B2417
LIGHTING: LIGHTING SYSTEM: B2417,B2418: Headlight Beam Level Control Motor LH Malfunction
B2418 - Headlight Beam Level Control Motor RH Malfunction
DESCRIPTION
The headlight leveling motor receives a signal from the AFS ECU to operate. The AFS ECU receives a signal indicating the operating conditions of the headlight leveling motor.
HINT
Perform a visual check of the headlight leveling motor before replacing it.
WIRING DIAGRAM
INSPECTION PROCEDURE
PROCEDURE
1. CHECK FOR DTC
(a) Clear the DTC Reading and Clearing Diagnostic Trouble Codes.
(b) Check for DTC Reading and Clearing Diagnostic Trouble Codes.
OK:
DTC B2417 or B2418 output does not occur.
NG -- PERFORM ACTIVE TEST USING TECHSTREAM (HEADLIGHT LEVELING MOTOR)
OK -- USE SIMULATION METHOD TO CHECK How To Proceed With Troubleshooting
2. PERFORM ACTIVE TEST USING TECHSTREAM (HEADLIGHT LEVELING MOTOR)
(a) Using the Techstream, perform the Active Test.
AFS
OK:
Headlight leveling motors operate normally.
NG -- READ VALUE USING TECHSTREAM (AFS ECU)
OK -- Continue to next step.
3. CHECK HEADLIGHT LEVELING MOTOR (OPERATION)
(a) Temporarily replace the headlight leveling motor with a new or normally functioning one.
HINT
* for HID Headlight Disassembly.
* for LED Headlight Disassembly.
(b) Check for DTC Reading and Clearing Diagnostic Trouble Codes.
OK:
DTC B2417 or B2418 output does not occur.
Result
C -- REPLACE AFS ECU Removal
B -- END (REPLACE HEADLIGHT LEVELING MOTOR) Disassembly
A -- END (REPLACE HEADLIGHT LEVELING MOTOR) Disassembly
4. READ VALUE USING TECHSTREAM (AFS ECU)
(a) Using the Techstream, read the Data List.
AFS
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (AFS ECU - BODY GROUND)
(a) Disconnect the A37 ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
6. CHECK HARNESS AND CONNECTOR (AFS ECU - HEADLIGHT LEVELING MOTOR)
(a) Disconnect the A37 ECU connector.
(b) Disconnect the B1 and B11 motor connectors.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
for LH
for RH
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
7. INSPECT HEADLIGHT ASSEMBLY
(a) Remove the headlight Removalfor HID Headlight, Removalfor LED Headlight).
(b) Disconnect the leveling motor connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
for LH
for RH
Result
C -- REPLACE HEADLIGHT ASSEMBLY Removal
B -- REPLACE HEADLIGHT ASSEMBLY Removal
A -- Continue to next step.
8. CHECK HEADLIGHT LEVELING MOTOR (OPERATION)
(a) Temporarily replace the headlight leveling motor with a new or normally functioning one.
HINT
* for HID Headlight Disassembly.
* for LED Headlight Disassembly.
(b) Check for DTC Reading and Clearing Diagnostic Trouble Codes.
OK:
DTC B2417 or B2418 output does not occur.
Result
C -- REPLACE AFS ECU Removal
B -- END (REPLACE HEADLIGHT LEVELING MOTOR) Disassembly
A -- END (REPLACE HEADLIGHT LEVELING MOTOR) Disassembly
