Check Signal Lead Resistance to Ground [EH7]

Check Signal Lead Resistance To Ground





- Ignition off.
- Disconnect connector C/ED.
- Disconnect control module.

Connect an ohmmeter between #1 and #13 on test box.

Ohmmeter should read infinite resistance.

If reading is OK:
- Check ground lead resistance to ground EH8. Check Ground Lead Resistance to Ground [EH8]

If reading is incorrect:
- Check lead between hydraulic unit connector C/ED terminal 13 and control module #13 for short-circuit to ground as per HA3. Short Circuit to Ground [HA3]
