Checking Resistance In Hydraulic Unit [EM4]

Checking Resistance In Hydraulic Unit





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

Connect an ohmmeter between hydraulic unit (towards hydraulic unit) connector C/ED terminals 1 and 15.
Ohmmeter should read approx. 0 Ohms.

If reading is OK:
- Check reference lead resistance EM5. Checking Reference Lead Resistance [EM5]

If reading is incorrect:
- Check leads between hydraulic unit and hydraulic unit connector terminal 1 and 15 for open circuit as per HA2. Open Circuit [HA2]

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