ACC CUT RELAYINSPECTION
1. REMOVE ACC CUT RELAY
Remove the relay box and ACC cut relay.
2. INSPECT ACC CUT RELAY CONTINUITY
a. Using an ohmmeter, check that there is continuity between terminals 1 and 2.
If there is no continuity, replace the relay.
b. Check that there is no continuity between terminals 3 and 5.
If there is continuity, replace the relay.
c. Check that there is continuity between terminals 3 and 4.
If there is no continuity, replace the relay.
3. INSPECT ACC CUT RELAY OPERATION
a. Apply battery positive voltage across terminals 1 and 2.
b. Using an ohmmeter, check that there is no continuity between terminals 3 and 4.
If there is continuity, replace the relay.
c. Using an ohmmeter, check that there is continuity between terminals 3 and 5.
If there is no continuity, replace the relay.
