4. Test for 4.8-5.2 V between the 5 V reference circuit terminal 1 and the signal circuit terminal 6.

瀚慖f not within the specified range, test the signal circuit for short to voltage or an open/high resistance. If the circuit tests normal, replace

the EBCM.

5. Ignition OFF, disconnect the harness connector at the EBCM.

6. Test for infinite resistance between the signal circuit terminal 9 and ground.

瀚慖f not the specified value, test the signal circuit for a short to ground.

7. Connect the harness connector at the EBCM.

Note: When measuring voltage, the voltage values are based on a battery charge of 12.5 V and the steering wheel is in the center position.

8. Ignition ON, at the steering angle sensor connector harness, test for 6.8-11 V between the signal circuit terminals listed below and ground.

* Phase A terminal 3

* Phase B terminal 4

* Phase C terminal 5

瀚慖f less than the specified range, test the appropriate signal circuit for a short to ground or an open/high resistance. If the circuit tests

normal, replace the EBCM.

瀚慖f greater than the specified range, test the appropriate signal circuit for a short to voltage. If the circuit tests normal, replace the EBCM.

9. If the circuits test normal, replace the steering angle sensor.

Repair Instructions

DTC Descriptors

DTC C0711 00

- Level Control Air Pressure Sensor Malfunction Signal Invalid

Diagnostic Fault Information

Circuit Description

The automatic level control (ALC) pressure sensor sends a voltage signal to the electronic suspension control module (ESCM) that corresponds to a

pressure within the range of 30-180 psi.
