Checking Resistance to Ground of Hydraulic Unit [EM7]

Checking Resistance To Ground In Circuit To Hydraulic Unit





- Ignition off.
- Disconnect hydraulic unit connector C/ED.

Connect an ohmmeter between hydraulic unit connector C/ED terminal 1 (towards hydraulic unit) and ground.

Ohmmeter should read infinite resistance.

If reading is OK:
- Check reference lead resistance to ground EM8. Checking Reference Lead Resistance to Ground [EM8]

If reading is incorrect:
- Check lead between hydraulic unit and hydraulic unit connector C/ED terminal 1 and 15 for short-circuit to ground as per HA3. Short Circuit to Ground [HA3]

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