Circuit/System Description

The suspension control module supplies a 5 V reference voltage and a low reference to each wheel acceleration sensor. The 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 and 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

Circuit/System Verification

Ignition ON, observe the scan tool Vertical Wheel Acceleration parameters. The readings should be 0 m/s².

Circuit/System Testing

1. Verify that DTC C0870 is not set.

⇒	If the DTC is set, refer to DTC C0870 to diagnose that DTC prior to this diagnostic.

2. Ignition OFF, disconnect the harness connector at the appropriate wheel acceleration sensor.
3. 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 a an open/high resistance. If circuit tests normal, replace the K19 Electronic Suspension Control (ESC) Module.

4. Ignition ON, test for 4.8-5.2 V between the 5 V reference circuit terminal 1 and ground.

⇒	If not within the specified range, test the 5 V reference circuit for an open/high resistance. If the circuit tests normal, replace the K19 Electronic Suspension Control (ESC) Module.

5. Test for 4.8-5.2 V between the signal circuit terminal 2 and ground.

⇒	If less than the specified value, test the signal circuit for a short to ground. If the circuit tests normal, replace the K19 Electronic Suspension Control (ESC) Module.

⇒	If greater than the specified value, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K19 Electronic Suspension Control (ESC) Module.

6. Install a 3 A fused jumper wire between the signal circuit terminal 2 and the low reference circuit terminal 3. Verify the scan tool Vertical Wheel Acceleration parameter is less than -13 m/s².

⇒	If greater than the specified value, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the K19 Electronic Suspension Control (ESC) Module.

7. If all circuits test normal, replace the wheel acceleration sensor and verify the DTC does not reset. If the DTC resets, replace the K19 Electronic Suspension Control (ESC) Module.
