ELECTRO HYDRAULIC POWER ASSIST STEERING (EHPAS) ON-BOARD DIAGNOSIS

id060200814100
On-Board Diagnostic (OBD) Test Description
• The aBO test inspects the integrity and function of the EHPAS and outputs the results when requested by the
specific tests.
• On-board diagnostic test also:
- Provides a quick inspection of the EHPAS usually performed at the start of each diagnostic procedure.
- Provides verification after repairs to ensure that no other faults occurred during service.
• The aBO test is divided into 2 tests:
- Read/clear diagnostic results, PIO monitor and record.

Read/clear diagnostic results

• This function allows reading or clearing of OTCs in the EHPAS CM memory.

PID/Data monitor and record

• This function allows access of certain data values, input signals, calculated values, and system status
information.

4. Verify the PID data according to the directions on
the screen.

Note
• The PID data screen function is used for monitoring the calculated value of input/output signals in the
module.Therefore, if the monitored value of the output parts is not within the specification, it is necessary
to inspect the monitored value of input parts corresponding to the applicable output part control. In
addition, because the system does not display an output part malfunction as an abnormality in the
monitored value, it is necessary to inspect the output parts individually.

Intermittent Concern Troubleshooting

Vibration method
• If a malfunction occurs or becomes worse while driving on a rough road or when the engine is vibrating,
perform the following steps.

Note
• There are several reasons why vehicle or engine vibration could cause an electrical malfunction. Inspect
the following:
Connectors not fully seated.
- Wiring harnesses not having full play.
- Wires laying across brackets or moving parts.
- Wires routed too close to hot parts.
• An improperly routed, improperly clamped, or loose wiring harness can cause wiring to become pinched
between parts. .
• The connector joints, points of vibration, and places where wiring harness pass through the firewall, body
panels and other panels are the major areas to be inspected.

Inspection method for switch and/or sensor connectors or wires

1. Connect the M-MDS to the DLC-2.
2. Switch the ignition to ON (engine off).

Note
• If the engine starts and runs, perform the following steps at idle.

3. Access PIDs for the switch you are inspecting.

4. Turn the switch on manually.
5. Slightly shake each connector or wiring harness
vertically and horizontally while monitoring the ::::.
PID.
• If the PID value is unstable, inspect for poor

AIR BLEEDING
id061400800200

Note
• Verify that the strainer is installed to the sub
tank of the vehicle being serviced because
the air bleeding procedure differs depending
on whether it has a strainer or not.

06-14-3
 POWER STEERING
Air bleeding (vehicles without strainer)

Caution
• Do not maintain the steering wheel fully turned for 5 s or more. The oil temperature could rise and
negatively affect the oil pump.

1. Inspect the fluid level. (See 06-14-6 POWER STEERING FLUID INSPECTION.)
2. Turn the steering wheel fully to the left and right several times.
3. Reinspect the fluid level.
• If the fluid level has dropped, add fluid.
4. Repeat Steps 2-3 until the fluid level stabilizes.
5. Start the engine and idle it.
6. Turn the steering wheel fully to the left and right several times.
7. Repeat Step 6 until the fluid is no longer foamy and the fluid level has not dropped.
8. Inspect the fluid level and, if the fluid level has dropped, add fluid to a level between MAX and MIN on the sub
tank.

Air bleeding (vehicles with strainer)

Caution
• If the strainer is removed, impurities may penetrate the power steering system and damage it. To
prevent this, always bleed air with the strainer installed.
• Do not maintain the steering wheel fully turned for 5 s or more. The oil temperature could rise and
damage the oil pump.

Note
• Add fluid and bleed air using the following procedure. Otherwise, additional time will be required to add
fluid because of mesh resistance.

Fluid level adjustment

Note
• The following procedure is for adding (adjusting) fluid if the lack of fluid level has dropped as a result of
fluid leakage.

1. Working with two people, one person protects the area around the sub tank using a cloth and adds fluid to the
sub tank.

Caution
• Do not spread a cloth near the drive belt, otherwise the cloth could get caught in the drive belt
when starting the engine causing damage to parts in the engine compartment.

2. The other person starts the engine and idles it.

3. Turn the steering wheel fully to the left and right slowly several times.
• If the steering wheel operation speed is too fast, the fluid may spatter from the filler port. Do not exceed the
steering wheel operation speed reference value.

Steering wheel operation speed (reference value)

90 0 /s

4. Inspect the fluid level and, if the fluid level has dropped, repeat Step 1-3 until the level is between MAX and
MIN on the sub tank while idling the engine.

3. Add fluid until fluid escapes from the return hose.

4. Assemble the return hose to the power steering
pipe component.
5. Working with two people, one person protects the
area around the sub tank using a cloth and adds
fluid to the sub tank.

Caution
• Do not spread a cloth near the drive belt,
otherwise the cloth could get caught in
the drive belt when starting the engine
causing damage to parts in the engine
aaxjjw00006037
compartment.

6. The other person starts the engine and idles it.

7. Turn the steering wheel fully to the left and right slowly several times.
• If the steering wheel operation speed is too fast, the fluid may spatter from the filler port. Do not exceed the
steering wheel operation speed reference value.

Steering wheel operation speed (reference value)
