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 primary shaft speed sensor connector.
c. Check if the primary shaft speed sensor connector is dirty, oxidized, loose or damaged.
