De-4 Relay Diode Check At Abs Control Unit

Ensure ignition is off. Disconnect ABS control unit. Set ohmmeter to 200-ohm scale. Measure resistance between ABS control unit Blue/Orange wire (+) and relay Black wire (-). Reverse leads. If resistance increases when leads are changed, go to DE-6 VOLTAGE AT ABS CONTROL UNIT TERMINAL "B"  . If no change, go to DE-5 RELAY DIODE CHECK AT RELAY  .
