Reading and Clearing Diagnostic Trouble Codes

P311 HYBRID TRANSMISSION / TRANSAXLE: ELECTRONIC SHIFT LEVER SYSTEM: DTC CHECK / CLEAR

1. CHECK FOR DTCS (Using the Techstream)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Chassis / Transmission Control / Trouble Codes.

(e) Check for DTCs and freeze frame data, and then write them down.

(f) Check the details of the DTCs.

2. CHECK FOR DTCS (Systems other than the transmission control ECU)

HINT
The transmission control ECU maintains communication with other ECUs, including the hybrid vehicle control ECU and other ECUs. Therefore, if the transmission control ECU outputs a warning, it is necessary to check and record the DTCs of all systems.

(a) If DTCs are present, check the relevant systems.

HINT
If DTCs for the CAN communication system are present in addition to other DTCs, first troubleshoot and repair any malfunctions in the CAN communication system.

3. CLEAR DTCS (Using the Techstream)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Chassis / Transmission Control / Trouble Codes.

(e) Clear the DTCs and freeze frame data.

NOTICE:
* It is not possible to clear the following DTCs using the Techstream: DTCs C2300 (Actuator System Malfunction), C2301 (Shift Changing Time Malfunction), C2303 (Short in Power Source Relay Circuit), C2304 (Open or Short Circuit in U Phase), C2305 (Open or Short Circuit in V Phase), C2306 (Open or Short Circuit in W Phase), C2307 (Power Supply) and C2309 (Open in B+ Circuit). After the repair, it is necessary to disconnect the P CON MAIN fuse and wait for at least 60 seconds to clear the DTCs.
* Clearing the DTCs will also clear the freeze frame data.

4. CLEAR DTCS (Without using the Techstream)

(a) Turn the power switch off.

(b) Remove the P CON MAIN fuses from the engine room junction block assembly located inside the engine compartment for more than 1 minute.

(c) Check for DTCs again to see if the DTCs are cleared.

NOTICE:
* If the DTCs are output, repair the parts by following the diagnostic trouble code chart.
* Clearing the DTCs will also clear the freeze frame data.
