IGNITION RELAY MALFUNCTION DETECTION FUNCTION
 IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it.
 IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation
coil circuit.
 If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to
alert the user to the ignition relay malfunction when the ignition switch is turned OFF.
FRONT WIPER CONTROL
IPDM E/R detects front wiper stop position by a front wiper auto stop signal.
When a front wiper auto stop signal is in the conditions listed below, IPDM E/R stops power supply to wiper
after repeating a front wiper 10 seconds activation and 20 seconds stop five times.
Control part Fail-safe operation
Cooling fan Turns ON the cooling fan relay-2 and the cooling fan relay-3 when ignition switch is
turned ON (Cooling fan operates at HI)

Front wiper The status just before activation of fail-safe control is maintained until the ignition
switch is turned OFF while the front wiper is operating at LO or HI speed.
 The wiper is operated at LO speed until the ignition switch is turned OFF if the fail-
safe control is activated while the front wiper is set in the INT mode and the front wiper
motor is operating.

NOTE:
This operation status can be confirmed on the IPDM E/R “Data Monitor” that displays “BLOCK” for the item
“WIP PROT” while the wiper is stopped.
STARTER MOTOR PROTECTION FUNCTION
IPDM E/R turns OFF the starter control relay to protect the starter motor when the starter control relay remains
active for 90 seconds.
DTC IndexINFOID:0000000003880733
NOTE:
 The details of time display are as follows.
- CRNT: A malfunction is detected now
- PAST: A malfunction was detected in the past.
 IGN counter is displayed on FFD (Freeze Frame data).
- The number is 0 when is detected now
- The number increases like 1 → 2 ··· 38 → 39 after returning to the normal condition whenever IGN OFF →
ON.
- The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.

POWER STEERING FLUID
InspectionINFOID:0000000003826225
FLUID LEVEL
1. Check fluid level with engine stopped.
2. Ensure that fluid level is between MIN and MAX.
3. Fluid levels at HOT and COLD are different. Do not confuse
them.
CAUTION:
 The fluid level should not exceed the MAX line. Excessive fluid causes fluid leakage from the
cap.
 Never reuse drained power steering fluid.
FLUID LEAKAGE
Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.
1. Run the engine until the fluid temperature reaches 50 to 80°C
(122 to 176°F) in reservoir tank, and keep engine speed idle.
2. Turn steering wheel several times from full left stop to full right
stop.
3. Hold steering wheel at each lock position for five seconds and
carefully check for fluid leakage.
CAUTION:
Never hold the steering wheel in a locked position for more
than 10 seconds. (There is the possibility that power steer-
ing oil pump assembly may be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not overtighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to ST-32, "
Inspection".
6. Check steering gear boots for accumulation of fluid leaked from steering gear.
AIR BLEEDING HYDRAULIC SYSTEM
If air bleeding is not complete, the following symptoms can be observed.
 Bubbles are created in reservoir tank.
 Clicking noise can be heard from oil pump.
 Excessive buzzing in the oil pump.
NOTE:
Fluid noise may occur in the steering gear or oil pump. This does not affect performance or durability of the
system.
1. Turn steering wheel several times from full left stop to full right stop with engine off.
CAUTION:
Fill reservoir tank with a sufficient amount of fluid so that fluid level is not below the MIN line while
turning steering wheel.
2. Start the engine and hold steering wheel at each lock position for 3 second at idle to check for fluid leak-
age.HOT (A) : Fluid temperature 50 – 80°C (122 – 176°F)
COLD (B) : Fluid temperature 0 – 30°C (32 – 86°F)
Recommended fluid : Refer to MA-11, "
Fluids
and Lubricants".
Fluid capacity : Refer to ST-37, "
General
Specifications".

STEERING WHEEL
5. Check steering wheel turning force when steering wheel has
been turned 540° from neutral position.
NOTE:
Multiply the distance (L) from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
6. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump. Regarding relief hydraulic pressure of oil
pump, refer to ST-32, "
Inspection".
RACK SLIDING FORCE
1. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to ST-16, "Exploded
View".
2. Start and run the engine at idle to make sure steering fluid has reached normal operating temperature.
3. While pulling outer socket slowly in ±11.5 mm (±0.453 in) range
from neutral position, make sure rack sliding force is within
specification.
4. If rack sliding force is not within specification, overhaul steering
gear assembly.
FRONT WHEEL TURNING ANGLE
1. Check front wheel turning angle after toe-in inspection. Refer to FSU-7, "Wheel Alignment Inspection".
2. Place front wheels on turning radius gauges and rear wheels on
stands, so that vehicle can be level.
3. Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
4. With the engine at idle, turn steering wheel from full left stop to
full right stop and measure the turning angles.Standard
