Code No.B2419
LF antenna voltage short
caution |
When replacing the ECU, always
check that the communication circuit is normal.
|
DIAGNOSTIC FUNCTION
When a short to power supply is detected in the wiring harness in between the inside and
outside transmission antenna assembly, KOS-ECU sets the diagnosis code No.B2419.
note |
When the diagnosis code No.B2419 is set, KOS-ECU does not perform the certification with
the keyless operation key.
|
JUDGMENT CRITERIA
When an abnormality is found with the wiring harness in between the inside and outside transmission
antenna assembly, KOS-ECU determines that a problem has occurred.
PROBABLE CAUSES
- Damaged wiring harness and connectors
- Malfunction of the KOS-ECU
DIAGNOSIS PROCEDURE
STEP 1. Check the wiring harness between KOS-ECU connector
and each inside and outside transmission antenna assembly connector.
Check the following wiring harnesses for short to power supply.
- Check of short to power supply, short to earth, and open
circuit in EDRP, EDRG line between KOS-ECU connector and outside transmission antenna assembly
(driver’s side) connector
- Check of short to power supply, short to earth, and open circuit in EASP, EASG line
between KOS-ECU connector and outside transmission antenna assembly (passenger’s side)
connector
- Check of short to power supply, short to earth, and open circuit in INFP, INFG line
between KOS-ECU connector and inside transmission antenna assembly (front) connector
- Check of short to power supply, short to earth, and open circuit in INRP, INRG line
between KOS-ECU connector and inside transmission antenna assembly (rear) connector
- Check of short to power supply, short to earth, and open circuit in EGTP, EGTG line
between KOS-ECU connector and outside transmission antenna assembly (tailgate) connector
Q.
Is the check result normal?
Go to Step 2
Repair the connectors or wiring harness.
STEP 2. Check whether the diagnosis code is reset.
|
(1)Erase the diagnosis code.
|
|
(2)Turn the power supply mode of the engine switch from OFF to ON.
|
|
(3)Check if the diagnosis code is set.
|
Q.
Is the diagnosis code set?
Replace KOS-ECU and register the ID codes (Refer to ).
The diagnosis is complete.
