TROUBLESHOOTING <OSS-ECU>

KEYLESS OPERATION SYSTEM (KOS)

42B-85

Inspection Procedure 6: Vehicle power cannot be turned OFF when the shift position is in "P." (Power
supply mode ON to ACC is possible)

CAUTION

Before replacing the ECU, ensure that the power
supply circuit, the earth circuit and the communi-
cation circuit are normal.

COMMENTS ON TROUBLE SYMPTOM

When the shift position is judged to be in the P posi-
tion based on the input of P range detection switch,
OSS-ECU can turn OFF the vehicle power supply. If
the vehicle power cannot be turned OFF (power sup-
ply mode ON to ACC is possible) when the shift is in
P position, the P range detection switch or OSS-ECU
may have a problem.

PROBABLE CAUSES

• Damaged wiring harness or connector (short to

earth in PDSW line)

• Malfunction of selector lever assembly (ON sei-

zure of P range detection switch)

• Malfunction of OSS-ECU

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III diagnosis code
Check if the diagnosis code is set to OSS-ECU.

Q: Is the diagnosis code set?

YES :

Diagnose the OSS-ECU. Refer to

P.42B-53

.

NO :

Go to Step 2.

STEP 2. Check of short to earth in PDSW line
between selector lever assembly connector and
OSS-ECU connector

NOTE: Because the conformity cannot be deter-
mined even when the digital tester is used to meas-
ure the voltage of PDSW line between the selector
lever assembly connector and OSS-ECU connector,
be sure to use the oscilloscope. (Outputs the saw-
tooth waveform of 0 to 5 V with intervals of 10 ms.)

Q: Is the check result normal?

YES :

Go to Step 3.

NO :

Repair the connector(s) or wiring harness.

STEP 3. Check of selector lever assembly (P
range detection switch)
Disconnect the selector lever assembly connector,
and check the continuity at the equipment side.

NO :

Replace the OSS-ECU and register the
chassis number (Refer to

Inspection Procedure 7: Electric steering lock does not become locked. (At power supply mode OFF)

COMMENTS ON TROUBLE SYMPTOM

The electric steering lock performs the locking opera-
tion by using the opening/closing of the door
(ON/OFF of door switch) as a trigger. If the electric
steering lock is not unlocked, the door switch circuit
system or the electric steering lock may have a prob-
lem.

PROBABLE CAUSES

• Malfunction of OSS-ECU

• Malfunction of the door switch

• Electric steering lock malfunction

• Damaged harness wires and connectors

PROBABLE CAUSES

STEP 1. M.U.T.-III diagnosis code
Check if the diagnosis code is set to OSS-ECU.

Q: Is the diagnosis code set?

YES :

Diagnose the OSS. Refer to

P.42B-53

.

NO :

Go to Step 2.

STEP 2. M.U.T.-III other system data list
Check the ETACS-ECU data list.

STEP 3.Check of the troubles
Check if the electric steering lock becomes locked

Q: Is the check result normal?

YES :

Intermittent malfunction is suspected (Refer

to GROUP 00

− How to Use

NO :

Replace the electric steering lock and
register the chassis number (Refer to
