Diagnostic Trouble Code Chart

2004 Toyota Matrix XR, FWD, StandardSECTION Diagnostic Trouble Code Chart
WARNING: This page is about a different car, the 2004 Toyota Prius. However, it is still accessible from the selected car via links, so may be relevant.

If a trouble code is displayed during the DTC check, check the circuit listed for that code in the table below and proceed to the appropriate page.

HINT:

  • When the DTC C2300, C2301, C2304, C2305, C2306, C2307, C2311, and C2312 are detected, DTC P3102 indicating the shift control system (parking lock control) malfunctions are detected for the hybrid system as well. Because of this, the hybrid system DTCs must be cleared after clearing the shift control system (parking lock control) DTCs.
  • Remove the P CON MAIN fuse to erase DTCs C2300, C2301, C2303, C2304, C2305, C2306, and C2307 because they cannot be erased with the hand-held tester (see DTC CHECK/CLEAR DTC CHECK/CLEAR  ).
  • When a DTC is detected, the master caution light comes on and an error message is indicated on the multi-display.
  • The indicator blinks quickly when it takes long to switch between the P position status and the P position release status.
