DTC Descriptor
DTC C0176 54
Control Module Temperature Sensor High Temperature
Circuit/System Description
The power steering control module monitors the temperature of the power
steering system. The power steering
control module uses voltage, current levels and input from an internal
temperature sensor to calculate an
estimated system temperature. If the power steering control module detects a
high system temperature event is
occurring, the amount of assist is decreased to reduce system temperature, in
effort to prevent thermal damage
to the power steering components.
Conditions for Running the DTC
- Ignition ON, engine running.
- Power steering system voltage is 9-16 V.
- Repetitive steering input applied.
Conditions for Setting the DTC
- Ignition ON, engine running.
- Power steering system voltage is 9-16 V.
- Repetitive steering input applied.
Conditions for Setting the DTC
The power steering control module detects a high system temperature.
Action Taken When the DTC Sets
- DTC C0176 54 is stored in memory.
- Steering assist is reduced.
Conditions for Clearing the DTC
A current DTC will clear on the next malfunction-free ignition cycle.
Diagnostic Aids
- DTC C0176 54 does not indicate that a malfunction has occurred. Rather
that the power steering control
module had to limit current to the power steering motor to avoid thermal
damage to the power steering
system components. Discuss with the customer about driving conditions when
the steering assist was
reduced.
- Ensure that no steering components down stream of the power steering
column assembly, such as ball joints, tie rod ends,
universal joints, or the steering gear assembly, are mechanically binding.

Circuit/System Verification
- Verify that the DTC sets outside of the conditions for running and
setting. Since most occurrences of this
DTC are caused by excessive driver inputs, review with the customer the
conditions under which the
DTC set. Operate the vehicle within the conditions that the customer
experienced, avoiding excessive
inputs, and verify the DTC does not reset.
If the DTC did not set outside of the conditions for running and setting
- Ignition ON.
- Verify that no steering components down stream of the power steering
column assembly are
mechanically binding. Refer to Steering Effort Hard or Too Easy in One or
Both Directions
(N40), Steering Effort Hard or Too Easy in One or Both Directions (NJ1)
- If steering components are mechanically binding, replace the
mechanically binding steering
components.
- If no steering components are mechanically binding
- Replace the Steering Gear.
- If the DTC set outside of the conditions for running and setting
- All OK. The power steering is operating as designed.
Repair Instructions
Perform the Diagnostic Repair Verification after completing the repair.
