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

1. Ignition ON, engine running.
2. Power steering system voltage is 9-16 V.
3. 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

1. DTC C0176 54 is stored in memory.
2. Steering assist is reduced.

Conditions for Clearing the DTC

A current DTC will clear on the next malfunction-free ignition cycle.

Diagnostic Aids

1. 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.
2. 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.

Steering Linkage Inner Tie Rod Replacement (N40)

Scheme 12

Steering Linkage Inner Tie Rod Replacement (NJ1)

The power steering system reduces the amount of effort needed to steer the vehicle. The system uses the powertrain control module, body control module, power steering control module, discrete battery voltage supply circuit, steering shaft torque sensor, steering wheel position sensor, power steering motor and the serial data circuit to perform the system functions. The power steering control module and the power steering motor are serviced with the steering column assembly. The steering shaft torque sensor and the steering wheel position sensor are not serviced separately from each other or from the steering column assembly.

Steering Shaft Torque Sensor

The power steering control module uses the steering shaft torque sensor as it's main input for determining steering direction and the amount of assists needed. The steering column has an input shaft, from the steering wheel to the torque sensor, and an output shaft, from the torque sensor to the steering shaft coupler. The input and output shafts are separated by a section of torsion bar, where the torque sensor is located. The sensor is a 5-volt dual analog inverse signal device with a valid signal voltage range of 0.25-4.75 volts. When applying torque to the steering column shaft during a right turn, the sensor's signal 1 voltage increases, while the signal 2 voltage decreases within the valid signal voltage range. When applying torque to the steering column shaft during a left turn, the signal 1 voltage decreases, wile the signal 2 voltage increases within the valid signal voltage range. The power steering control module recognizes this change in signal voltage as steering direction and steering column shaft torque.

Steering Wheel Position Sensor

The power steering control module uses the steering position sensor to determine the steering system on center position. Since the power steering motor provides a slight amount of return to center assist, the power steering control module will command the power steering motor to the steering system center position and not beyond. The sensor is a 5-volt dual analog triangle signal device with a valid signal voltage range of 0-5 volts. The sensors signal 1 and signal 2 voltage values will increase and decrease within the valid voltage range, and stay within 2.5-2.8 volts of each other as the steering wheel is turned.

Power Steering Motor

The power steering motor is a 12-volt brushless DC reversible motor with a 65-amp rating. The motor assists steering through a worm gear and reduction gear located in the steering column housing.

Power Steering Control Module

The power steering control module uses a combination of steering shaft torque sensor input, vehicle speed, calculated system temperature and steering tuning to determine the amount of steering assist. When the steering wheel is turned, the power steering control module uses signal voltage from the steering shaft torque sensor to detect the amount of torque and steering direction being applied to the steering column shaft and then command the proper amount of current to the power steering motor. The power steering control module receives a vehicle speed message from the powertrain control module via the serial data circuit. At low speeds more assist is provided for easy turning during parking maneuvers. At high speeds, less assist is provided for improved road feel and directional stability. The power steering control module nor the power steering motor are designed to handle 65 amps continuously. If the power steering system is exposed to excessive amounts of static steering conditions, the power steering control module will go into a protection mode to avoid thermal damage to the power steering components. In this mode the power steering control module will limit the amount of current commanded to the power steering motor which reduces system temperature and steering assist levels. The power steering control module must also be setup with the correct steering tuning which are different in relation to the vehicles powertrain configuration, sedan, coupe, tire and wheel size etc. The power steering control module has the ability to detect malfunctions within the power steering system. Any malfunction detected will cause the driver information center (DIC) to turn ON a warning indicator.
