ABS Main Relay: Testing and Inspection

Fig. 65 Control Relay:

1. Inspect continuity of motor relay circuit as follows:
a. Ensure there is continuity between terminals 9 and 10.
b. Ensure there is no continuity between terminals 7 and 8.
c. If continuity is not as specified, replace relay.
2. Inspect operation of motor relay circuit as follows:
a. Connect positive lead from battery to terminal 10 and negative lead to terminal 9.
b. Ensure there is continuity between terminals 7 and 8.
c. If operation is not as specified, replace relay.
3. Inspect continuity of solenoid relay circuit as follows:
a. Ensure there is continuity between terminals 1 and 9.
b. Ensure there is no continuity between terminals 2 and 5.
c. Connect two leads in reverse, and ensure there is no continuity between terminals.
d. If continuity is not as specified, replace relay.
4. Inspect operation of solenoid relay circuit as follows:
a. Connect positive lead from battery to terminal 1 and negative lead to terminal 9.
b. Ensure there is continuity between terminals 2 and 5.
c. Ensure there is no continuity between terminals 2 and 6.
d. If operation is not as specified, replace relay.
