Circuit/System Description
The suspension control module supplies a 5 V reference
voltage and a low reference to each body acceleration sensor. The
body 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
C0595 02, C0600 02, and C0605 02
The signal voltage is less than 0.5 V for 1.5 s.
C0595 05, C0600 05, and C0605 05
The signal voltage is greater than 4.5 V for
1.5 s.
C0595 0A, C0600 0A, and C0605 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 Body Acceleration
parameters. The readings should be 0 m/s² when the
vehicle is parked on a level surface.
Circuit/System Testing
- 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. |
- Ignition OFF, key out, open and close the driver door,
wait 30 s, disconnect the harness connector at the appropriate
vertical body acceleration sensor.
- Test for less than 5 Ω between the low reference
circuit terminal 3 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. |
- Ignition ON, test for 4.8-5.2 V between the
5 V reference circuit terminal 1 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. |
- Verify the scan tool Vertical Body Acceleration
parameter is less than -3 m/s².
⇒ |
If greater than the specified value, test the
signal circuit for a short to ground. If the circuit tests normal,
replace the K19 Suspension Control Module. |
- Install a fused jumper wire between the signal circuit
terminal 2 and the low reference circuit terminal 3.
- Verify the scan tool Vertical Body Acceleration
parameter is greater than 3 m/s².
⇒ |
If less than the specified value, test the signal
circuit for a short to voltage or an open/high resistance. If the
circuit tests normal, replace the K19 Suspension Control
Module. |
- If all circuits test normal, replace the vertical body
acceleration sensor and verify the DTC does not reset. If the DTC
resets, replace the K19 Suspension Control Module.
