DTC C1793 Rear Acceleration Sensor (Test Mode DTC)

DESCRIPTION

DTC Detection Condition:

The acceleration sensor assembly detects the amount of vertical force applied to the vehicle when accelerating or decelerating (G (up and down)). The acceleration sensor assemblies are mounted at 3 spots, which are in the absorber control ECU and at the front and rear of the cabin, to independently detect the amount of vertical force applied to the vehicle. The acceleration sensor assembly converts the resistance, which changes according to the acceleration level, into an electric signal, and output it to the absorber control ECU.

The absorber control ECU detects the changes in each signal when performing the Test Mode check and outputs the Test Mode DTCs (C1791, C1792, C1793. if there is no change.

HINT:
- DTC Nos. C1715 and C1791 are the right front acceleration sensor assembly.
- DTC Nos. C1716 and C1792 are the left front acceleration sensor assembly.
- DTC Nos. C1717 and C1793 are the rear acceleration sensor assembly.
- Since the right front acceleration sensor assembly is built into the absorber control ECU, replace the absorber control ECU when DTCs C1716 and C1792 are output.

INSPECTION PROCEDURE

NOTE: When replacing the absorber control ECU, check the acceleration sensor assembly signal after replacement.

HINT:
- Check the condition of each related circuit connector before troubleshooting.
- When C1774 is output, inspect and repair the trouble areas indicated by C1774 first.
