<3.0L Engine>.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 16 and ground by 

backprobing.

•  The voltage should measure 0.5 volt or less.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage 0.5 volt or less?

YES : Go to Step 17.
NO :  Go to Step 19.

STEP 17. Check PCM connector C-50 <2.4L Engine> or 
C-52 <3.0L Engine> for loose, corroded or damaged 
terminals, or terminals pushed back in the connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 18.
