RELAY - DRL CONTROL












1. Measure the resistance between relay terminal COM and all other terminals. If any resistance is 5 ohms or less, replace the relay. Otherwise, continue with the test.







2. Use a jumper wire to apply ground to terminal COIL. Apply battery voltage to terminals NO and COIL. Measure the voltage at terminal COM. If the voltage is less than 10 volts, replace the relay. Otherwise, return to the pinpoint tests. Pinpoint Tests
