PINPOINT TEST G256924p15: C1460; ACCELEROMETER SENSOR SUPPLY CIRCUIT FAULTG256924t33: 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. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
^ No
GO to Pinpoint Test G256924t34.
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. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
^ No
GO to Pinpoint Test G256924t35.
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 EC1 3, pin 03 (Y). 4. Measure the resistance between CR91, pin 16 (Y) and TL34, pin 03 (Y).
^ Is either resistance greater than 5,000 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
CHECK for DTC's indicating a sensor fault. Contact dealer technical support for confirmation of possible module failure, and/or raise an EPQR.
