Harness side: C-211

(3)

Measure the voltage between terminal No. 9 and ground.

｠

The voltage should measure 5 ± 0.5 volts.

Q:Is the measured voltage 5 ± 0.5 volts?

YES:

 Go to Step 4.

NO:

 

Check  the  KOS-ECU  connector  C-102  and  the  wiring
harness between the KOS-ECU connector C-102 (terminal
No.  5)  and  the  key  reminder  switch  connector  C-211
(terminal No. 9), and repair them if necessary. If it is normal,
replace KOS-ECU and register the ID codes. (Refer to P.
42B-12.)

NOTE: 

Check the power supply line for open circuit and

short circuit.

STEP 4. Check KOS-ECU connector C-102 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is the KOS-ECU connector C-102 in good condition?

YES:

 Go to Step 5.

NO:

 Repair the defective connector.

STEP 5. Check the wiring harness between the key reminder
switch connector C-211 (terminal No. 11) and the KOS-ECU
connector C-102 (terminal No. 31).
Check the ground wires for open circuit.

Q:Is  the  wiring  harness  between  key  reminder  switch

connector  C-211  (terminal  No.  11)  and  the  KOS-ECU

connector C-102 (terminal No. 31) in good condition?

YES:

 Go to Step 6.

NO:

 The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector. Repair the wiring
harness as necessary.

STEP 6. Replace the key reminder switch, and check
whether the diagnostic trouble code is reset.

(1)

Erase the DTC.

(2)

Turn the ignition switch from the "LOCK" (OFF) position to
the "ON" position.

(3)

Check if the DTC is set.

Q:Is the DTC set?

YES:

 Replace KOS-ECU and register the ID codes. (Refer

to P.42B-12.)

NO:

 The procedure is complete.

DTC SET CONDITION
If KOS-ECU detects an abnormality in power supply
of the unlock sensor, KOS-ECU sets the diagnostic
trouble code No. B2414.

TECHNICAL DESCRIPTION (COMMENT)
If an abnormality in power supply of the unlock sensor
is detected when power supply of it is turned on, KOS-
ECU determines that there is a problem.
