C1460; ACCELEROMETER SENSOR SUPPLY CIRCUIT FAULT

G256924t33: CHECK THE ACCELEROMETER SENSOR SUPPLY CIRCUIT FOR SHORT TO GROUND
1. Disconnect the ASU electrical connector, CR91.
2. Measure the resistance between CR91, pin 16 (Y) and GROUND.
^ Is the resistance less than 10,000 ohms?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G256924t34: CHECK THE ACCELEROMETER SENSOR SUPPLY CIRCUIT FOR SHORT TO B+
1. Measure the voltage between CR91, pin 16 (Y) and GROUND.
^ Is the voltage greater than 3 volts?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G256924t35: CHECK THE ACCELEROMETER SENSOR SUPPLY CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the front accelerometer electrical connector, EC13.
2. Disconnect the rear accelerometer electrical connector, TL34.
3. Measure the resistance between CR91, pin 16 (Y) and EC13, pin 03 (Y).
4. Measure the resistance between CR91, pin 16 (Y) and TL34, pin 03 (Y).
^ Is either resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.
-> No
CHECK for DTCs indicating a sensor fault. Contact dealer technical support for confirmation of possible module failure,
and/or raise an EPQR.
