Checking Reference Lead Resistance [EM5]

Checking Reference Lead Resistance





- Ignition off.
- Disconnect hydraulic unit connector.

Connect an ohmmeter between hydraulic units connector C/ED terminal 1 (towards control module) and #3 on test box.

Ohmmeter should read approx. 0 ohms.

If reading is OK:
- Check lead between combination relay 15-pin connector terminal 9 and hydraulic unit connector C/ED terminal 15 for open circuit as per HA2. Open Circuit [HA2]

If reading is incorrect:
- Check lead between hydraulic unit connector terminal 1 and control module #3 for open circuit as per HA2. Open Circuit [HA2]
