When the ignition switch is ON, power is supplied to the pre-crash safety city sensor.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
Inspect the fuses for circuits related to this system before performing the following procedure.
PROCEDURE
INSPECT BATTERY VOLTAGE
Measure the battery voltage with the ignition switch off.
Standard voltage
11 to 14 V
Using the parts location and system diagram, check the system for blown-out fuses, open or short circuits in the wire harness(es) and connectors that are not properly connected by performing a visual check.
Tip:If the voltage is 11 V or less, replace or recharge the battery before proceeding to the next step.
