DTC Confirmation Procedure:

Confirm that battery voltage is between 11 and 14 V before performing the following procedures.
 Turn ignition switch to LOCK.
 Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC), and make it 

communicate with vehicle electronic module by the data network.

 Turn ignition switch to ON.
 Using X-431 3G diagnostic tester to record and clear the DTCs stored in the TCU.
 Turn ignition switch to LOCK and wait for a few seconds.
 Turn ignition switch to ON, and then select "Read Code".
 If DTC is detected, the malfunction indicated by the DTC is current. Go to the diagnosis procedure - Step 1.
 If DTC is not detected, the malfunction indicated by the DTC is intermittent. Please refer to Intermittent 

DTC Troubleshooting.

Diagnosis Procedure

HINT:
After the fault is eliminated, verify DTC and symptom again.

a. Turn ignition switch to LOCK.
b. Disconnect the transmission wire harness connector.
c. Check if the transmission wire harness connector is dirty, oxidized, loose or damaged.

a. Turn ignition switch to LOCK and disconnect the negative 

battery cable.

b. Disconnect the connectors E-052 and E-030.
c. Check for continuity between the terminal 4 and 9 of 

connector E-052 and terminal 32 and 3 of connector E-030.

a. Turn ignition switch to LOCK and disconnect the negative 

battery cable.

b. Disconnect the wire harness connector E-030.
c. Check for continuity between the terminals 3 and 32 of 

wire harness connector E-030 and ground.
