HwTest Running the test with an external test plug

Description

The function runs a hardware test with an external test plug. This test verifies the operation of the CAN drivers, the KL line driver and the switch.

This test must not be run while the adapter is connected to a vehicle, because the test outputs test signals on the output pins of the OBDII connector. This can block the vehicle's CAN buses.

long HwTest(unsigned long DeviceID)

Parameters

unsigned long DeviceID - The identifier saved when the connection was established with the PassThruOpen command.

Return error codes

Definition	Description
STATUS_NOERROR	Function completed successfully
ERR_DEVICE_NOT_CONNECTED	No connection to the adapter. Possible causes: the adapter is turned off, there is no network, or the IP address is set incorrectly.
ERR_INVALID_DEVICE_ID	A non-existent adapter DeviceID was specified

Example

#include "j2534_lib.hpp"

unsigned long DeviceID;
unsigned long Ret;

Ret = HwTest(DeviceID);
if (Ret != STATUS_NOERROR)
{	// Error handling
}
