What does the p0690 code on a car mean?
What the P0690 code means. P0690 is an OBD-II generic code for a high voltage problem with the power supply to the ECM/PCM. This means the vehicle’s computer is not receiving voltage that is within the manufacturer’s parameters.
When is a power relay code p0690 stored?
When a code P0690 is stored, it means that the powertrain control module (PCM), has detected an abnormality in the relay which supplies it with voltage. This particular code will be stored if power relay sensor circuit voltage exceeds the maximum allowable parameter.
What kind of diagnostic scanner is needed for p0690?
A diagnostic scanner and a digital volt/ohmmeter (DVOM) will be required to diagnose a code P0690. A source of reliable vehicle information will also be necessary. From it you will glean diagnostic flow charts, wiring diagrams, connector face views, connector pin-out charts, and component locators.

Where are the trouble codes on a Cadillac?
These are listed in numerical order for easy searching. When retrieving Cadillac trouble codes with an OBD II scan tool, proceed as follows: 1. Connect scan tool to the 16-pin data link connector (DLC) located underneath the steering column. The connector may have a removable cover. 2. Turn the ignition on. 3.
