Electronic power steering . Do you know anything about automotive electronic's ? Electronic power steering control module , sensor inputs an output control ? DTC'S - diagnostic trouble codes . Electrical testing ? Do you have a professional type scan tool to check input an output data , codes ?
Power Steering System Description and Operation (Non-Turbo)
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.
Torque Sensor
The PSCM uses a torque sensor as it's main input for determining the amount of steering assist. 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 torsion bar, where the torque sensor is located. The sensor consists of a compensation coil, detecting coil and 3 detecting rings. These detecting rings have toothed edges that face each other. Detecting ring 1 is fixed to the output shaft, detecting rings 2 and 3 are fixed top the input shaft. The detecting coil is positioned around the toothed edges of detecting rings 1 and 2. As torque is applied to the steering column shaft the alignment of the teeth between detecting rings 1 and 2 changes, which causes the detecting coil signal voltage to change. The PSCM recognizes this change in signal voltage as steering column shaft torque. The compensation coil is used to compensate for changes in electrical circuit impedance due to circuit temperature changes from the electrical current and voltage levels as well as ambient temperatures for accurate torque detection.
EPS Motor
The EPS motor is a 12-volt brushed DC reversible motor with a 61-amp rating. The motor assists steering through a worm shaft and reduction gear located in the steering column housing.
Power Steering Control Module (PSCM)
The PSCM uses a combination of torque sensor inputs, vehicle speed, calculated system temperature and the steering calibration to determine the amount of steering assist. When the steering wheel is turned, the PSCM uses signal voltage from the torque sensor to detect the amount of torque being applied to the steering column shaft and the amount of current to command to the EPS motor. The PSCM receives serial data from the engine control module (ECM) to determine vehicle speed. 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 PSCM nor the EPS motor are designed to handle 61 amps continuously. The PSCM will go into overload protection mode to avoid system thermal damage. In this mode the PSCM will limit the amount of current commanded to the EPS motor which reduces steering assist levels. The PSCM also chooses which steering calibration to use when the ignition is turned ON, based on the production map number stored in the BCM. The PSCM contains all 8 of the steering calibrations which are different in relation to the vehicles RPO's. The PSCM has the ability to detect malfunctions within the EPS system. Any malfunction detected will cause the IPC message center to display PWR STR (or Power Steering) warning message.

Truck will be running fine, then all of a sudden it will completely shut off. After we wait a few minutes and pump the clutch and make sure it is all the way to the floor it will start, sometimes. S


You need the engine computer scanned for fault codes, i thank you have an ignition control problem like a module or distributor pickup coil issue. These parts whenthey fail should leave fault cdes so get them read.
Next, the check engine light will pause shortly followed by the second digit of the trouble code. For example if the check engine light blinks once and pauses followed by six blinks the trouble code number would be 16. If no code is present the check engine light will stay one constantly. To restart code gathering turn the ignition key to the "off" position, wait three minutes and turn the ignition key back "on" again without starting the engine. Remove the jumper wire once code gathering is complete. To clear code after the repairs have been made remove the negative battery cable for one minute and reconnect.

