P/S Control Module Removal and Installation

Removal
1) Disconnect negative cable at battery.
2) Remove console box.
3) Disconnect connectors (1) from P/S control module
(2).
4) Disconnect connector from yaw rate / G sensor
(ESP® model).
5) Remove P/S control module (2) with bracket (3) from
floor panel.
6) Separate P/S control module and bracket.
Installation
Reverse removal procedure for installation noting the
following.
• Tighten each screw to the specified torque.
Tightening torque
P/S control module bracket screw (ABS model)
(a): 9 N·m (0.9 kgf-m, 6.5 lb-ft)
P/S control module bracket screw (ESP® model)
(a): 7 N·m (0.7 kgf-m, 5.0 lb-ft)

(b)

Torque Sensor and Its Circuit Inspection

1) Remove console box.
2) With ignition switch turned OFF, connect scan tool to
DLC or connect voltage tester between "E52-18" –
"E52-9" (main sensor) or "E52-6" – "E52-9" (sub
sensor) with connected connector (1) to P/S control
module.

3) Set torque wrench to steering wheel referring to
"Steering Force Check" for checking steering force.
4) Turn ON ignition switch without engine running and
select scan tool "Data list" mode due to check of
"TQS Main Torque", "TQS Sub Torque" and "Assist
Torque" display on scan tool when steering wheel
turned left and right (if used).
5) Check that characteristic of torque sensor (main and
sub) output voltage or scan tool data and steering
force is as following graph when steering wheel is
turned left and right. If sensor voltage or scan tool
data is out of specified value or does not vary linearly
as the following graph, check P/S control module
and its circuit.
If they are OK, replace steering gear case assembly.
