7. CONTROL OF TEST PULSES — INPUT/OUTPUT CONTROL FUNCTIONAL UNIT

The services available are detailed in the following table:

Table 32

Input/Output Control functional unit

Service name	Description
InputOutputControlByIdentifier	The client requests the control of an input/output specific to the server.

7.1. InputOutputControlByIdentifier service

7.1.1 Message description

There is a connection via the front connector which allows test pulses to be controlled or monitored using a suitable tester.

CPR_058 This calibration I/O signal line can be configured by K-line command using the InputOutputControlByIdentifier service to select the required input or output function for the line. The available states of the line are:

• disabled,

• speedSignalInput, where the calibration I/O signal line is used to input a speed signal (test signal) replacing the motion sensor speed signal, this function is not available in CONTROL mode,

• realTimeSpeedSignalOutputSensor, where the calibration I/O signal line is used to output the speed signal of the motion sensor,

• RTCOutput, where the calibration I/O signal line is used to output the UTC clock signal, this function is not available in CONTROL mode.

CPR_059 The vehicle unit must have entered an adjustment session and must be in CALIBRATION or CONTROL mode to configure the state of the line. When the VU is in CALIBRATION mode, the four states of the line can be selected (disabled, speedSignalInput, realTimeSpeedSignalOutputSensor, RTCOutput). When the VU is in CONTROL mode, only two states of the lines can be selected (disabled, realTimeSpeedOutputSensor). On exit of the adjustment session or of the CALIBRATION or CONTROL mode the vehicle unit must ensure the calibration I/O signal line is returned to the ‘disabled’ (default) state.

CPR_060 If speed pulses are received at the real time speed signal input line of the VU while the calibration I/O signal line is set to input then the calibration I/O signal line shall be set to output or returned to the disabled state.

CPR_061 The sequence shall be:

• Establish communications by StartCommunication Service

• Enter an adjustment session by StartDiagnosticSession Service and be in CALIBRATION or CONTROL mode of operation (the order of these two operation is not important).

• Change the state of the output by InputOutputControlByIdentifier Service.

7.1.2 Message format

7.1.3 Parameter definition

CPR_064 The parameter inputOutputControlParameter (IOCP_) is defined in the following table.

Table 36
Definition of inputOutputControlParameter values
Hex	Description	Mnemonic
00	ReturnControlToECU This value shall indicate to the server (VU) that the tester does no longer have control about the calibration I/O signal line.	RCTECU
01	ResetToDefault This value shall indicate to the server (VU) that it is requested to reset the calibration I/O signal line to its default state.	RTD
03	ShortTermAdjustment This value shall indicate to the server (VU) that it is requested to adjust the calibration I/O signal line to the value included in the controlState parameter.	STA

CPR_065 The parameter controlState is present only when the inputOutputControlParameter is set to ShortTermAdjustment and is defined in the following table:

Table 37
Definition of controlState values
Mode	Hex Value	Description
Disable	00	I/O line is disabled (default state)
Enable	01	Enable calibration I/O line as speedSignalInput
Enable	02	Enable calibration I/O line as realTimeSpeedSignalOutputSensor
Enable	03	Enable calibration I/O line as RTCOutput
