Checking Signal Lead Resistance [EM13]

Checking Signal Lead Resistance





- Ignition off.
- Disconnect combination relay 15-pin connector.
- Disconnect control module.

Connect an ohmmeter between combination relay 15-pin connector terminal 12 and #34 on test box.

Ohmmeter should read approx 0 Ohms.

If reading is OK:
- Check signal lead for short to supply EM14. Checking Signal Lead For Short-Circuit to Supply [EM14]

If reading is incorrect:
- Check lead between combination relay 15-pin connector terminal 12 and control module #34 for open circuit as per HA2. Open Circuit [HA2]
