Power Source Circuit

DESCRIPTION

This circuit supplies power source voltage from the battery to terminal B of the steering lock ECU. This is used as power source for the CPU, motor, communication, and peripheral circuits.

WIRING DIAGRAM

INSPECTION PROCEDURE

1. CHECK HARNESS AND CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY - BODY GROUND)

1. Disconnect the J29 connector from the steering lock actuator assembly.

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

   Standard resistance:

   Tester connection (Symbols)	Condition	Specified condition
   J29-1 (GND) - Body ground	Always	Below 1 Ω
   J29-2 (SGND) - Body ground	Always	Below 1 Ω

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR

OK

2. CHECK HARNESS AND CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY - BATTERY)

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

   Standard voltage:

   Tester connection (Symbols)	Condition	Specified condition
   J29-7 (B) - J29-1 (GND)	Always	10 to 14 V
   J29-7 (B) - J29-2 (SGND)	Always	10 to 14 V

OK	PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
