Connector Grounds

Fig. 22 ECU connector pins # 5, 16:

1. Connect an ohmmeter between terminals as follows, Fig. 22, and the vehicle ground.
a. Pin 5 correct value: resistance less than 1 ohm.
b. Pin 16 correct value: resistance less than 1 ohm.
2. If these values are incorrect, check the electrical circuits continuity and the ground tree (on common manifold).
