B2285

THEFT DETERRENT / KEYLESS ENTRY: SMART KEY SYSTEM (for Start Function): B2285: Steering Lock Position Signal Circuit Malfunction
B2285 - Steering Lock Position Signal Circuit Malfunction

DESCRIPTION

The power management control ECU and steering lock actuator (steering lock ECU) are connected by a cable and the LIN communication line. This DTC is stored when the steering lock position signal information from the cable and the steering lock position signal information from the LIN communication line are inconsistent.

HINT
When the power management control ECU is replaced with a new one and the cable is connected to the negative (-) battery terminal, the power source mode is reset to on (IG). When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.

INSPECTION PROCEDURE

NOTICE:
* When using the Techstream with the engine switch off to troubleshoot: Connect the Techstream to the vehicle and turn a courtesy light switch on and off at 1.5 second intervals until communication between the Techstream and vehicle begins.
* Before performing the inspection, check that there are no problems related to the CAN communication system and LIN communication system.
* Inspect the fuses for circuits related to this system before performing the following inspection procedure.
* After replacing the steering lock actuator assembly (steering lock ECU), perform key ID code registration Engine Immobilizer System (w/ Smart Key System).

PROCEDURE

1. CHECK FOR DTC (LIN COMMUNICATION SYSTEM)

(a) Clear the DTCs Smart Key System (for Start Function).

(b) Check for DTCs Smart Key System (for Start Function).

OK:

LIN communication system DTCs B2287 and B2785 are not output simultaneously.

NG -- GO TO DTC B2287 B2287
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (BATTERY - POWER MANAGEMENT CONTROL ECU) B2271

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (POWER MANAGEMENT CONTROL ECU - BODY GROUND) B2271

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

4. INSPECT STEERING LOCK ACTUATOR ASSEMBLY (STEERING LOCK ECU)

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





Standard Resistance:

NG -- REPLACE STEERING LOCK ACTUATOR ASSEMBLY (STEERING LOCK ECU) Removal
OK -- Continue to next step.

5. CHECK HARNESS AND CONNECTOR (POWER MANAGEMENT CONTROL ECU - STEERING LOCK ECU)

(a) Disconnect the F80 power management control ECU connector.

(b) Disconnect the F68 steering lock ECU connector.

(c) 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. READ VALUE USING TECHSTREAM (STEERING UNLOCK SWITCH)

(a) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / Power Source Control / Data List.

(e) According to the display on the Techstream, read the Data List.

Power Source Control





OK:

ON (steering lock released) or OFF (steering lock locked) appears on the screen according to the steering lock condition.

NG -- REPLACE POWER MANAGEMENT CONTROL ECU Removal

OK -- REPLACE STEERING LOCK ACTUATOR ASSEMBLY (STEERING LOCK ECU) Removal
