Circuit/System Verification

1. Ignition ON, observe the scan tool EBCM BPP parameter while applying and releasing the brake pedal. The reading should change between

Applied and Released.

瀚慖f the parameter does not change between applied and release, replace the EBCM.

2. Replace the BPMV.

DTC Descriptor

DTC C0176 54

- System Thermal Error Temperature High

Circuit/System Description

The PSCM uses a combination of commanded motor voltage and current levels to calculate an estimated power steering system temperature. If the

PSCM detects a high system temperature event is occurring, the amount of assist is reduced to lower system temperature to prevent thermal damage

to the power steering components.

Condition for Running the DTC

The ignition is ON.

Conditions for Setting the DTC

The PSCM detects a high system temperature.
