Circuit/System Description
The suspension control module supplies a 5 V reference voltage
and a low reference to each vertical wheel acceleration sensor. The
vertical wheel acceleration sensors supply a signal of 0.5-4.5 V to
the suspension control module.
Conditions for Running the DTC
System voltage is between 9-16 V.
Conditions for Setting the DTC
C0670 02 and C0675 02
The signal voltage is less than 0.5 V for 1.5 s.
C0670 05 and C0675 05
The signal voltage is greater than 4.5 V for 1.5 s.
C0670 0A and C0675 0A
| • |
The number of signal changes
is less than specified value for 2.5 s. |
| • |
Vehicle speed is greater than
30 km/h (19 MPH). |
Action Taken When the DTC Sets
| • |
The electronic suspension
control is disabled for the duration of the ignition cycle.
|
| • |
The driver information center
displays the SERVICE SUSPENSION SYSTEM message. |
Conditions for Clearing the DTC
| • |
A present DTC will clear on
the next consecutive malfunction-free ignition cycle. |
| • |
A history DTC will clear after
41 consecutive malfunction-free ignition cycles. |

Circuit/System Verification
Ignition ON, observe the scan tool Vertical Wheel Acceleration
parameters. The readings should be 0 m/s² when the vehicle is
parked on a level surface.
Circuit/System Testing
| 1. |
Ignition ON, verify that DTC
C0870 is not present. |
| ⇒ |
If the DTC is present, refer to
DTC C0870 to diagnose that DTC prior to this diagnostic. |
| 2. |
Ignition OFF, key out, open
and close the driver door, wait 30 s, disconnect the harness
connector at the appropriate vertical wheel acceleration
sensor. |
| 3. |
Test for less than 5 Ω
between the low reference circuit terminal 9 and ground.
|
| ⇒ |
If greater than the specified value, test the low
reference circuit for short to voltage or an open/high resistance.
If the circuit tests normal, replace the K19 Suspension Control
Module. |
| 4. |
Ignition ON, test for 4.8-5.2
V between the 5 V reference circuit terminal 7 and ground.
|
| ⇒ |
If less than the specified value, test the 5 V
reference circuit for a short to ground or an open/high resistance.
If the circuit tests normal, replace the K19 Suspension Control
Module. |
| ⇒ |
If greater than the specified value, test the 5 V
reference circuit for a short to voltage. If the circuit tests
normal, replace the K19 Suspension Control Module. |
| 5. |
Test for 4.8-5.2 V between the
signal circuit terminal 8 and ground. |
| ⇒ |
If less than the specified value, test the signal
circuit for a short to ground or an open/high resistance. If the
circuit tests normal, replace the K19 Suspension Control
Module. |
| ⇒ |
If greater than the specified value, test the
signal circuit for a short to voltage. If the circuit tests normal,
replace the K19 Suspension Control Module. |
| 6. |
If all circuits test normal,
replace the vertical wheel acceleration sensor and verify the DTC
does not reset. If the DTC resets, replace the K19 Suspension
Control Module. |
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
