Control Circuit Inspection

Check short to ground in harness
1. Ignition "OFF".
2. Disconnect Rear-LH Actuator and EPB (& ESP) Module main harness connector.
3. Measure resistance between Control terminal of Rear-LH Actuator harness connector and chassis ground.
  Specification: Infinity Ω.
4. Is the measured resistance within specifications?
  YES
  - Go to Next procedure.
  NO
  - Check for short to ground in harness.
  - Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check for open in harness
1. Ignition "OFF".
2. Disconnect Rear-LH Actuator and EPB (& ESP) Module main harness connector.

  Specification: Below 1Ω
4. Is the measured resistance within specifications?
  YES
  - Go to Next procedure.
  NO
  - Check for open in harness.
  - Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check short to battery in harness
1. Ignition "OFF".
2. Disconnect Rear-LH Actuator and EPB (& ESP) Module main harness connector.
3. Ignition "ON".
4. Measure voltage between Control terminal of Rear-LH Actuator harness connector and chassis ground.
  Specification: Approx. 0V
5. Is the measured resistance within specifications?
  YES
  - Go to Next procedure.
