KEYLESS OPERATION SYSTEM (KOS)

42B-77

3. OSS-ECU diagnosis code recheck

Code No. U1190: No receive fault detect signal

CAUTION

• If the diagnosis code No. U1190 is set, diag-

nose the CAN bus lines.

• When replacing the ECU, always check that 

the communication circuit is normal.

DIAGNOSTIC FUNCTION

When the signal from the ETACS-ECU cannot be 
received, OSS-ECU sets the diagnosis code 
No.U1190.

JUDGEMENT CRITERIA

Check Conditions

• When all the following conditions are met.

a. Power supply mode: ON
b. ETACS-ECU system voltage is at 10 to 16 V.

Judgment Criterion

• After the following condition is met, 5,000 ms or 

more have elapsed.

a. CAN signal from the ETACS-ECU cannot be 

received.

PROBABLE CAUSES

• Malfunction of the CAN bus line

• Malfunction of ETACS-ECU

• Malfunction of OSS-ECU

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnostics
Use the M.U.T.-III to diagnose the CAN bus lines.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Repair the CAN bus line (Refer to GROUP 
54C 

− Troubleshooting ).

STEP 2. M.U.T.-III other system diagnosis code
Check again if the diagnosis code is set to the 
ETACS-ECU.

Q: Is the diagnosis code set?

YES : 

Diagnose the ETACS-ECU (Refer to 

GROUP 54A, Troubleshooting ).

NO : 

Go to Step 3.

STEP 3. M.U.T.-III other system diagnosis code
Check again if the diagnosis code is set to the 
SRS-ECU.

Q: Is the diagnosis code set?

YES : 

Replace the ETACS-ECU.

NO : 

Go to Step 4.

STEP 4. Diagnosis code recheck
Check again if the diagnosis code is set to the 
OSS-ECU.
(1) Erase the diagnosis code.
(2) Turn the engine switch from the LOCK (OFF) 

position to the ON position.

(3) Check if the diagnosis code is set.

Q: Is the diagnosis code set?

YES : 

Replace the OSS-ECU.

NO : 

Intermittent malfunction is suspected (Refer 
to GROUP 00 

− How to Use 

Troubleshooting/Inspection Service Points 

− 

How to cope with Intermittent Malfunction ).

Code No. U1195 Coding not completed

CAUTION

• If diagnosis code No. U1195 is set, diagnose 

the CAN bus lines.

• When replacing the ECU, always check that 

the communication circuit is normal.

DIAGNOSTIC FUNCTION

When the coding data is not registered, OSS-ECU 
sets the diagnosis code No.U1195.

JUDGEMENT CRITERIA

Check Conditions

• When all the following conditions are met.

a. Coding is not completed.
b. For 5 seconds since the start of the reception 

of ignition status signal (ON or during crank-
ing) transmitted from ETACS-ECU.

Judgment Criterion

• Any of the coding is not completed normally.

SYMPTOM PROCEDURES

Inspection Procedure 1: Abnormality in OSS-ECU power supply and earth circuit

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 OSS-ECU cannot communicate with the 
M.U.T.-III, the power supply or earth circuit system of 
OSS-ECU may be faulty.

PROBABLE CAUSES

• Damaged harness wires and connectors

• Malfunction of OSS-ECU

DIAGNOSIS PROCEDURE

STEP 1. Resistance measurement at OSS-ECU 
connector (PGND terminal)
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Measure the resistance between the OSS-ECU 

connector (PGND terminal) and body earth.

OK: Continuity exists (2 

 or less)

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Go to Step 2.

STEP 2. Check of open circuit in PGND line 
between OSS-ECU connector and earth joint 
connector

NOTE: Before the wiring harness check, check the 
joint connector, and repair if necessary.

Q: Is the check result normal?

YES : 

Intermittent malfunction is suspected (Refer 

to GROUP 00 

− How to Use 

Troubleshooting/Inspection Service Points 

− 

How to Cope with Intermittent Malfunction ).

NO : 

Repair the connector(s) or wiring harness.

STEP 3. Resistance measurement at OSS-ECU 
connector (SGND terminal)
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Measure the resistance between the OSS-ECU 

connector (SGND terminal) and body earth.

OK: Continuity exists (2 

 or less)

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Go to Step 4.

STEP 4. Check of open circuit in SGND line 
between OSS-ECU connector and earth joint 
connector

Q: Is the check result normal?

YES : 

Intermittent malfunction is suspected (Refer 

to GROUP 00 

− How to Use 

Troubleshooting/Inspection Service Points 

− 

How to Cope with Intermittent Malfunction ).

NO : 

Repair the connector(s) or wiring harness.

STEP 5. Voltage measurement at OSS-ECU 
connector (+B1 terminal)
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Check the voltage between the OSS-ECU 

Vehicle power does not turn ON (Not possible with power supply mode ON 
only)

4

P.42B-83

Engine does not start (cranking is not performed)

5

P.42B-83

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

6

P.42B-85

Electric steering lock does not become locked. (Power supply mode is OFF.)
