Checking Resistance to Ground In Circuit to Valves [EM6]

Checking Resistance To round In Circuit To Valves





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

Connect an ohmmeter between #1 and #3 on test box.

Ohmmeter should read infinite resistance.

If reading is OK:
- Check resistance to ground on power supply to control module EM9. Checking Resistance to Ground on Power Supply to ECM [EM9]

If reading is incorrect:
- Check resistance to ground in circuit to hydraulic unit EM7. Checking Resistance to Ground of Hydraulic Unit [EM7]
