Anti-Lock Relay
- Remove anti-lock relay located at left rear of engine compartment. Measure resistance between specified pairs of relay terminals. See ANTI-LOCK RELAY RESISTANCE table. See Fig 1 . If resistance is as specified, go to next step. Replace relay if resistance is not as specified.
- Connect battery voltage to relay terminal No. 5. Connect terminal No. 4. to ground. Resistance between terminals No. 1 and 6 should be less than 5 ohms. Resistance between terminals No. 3 and 6 should be more than 10,000 ohms. If resistance is as specified, go to next step. Replace relay if resistance is not as specified.
- Connect battery voltage to relay terminal No. 7. Connect terminal No. 8 to ground. Resistance between terminals No. 1 and 2 should be less than 5 ohms. If resistance is as specified, go to next step. Replace relay if resistance is not as specified.
- Disconnect jumper wires from relay. Set DVOM to diode check mode. With positive lead of DVOM connected to relay terminal No. 7 and negative lead connected to terminal No. 6, continuity should exist. Transpose DVOM leads. Continuity should not exist. Replace relay if continuity is not as specified.
