G1043827t100 : CHECK THE FRONT CRASH SENSOR
SIGNAL RETURN CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal. 2. Wait one minute for the system to become safe.
3. Disconnect the RCM electrical connector, CR87. 4. Disconnect the front crash sensor
electrical connector, EC50. 5. Measure the resistance between CR87, pin 20 (W) and EC50,
pin 01 (W).
•
Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams.
CLEAR the DTC. TEST the system for normal operation.
-> No
GO to Pinpoint Test G1043827t101.
G1043827t101 : CHECK THE FRONT CRASH SENSOR
SIGNAL RETURN CIRCUIT FOR SHORT TO
GROUND

(W) and GROUND.
•
Is the resistance less than 10,000 ohms?
-> Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR
the DTC. TEST the system for normal operation.
-> No
GO to Pinpoint Test G1043827t102.
G1043827t102 : CHECK THE FRONT CRASH SENSOR
SIGNAL RETURN CIRCUIT FOR SHORT TO POWER
1. Measure the voltage between CR87, pin 20 (W) and GROUND.
•
Is the voltage greater than 3 volts?
-> Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR
the DTC. TEST the system for normal operation.
-> No
