Caution / Notice / Hint

HINT: 

• Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
• If DTC P26C6 or P26C7 is output, check the white wires with protective coating on the exhaust pipe gas control actuator sub-assembly wiring system.
• If DTC P2BF9 or P2BFA is output, check the black wires with protective coating on the exhaust pipe gas control actuator sub-assembly wiring system.
• The connector for the exhaust pipe gas control actuator sub-assembly can be connected on either the left or right side.

  When installing the wire harness after performing repairs, install it at the specified position.

  Refer to INSTALLATION [03/2017 - ]

• During troubleshooting, refer to the illustration below to check the colors of the protective coating of the exhaust pipe gas control actuator sub-assembly wire harness.
