DTC 97 - Accelerometer Circuit Shorted To Ground: Notes
NOTE:
For circuit and connector terminal identification, see WIRING DIAGRAM
.
The accelerometer provides additional vehicle speed reference to the EBCM. Voltage signal ranges from 2.4-2.6 volts at zero speed change (constant motion). Accelerometer voltage decreases when vehicle is accelerated and increases during deceleration.
NOTE:
Test numbers refer to test numbers on diagnostic chart.
- Checks if malfunction is currently present.
- Checks for short to ground in accelerometer signal circuit.
- Checks for short to ground in accelerometer power circuit.
- Ensures DTC was not set due to faulty accelerometer.
- Checks for possible intermittent malfunction due to a faulty EBCM.
