ENTRY AND START SYSTEM(for Start Function) TERMINALS OF ECU

Disconnect the G84 and G82 connectors.

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

Tip:

Measure the values on the wire harness side with the connector disconnected.

*: In order to prevent the vehicle battery from being depleted when the vehicle is shipped long distances, a fuse that cuts unnecessary electrical load while the vehicle is being shipped is set in the circuit. If the fuse is removed, the circuit becomes open. If the fuse that is between the vehicle battery and terminal CUTB is removed and the circuit is open, the certification ECU (smart key ECU assembly) changes to a certain control mode (example: the transmission of electric waves every 0.25 seconds that form the detection area stops).

Reconnect the G82 and G84 connectors.

Measure the voltage and check for pulses according to the value(s) in the table below.

Tip:

The waveform of the steering lock actuator motor stopped can be checked without performing any particular operation.
The waveform of the steering lock actuator motor operating can be checked if either of the following operations is performed:
- To unlock the steering, bring the electrical key transmitter sub-assembly into the cabin and turn the power switch on (ACC) or on (IG).
- To lock the steering, open a door with the power switch off and the shift lever in P.

Using an oscilloscope, check the waveform of the ECU.

Tip:

The oscilloscope waveform shown in the illustration is an example for reference only. Noise, chattering, etc. are not shown.

*a	Steering lock motor not operating
*b	Steering lock motor operating

Waveform 1


Item	Content
Tester Connection	G84-29 (SLR+) - G82-11 (E)
Tool Setting	2 V/DIV., 200 ms./DIV.
Vehicle Condition	Steering lock motor stopped → Steering lock motor operating → Steering lock motor stopped*

Tip:

*: When all of the following conditions are met, open any of the doors to operate the steering lock motor.

The power switch is off.
The shift lever is in P.
While carrying the electrical key transmitter sub-assembly, the power switch is turned on (IG) and the steering is unlocked.
