DTC Confirmation Procedure

Confirm that battery voltage is over 12 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).
 Turn ignition switch to ON.
 Use X-431 3G diagnostic tester to record and clear the DTCs stored in the ECM.
 Select Read Code.
 If the 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 (

See page 06-18

).

Diagnosis Procedure

a. Turn ignition switch to LOCK.
b. Check ECM grounds E-026 and E-028 (

See page 06-18

).

a. Turn ignition switch to ON, start the engine and observe the signal waveform of engine speed sensor with 

an oscilloscope.

a. Turn ignition switch to LOCK.
b. Disconnect engine speed sensor connector E-016.
c. Check engine speed sensor connector.

a. Remove engine speed sensor.
b. Check and clean engine speed sensor and installation area, and check for damage, foreign matter or 

excessive movement, etc. that cause signal incorrectness.
