DTC B2285 Steering Lock Position Signal Circuit Malfunction


DESCRIPTION

This DTC is output when serial communication signals and LIN communication signals in the circuit between the main body ECU and steering lock actuator (steering lock ECU) are inconsistent.
УКАЗАНИЕ:
When the main body ECU is replaced with a new one and the negative (-) battery terminal is connected, the power source mode becomes the IG-ON mode. When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.
After the main body ECU or steering lock ECU is replaced, perform the registration procedures for the engine immobiliser system.

DTC No.

INSPECTION PROCEDURE

1.READ VALUE OF INTELLIGENT TESTER

  1. Connect the intelligent tester to the DLC3.

  1. Check the DATA LIST for proper functioning of the steering lock function.

    УКАЗАНИЕ:
    When using the intelligent tester with the engine switch off, turn on and off any of the door courtesy light switches repeatedly at 1.5 second intervals or less until communication between the tester and vehicle starts.

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    E50-18 (SLP) - E39-4 (SLP1)
    		Always
    		Below 1 Ω
    2C-12 (LIN1) - E39-5 (LIN)
    		Always
    		Below 1 Ω
    E50-18 (SLP) or E39-4 (SLP1) - Body ground
    		Always
    		10 kΩ or higher
    2C-12 (LIN1) or E39-5 (LIN) - Body ground
    		Always
    		10 kΩ or higher

4.CHECK MAIN BODY ECU OPERATION

  1. After replacing the main body ECU with a normally functioning ECU, check that the engine starts. Make sure that the clutch pedal is depressed at this time.

  1. Check that the engine switch mode can be changed by pushing the engine switch.

    УКАЗАНИЕ:
    Without depressing the clutch pedal, push the engine switch repeatedly. Engine switch mode should turn from off to on (ACC) to on (IG) and back to off. With the clutch pedal depressed, push the engine switch repeatedly. Engine switch mode should turn to ENGINE START from any status.
    OK:
    Engine starts normally.
