Unlock Position Sensor Signal Circuit

STEERING COLUMN: STEERING LOCK SYSTEM: Unlock Position Sensor Signal Circuit
- Unlock Position Sensor Signal Circuit

DESCRIPTION

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

PROCEDURE

1. INSPECT STEERING LOCK ACTUATOR ASSEMBLY

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





Voltage:





OK -- CHECK PUSH BUTTON START FUNCTION
NG -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY - POWER SOURCE CONTROL ECU)

(a) Disconnect the K28 connector from the steering lock actuator assembly.





(b) Disconnect the K73 connector from the power source control ECU assembly.

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

Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE STEERING LOCK ACTUATOR ASSEMBLY
