DESCRIPTION

This circuit supplies power source voltage from the battery to terminal B of the steering lock ECU.

The diagnosis information of the steering lock ECU is transmitted to the Techstream via the certification ECU (smart key ECU assembly) as the steering lock ECU is not connected to the CAN communication system.

INSPECTION PROCEDURE

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.

PROCEDURE

(a) Remove the STR LOCK fuse from the engine room relay block.

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

Standard Resistance:

OK

(a) Disconnect the E26 steering lock ECU connector.

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

Standard Voltage:

OK

(a) Disconnect the E26 steering lock ECU connector.

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