How to Troubleshoot DTCs

WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

DTC troubleshooting procedures assume that the cause of the problem is still present and the active damper system indicator is still on. Following a troubleshooting procedure for a code that has been cleared and does not reset can result in incorrect diagnosis.

Question the client about the conditions that were present when the problem occurred, such as speed, turning, road conditions, and which mode the active damper system was selected. Try to duplicated the DTC by test-driving the vehicle under the same conditions.
Check for DTCs in the PGM-FI, A/T, and VSA system related to F-CAN stored at the same time. Troubleshoot these codes first, before troubleshooting the active damper system.
After troubleshooting, or repairs are done, clear the DTCs, and test-drive the vehicle under the same conditions that originally set the DTCs. Make sure the active damper system indicator does not come on.
