How to Troubleshoot DTCs

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

DTC troubleshooting procedures assume the cause of the problem is still present and the TPMS indicator is still on. Do not use a troubleshooting procedure unless the system has set the DTC listed for it.

NOTE: For DTCs 11, 13, 15, and 17 (low tire pressure), the TPMS indicator comes on and the low tire pressure indicator blinks only if the DTCs are caused by a system problem rather than just low tire pressure.
  1. Ask the customer to describe the conditions when the indicator came on, and try to reproduce the same conditions for troubleshooting. Find out if the customer checked and/or adjusted tire pressures since the indicator came on.
  2. If an indicator does not come on during the test-drive, check for loose terminals, poor contact due to damaged terminals, etc. before you start troubleshooting.
  3. After troubleshooting, repair and clear the DTCs, and test-drive the vehicle. Make sure no indicators come on.
  4. Check for DTCs from other control units that are connected via F-CAN. If there are DTCs that are related to F-CAN, the most likely cause was that the ignition switch was turned to ON (II) with the TPMS control unit connector disconnected. Clear the DTCs. Check for fuel and emissions DTCs, powertrain DTCs, and troubleshoot those first.