Shift solenoid not engaging overdrive which


    The valve body contains six solenoid valves:
  • three PWM solenoid valves (pulse width modulation solenoid valves,
  • two shift solenoid (on/off) valves,
  • one main regulating valve (variable force solenoid).
The individual clutches and bands are supplied pressure from the PWM solenoid valves and the shift solenoid (on/off) valves and thus the gears are shifted.
The PWM solenoid valves allow direct actuation of the clutches and bands to ensure extremely smooth gear shifting through precise pressure regulation.
The shift solenoid (on/off) valves switch the hydraulic path to the clutches and bands, reducing the number of required modulating valves.
The main regulating valve (variable force solenoid) ensures that sufficient hydraulic pressure is available in all operating conditions.
PWM solenoid valves 1-3 PWM solenoid valves 1, 2 and 3 control the pressure to the bands and clutches.
Shift solenoid (on/off) valves 1 and 2 The shift solenoid (on/off) valves switch the different oil passages in the valve body to direct the pressure to the individual clutches and bands.
The use of the shift solenoid valves are needed for direct actuation of the individual clutches and bands.
Main regulating valve The main regulating valve (variable force solenoid) controls the required main line pressure for the individual transmission ranges.
The main line pressure is controlled dependent on the current engine load.
----------------------------------------------------------------------------------------------------
Electronic synchronous shift control (ESSC)
Control of shift operations
During a shift operation certain elements are released while others are actuated. Ideally this process takes place simultaneously (synchronously) to avoid jerky gear shifting.
The time for the shift operation should remain within the time limits provided.
When the shift operation is controlled conventionally, the pressure build up and reduction at the shift elements are set and defined for ideal conditions (synchronous shifting).
As there is no way of influencing the control in the event of different levels of wear in the shift elements, when the transmission has been used for a fairly high mileage it is possible that the pressure build up and reduction may no longer be synchronous.
The result or premature pressure reduction at the element to be switched off is an unwanted rise in the turbine shaft speed as the element to be switched on cannot transmit the input torque.
The result of delayed pressure reduction at the element to be switched off is an unwanted decrease in the turbine shaft speed as both shift elements transmit the input torque. In the process the torque is transmitted to the transmission housing through internal locking.
In both cases a **** will be felt during the shift operation.
In addition, wear in the shift elements leads to a lengthening of the shift operation. Therefore, shifting takes longer when the transmission has accumulated a higher mileage.
Control of shift operations with ESSC In the 4F27E automatic transmission electronic synchronous shift control (ESSC) is used.
ESSC monitors the shift operations and is able to adapt to the wear in the shift elements over the life of the transmission.
This is possible since the shift elements are actuated by modulating valves.
The system monitors the shift time whether the shift operation is synchronous.
If the PCM detects a deviation from the stored values for the shift time and synchronization of the shift operation, the pressure build up or reduction is adapted accordingly.
Throttle position (TP) sensor The TP sensor is located on the throttle body.
It supplies the PCM with information about the position of the throttle plate.
It also detects the speed of actuation of the throttle plate.
The PCM uses the signals for the following functions among other things:
  • to determine the shift timing,
  • to control the main line pressure,
  • to control the torque converter lock-up clutch,
  • for kickdown.
In case of absence of the TP signal the engine control uses the signals of the MAF and IAT sensors as a substitute signal. The main line pressure is increased and hard shifts may occur.
Mass air flow (MAF) and intake air temperature (IAT) sensor The MAF sensor is located between the air cleaner housing and the air intake hose leading to the throttle housing.
The IAT sensor is incorporated in the housing of the MAF sensor.
The MAF sensor in conjunction with the IAT sensor provides the PCM with the primary load signal.
The PCM uses the signals for the following functions among other things:
  • to control the shift operations,
  • to control the main line pressure.
If the MAF sensor fails, the signal of the TP sensor is used as a substitute.
Crankshaft position (CKP) Sensor The CKP sensor is located on the engine/transmission flange.
The CKP sensor is an inductive sensor which provides the PCM with information about the engine speed and position of the crankshaft.
The signal is used for the following functions among other things:
  • to control the torque converter lock-up clutch,
  • to check the torque converter slip,
  • to control the main line pressure.
No substitute signal is available for the CKP sensor. If the signal is not present, the engine stops.
Turbine shaft speed (TSS) sensor The TSS sensor is located in the transmission housing over the transmission input shaft.
The TSS sensor is an inductive sensor which senses the speed of rotation of the transmission input shaft.
The signal is used for the following functions:
  • to control the shift operations,
  • to control the torque converter clutch,
  • to check the torque converter slip.
If the TSS sensor fails, the signal of the output shaft speed (OSS) sensor is used as a substitute signal.

You'll need a scanner which is compatible with Hyundai's ABS system to retrieve any DTC's (Diagnostic Trouble Codes) stored in its computer. Any time the ABS light comes on, there's a DTC stored in its computer - that code will tell you where the problem exists. Then you can go from there.
