STEP 7. Check the wiring harness between the receiver
antenna module connector C-08 (terminal Nos. 2, 1, 8, 12)
and the ground for short circuit.
(1) Disconnect reciever anntena module connector C-08, and
check the wiring harness.
(2) Check the wiring harness between reciever anntena
module connector C-08 (terminal No.2) and ground
OK: No continuity
(3) Check the wiring harness between reciever anntena
module connector C-08 (terminal No.1) and ground
OK: No continuity
(4) Check the wiring harness between reciever anntena
module connector C-08 (terminal No.8) and ground
OK: No continuity

(5) Check the wiring harness between reciever anntena
module connector C-08 (terminal No.12) and ground
OK: No continuity
Q: Is the wiring harness between receiver antenna module
connector C-08 (terminal Nos. 2, 1, 8, 12) and the ground
in good condition?
YES : Go to Step 8.
NO (receiver antenna module connector C-08 terminal
No.2
− ground.) : Repair the wiring harness between
receiver antenna module connector C-08 (terminal
No. 2) and the ground.
NO (receiver antenna module connector C-08 terminal
No.1
− ground.) : Repair the wiring harness between
receiver antenna module connector C-08 (terminal
No. 1) and the ground.
NO (receiver antenna module connector C-08 terminal
No.8
− ground.) : Repair the wiring harness between
receiver antenna module connector C-08 (terminal
No. 8) and the ground.
NO (receiver antenna module connector C-08 terminal
No.12
− ground.) : Repair the wiring harness between
receiver antenna module connector C-08 (terminal
No. 12) and the ground.
STEP 8. Replace the receiver antenna module, and check
whether the diagnostic trouble code is reset.
(1) Turn the ignition switch from the "LOCK" (OFF) position to
the "ON" position.
(2) Check if the DTC is set.
Q: Is the DTC set?
YES : Replace KOS-ECU and register the ID codes (Refer
to
NO : The procedure is complete.

DTC B2416: ECU internal error
.
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.
.
TROUBLESHOOTING HINTS
Malfunction of KOS-ECU
DIAGNOSIS
Required Special Tools:
• MB991958: Scan Tool (M.U.T.-III Sub Assembly)
• MB991824: Vehicles Communication Interface (V.C.I.)
• MB991827: M.U.T.-III USB Cable
• MB991910: M.U.T.-III Main Harness A
Recheck for diagnostic trouble code.
Check again if the DTC is set to the KOS-ECU.
CAUTION
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) Erase the DTC.
(3) Turn the ignition switch from "LOCK" (OFF) position to "ON"
position.
(4) Check if DTC is set.
(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?
YES : Replace KOS-ECU and register the ID codes (Refer
to
NO : The trouble can be an intermittent malfunction (Refer
to GROUP 00

DTC C1608: EEPROM Error
CAUTION
If there is any problem in the CAN bus lines, an incorrect
diagnostic trouble code may be set. Prior to this diagno-
sis, diagnose the CAN bus lines (Refer to GROUP 54C,
Trouble code diagnosis
.
DTC SET CONDITION
KOS incorporates EEPROM (nonvolatile memory), and that
EEPROM stores the TPMS, KOS and immobilizer information.
When the data in EEPROM is failed, this code is set.
.
TROUBLESHOOTING HINTS
The most likely causes for this DTC to set are:
• Damaged wiring harness and connector
• Malfunction of KOS-ECU
DIAGNOSIS
Required Special Tools:
• MB991958 Scan Tool (M.U.T.-III Sub Assembly)
• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827 M.U.T.-III USB Cable
• MB991910 M.U.T.-III Main Harness A
STEP 1. M.U.T.-III CAN bus diagnostics
Use scan tool to diagnose the CAN bus lines.
Q: Is the check result normal?
YES : Go to Step 2.
NO : Repair the CAN bus lines (Refer to GROUP 54C
−
CAN Bus Diagnostics table
). On completion,
go to Step 2.
STEP 2. Diagnostic trouble code check
(1) Turn the ignition switch to the "LOCK" (OFF) position.
(2) Turn the ignition switch to the "ON" position.
(3) Check if the DTC is set.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC C1608 set?
YES : Replace the KOS-ECU and register the ID codes
(Refer to
). Then go to Step 3.
NO : The procedure is complete.
STEP 3. Diagnostic trouble code check
(1) Turn the ignition switch to the "LOCK" (OFF) position.
(2) Turn the ignition switch to the "ON" position.
(3) Check if the DTC is set.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC C1608 set?
YES : Start over at Step 1.
NO : The procedure is complete.
