STEERING LOCK SYSTEM - Unlock Position Sensor Signal Circuit


DESCRIPTION

The unlock position sensor is one of the components in the steering lock actuator assembly. The sensor switch contact closes when the steering lock is released. The steering lock release signal is then sent to the main body ECU. Receiving the signal, the ECU permits engine start. (This prevents the engine from being started with the steering locked.)

INSPECTION PROCEDURE

NOTICE:
If the steering lock ECU (steering lock actuator assembly) is replaced, with the engine switch off and the shift lever in P, open and close the driver door to record the current lock position into the steering lock ECU (steering lock actuator assembly). If this is not performed, the engine may not start.
HINT:
When the engine switch is off, the main body ECU may occasionally go into a non-active state called sleep mode. Therefore, before proceeding with the inspection, it is necessary to perform the following steps to wake up the ECU:
With the engine switch off, open the driver door. Then (with the engine switch still off) open and close any door several times at 1.5 second intervals.
1.INSPECT STEERING LOCK ECU (STEERING LOCK ACTUATOR ASSEMBLY)

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

    Standard voltage:
    Tester Connection
    		Condition
    		Specified Condition
    E69-4 (SLP1) - E69-2 (SGND)
    1. Engine switch off
    2. Engine switch on (ACC or IG)
    		Below 1 V

  1. Disconnect the E69 connector from the steering lock ECU.

  1. Disconnect the E7 connector from the main body ECU.

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

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    E69-4 (SLP1) - E7-18 (SLP)
    		Always
    		Below 1 Ω
    E69-4 (SLP1) - Body ground
    		Always
    		10 kΩ or higher
