Checking Rotation Sensor Circuit Resistance to Ground [EL18]

Checking Rotation Sensor Circuit Resistance To Ground





- Ignition off.
- Disconnect combination relay 4-pin connector

Connect an ohmmeter between combination relay 4-pin connector terminal 2 and ground.

Ohmmeter should read infinite resistance.

If reading is OK:
- Check signal lead (+) resistance to ground EL19. Checking Signal Lead (+) Resistance to Ground [EL19]

If reading is incorrect:
- Check leads between pump motor and combination relay 4-pin connector terminal 2 and 4 for short-circuit to ground as per HA3. Short Circuit to Ground [HA3]

- If leads are OK, try another hydraulic unit as per NE. Hydraulic unit, replacement. Service and Repair
