OBD Remapping: what is it and what does it do?
OBD (‘on-board diagnostics’) is a car’s self-diagnostic and reporting capability to help pinpoint any malfunctions to be resolved.
OBD is no longer simply a case of a malfunction light illuminating – without any information about the actual problem. Today, OBD implementations provide real time data and a standardised series of diagnostic trouble codes (referred to as DTCs) via a standardised digital communications port for the various sub-systems to be health-checked.
OBD: how does it act as a warning system?
OBD can prevent minor problems turning into major ones – and prevent hefty repair bills.
The OBD system always prepares to scan your vehicle for any malfunctions and alert you to problems when the ignition is turned on. Drivers receive an early warning if a malfunction light appears on the dashboard and stays on while driving, such as the Check Engine light or Service Engine Soon warning.
