CHECK HARNESS AND CONNECTOR (STEERING LOCK ECU - BATTERY)
STEERING LOCK SYSTEM - Power Source Circuit |
DESCRIPTION
This circuit supplies voltage from the battery to terminal B of the steering lock ECU (steering lock actuator assembly). This circuit is used as power source for the steering lock ECU (steering lock actuator assembly), motor, communication, and peripheral circuits.
WIRING DIAGRAM
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.CHECK HARNESS AND CONNECTOR (STEERING LOCK ECU - BODY GROUND) |
Disconnect the E69 connector from the steering lock ECU.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection
| Condition
| Specified Condition
|
E69-1 (GND) - Body ground
| Always
| Below 1 Ω
|
E69-2 (SGND) - Body ground
| Always
| Below 1 Ω
|
| REPAIR OR REPLACE HARNESS OR CONNECTOR |
