status
The status indicates the type of call when the diagnostic trouble code (DTC) was stored.
No activity = the phone module (PHM) is in standby mode. No ongoing calls or calls be made to/from the car.
Call from car = a number has been dialed from the car, but no answer.
Call to car = an incoming call to the car, but no answer.
Call = an ongoing call.
Call + outgoing = a call is on hold while a number is being dialed from the car. No answer.
Call + incoming = a call is on hold and there is an incoming call to the car.
Call on hold = approximately call is on hold.
Call + hold = a call is on hold and another call is ongoing.
Conference = a call with multiple participants connected

Key position, status
The status indicates the position of the ignition key when the diagnostic trouble code (DTC) was stored.
No key = no key in the ignition switch.
Position 0 = ignition key in position 0.
Position 1 = ignition key in position 1.
Position 2 = ignition key in position 2.
Position 3 = ignition key in position 3.

Control module communication, CAN/MOST, status
The status indicates which control modules on the MOST and LS-CAN networks the central electronic module (CEM) was able to communicate with when the diagnostic trouble code (DTC) was stored.
CEM OK = communication with the central electronic module (CEM), LS-CAN.
CEM nok = no communication with the central electronic module (CEM), LS-CAN.
AUD OK = communication with the audio module (AUD), MOST.
AUD nok = no communication with the audio module (AUD), MOST.
DIM OK = communication with the Driver Information Module (DIM), LS-CAN.
DIM nok = no communication with the Driver Information Module (DIM), LS-CAN.
DDM OK = communication with the Driver Door Module (DDM), LS-CAN.
DDM nok = no communication with the Driver Door Module (DDM), LS-CAN.
MMM OK = communication with the multimedia module (MMM), MOST.
MMM nok = no communication with the multimedia module (MMM), MOST.
PDM OK = communication with the Passenger Door Module (PDM), LS-CAN.
PDM nok = no communication with the Passenger Door Module (PDM), LS-CAN.
PSM OK = communication with the Power Seat Module (PSM), LS-CAN.
PSM nok = no communication with the Power Seat Module (PSM), LS-CAN.
SRS OK = communication with the Supplemental Restraint System Module (SRS), LS-CAN.
SRS nok = no communication with the Supplemental Restraint System Module (SRS), LS-CAN.
REM OK = communication with the rear electronic module (REM), LS-CAN.
REM nok = no communication with the rear electronic module (REM), LS-CAN.
SWM OK = communication with the steering wheel module (SWM), LS-CAN.
SWM nok = no communication with the steering wheel module (SWM), LS-CAN.
CCM OK = communication with the Climate Control Module (CCM), LS-CAN.
CCM nok = no communication with the Climate Control Module (CCM), LS-CAN.
UEM OK = communication with the upper electronic module (UEM), LS-CAN.
UEM nok = no communication with the upper electronic module (UEM), LS-CAN.
