Diagnosing Error Code P0685 in Honda Accord 2003

Diagnosing and resolving error code P0685 in Honda Accord 2003 can be a difficult and challenging task. The first step is to check the voltage drop, which can be done by using a multimeter to measure the voltage across the battery terminals. If there is a voltage drop, this indicates that there is an issue with the circuit, and further testing of the circuit’s continuity is necessary. This can involve checking for any breaks or shorts in the wiring harness, as well as testing for any open circuits. If a fault is detected, then it must be repaired or replaced before continuing with diagnostics.

The next step is to replace the wiring harness if necessary, and then test for any codes that may be present within the PCM (Powertrain Control Module). If any codes are found then these must be addressed before moving on to replace or update the software version of the PCM. Once all of these steps have been completed, it may be necessary to perform a hard reset of the system in order to clear out any additional codes that may have been present before attempting to diagnose any further issues.
