CAUTION / NOTICE / HINT

NOTICE:

Inspect the fuse for circuits related to this system before performing the following procedure.


HINT:

If the parking assist ECU does not operate due to a power source problem, other system DTCs may be stored due to a CAN communication interruption.


PROCEDURE

1.CHECK HARNESS AND CONNECTOR (PARKING ASSIST ECU - BATTERY AND BODY GROUND)
a.

Disconnect the O206 parking assist ECU connector.


b.

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

Standard Resistance:
Tester Connection Condition Specified Condition
O206-4 (GND1) - Body ground Always Below 1 Ω



c.

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

Standard Voltage:
Tester Connection Condition Specified Condition
O206-1 (+B) - O206-4 (GND1) Always 11 to 14 V
O206-2 (IG) - O206-4 (GND1) Ignition switch ON 11 to 14 V
Ignition switch off Below 1 V
