DTC B2415: RA module power voltage

M14209100032USA0000010000

｠

If the DTC B2352 is set, diagnose the CAN bus
lines.

DTC SET CONDITION
If  an  open  circuit  or  short  to  ground  occurs  in  the
immobilizer antenna, KOS-ECU sets the DTC B2352.

DIAGNOSIS

TECHNICAL DESCRIPTION (COMMENT)
When  the  ignition  switch  is  turned  ON,  KOS-ECU
sends  signals  to  the  receiver  antenna  module.  The
receiver  antenna  transmits  random  numbers  to  the
emergency key when it receives signals from KOS-
ECU. If an open circuit or short to ground occurs on
the wiring harness between KOS-ECU and receiver
antenna at this time, KOS-ECU determines that there
is a problem.

Data link

connector

To prevent damage to scan tool (MB991958), always turn
the  ignition  switch  to  the  "LOCK"  (OFF)  position  before
connecting or disconnecting scan tool (MB991958).

(1)

Connect scan tool MB991958 to the data link connector.

(2)

Turn the ignition switch to the "ON" position.

(3)

Diagnose the CAN bus line.

(4)

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

Q:Is the CAN bus line found to be normal?

YES:

 Go to Step 2.

NO:

 Repair the CAN bus line. (Refer to GROUP 54D,

Diagnosis P.54D-17).

STEP 2. Check receiver antenna module connector C-30
and KOS-ECU connector C-102 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.

Q:Is the eceiver antenna module connector C-30 and KOS-

ECU connector C-102 in good condition?

YES:

 Go to Step 3.

NO:

 Repair the defective connector.

DIAGNOSIS

STEP 3. Check the wiring harness between the receiver
antenna module connector C-30 (terminal No. 8, 12) and the
KOS-ECU connector C-108 (terminal No. 32, 7).

｠

Check the power supply and ground wires for open circuit.

Q:Is the wiring harness between receiver antenna module

connector  C-30  (terminal  No.  8,  12)  and  the  KOS-ECU

connector C-108 (terminal No. 32, 7) in good condition?

YES:

 Go to Step 4.

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 4. Replace the receiver antenna module, 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 trouble can be an intermittent malfunction (Refer

to GROUP 00 - How to use Troubleshooting/inspection
Service Points - How to Cope with Intermittent
Malfunction P.00-15).

DTC B2416: ECU internal error

M14209100033USA0000010000

DTC SET CONDITION
KOS-ECU sets DTC B2416 when it determines itself
to be in abnormal status.

TECHNICAL DESCRIPTION (COMMENT)
KOS-ECU determines that the abnormality is present,
if  the  data  abnormality  is  found  when  the  ignition
switch is turned ON and then EEPROM is written.

DTC C1608: EEPROM Error

M14209100152USA0000010000

If there is any problem in the CAN bus lines, an incorrect
diagnostic trouble code may be set. Prior to this diagnosis,
diagnose the CAN bus lines. (Refer to GROUP 54D, Trouble
code diagnosis P.54D-17).

TPMS DTC SET CONDITION
KOS-ECU  incorporates  EEPROM  (nonvolatile  memory),  and
that EEPROM stores the TPMS information. When the data in
EEPROM is failed, this code is set.

The most likely causes for this DTC to set are:

｠

Damaged wiring harness and connector

｠

Malfunction of KOS-ECU
