Check Signal Lead For Short to Ground Lead [EF6]

Check Signal Lead For Short To Ground Lead





- Ignition off.
- Disconnect control module.
- Disconnect wheel sensor.

Connect an ohmmeter between test box:
- #27 and #45 (DTC 3-1-4)
- #28 and #46 (DTC 3-1-3)
- #29 and #47 (DTC 3-1-2)
- #30 and #48 (DTC 3-1-1)

Ohmmeter should read infinite resistance.

If reading is OK:
- DTC was due to poor contact in wheel sensor connector. Check wheel sensor and control module connector (and, for rear wheel sensors connectors 24/19, 24/4 and 24/2) for loose contact as per HA5 and contact-resistance and oxidation as per HA6. Checking Leads and Connections [HA]

If reading is incorrect:
- Check leads between wheel sensor and control module for short-circuit to each other as per HA4. Short Circuit to Supply [HA4]
