After each repair, perform TEST VER-1.
CAUTION: Always turn ignition switch to OFF position before disconnecting or connecting any module connector.

Using an external ohmmeter, check resistance between Powertrain Control Module (PCM) connector terminals No. 7 (Orange wire) and No. 26 (Violet/Brown wire). If resistance is less than 5 ohms, repair short between Orange wire and Violet/Brown wire.
If resistance is more than 5 ohms, check resistance between PCM connector terminals No. 7 (Orange wire) and No. 46 (White/Black wire). If resistance is less than 5 ohms, repair short between Orange wire and White/Black wire. If resistance is more than 5 ohms, replace PCM.
