- Control Module Voltage Reference Output Circuit Low Voltage

DTC C0870 07

- Control Module Voltage Reference Output Circuit High Voltage

Diagnostic Fault Information

Circuit/System Description

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

acceleration sensor. The body acceleration sensors and vertical suspension 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

C0870 03

The suspension control module detected a short to ground on the 5 V reference circuit for 1.5 s.

C0870 07

The suspension control module detected a short to voltage on the 5 V reference circuit for 1.5 s.
