To diagnose the C1798 Lexus code, it typically requires 1.0 hour of labor.

It is common for most auto repair shops to charge between $75 and $150 per hour.
The acceleration sensor (up and down G sensor) detects the upward and downward acceleration of the vehicle and outputs it as a voltage to the Suspension Control ECU. Up and down G sensors are installed in 3 locations: 1) the Suspension Control ECU, 2) the driver side instrument panel, and 3) the passenger side instrument panel. Each up and down G sensor independently detects the upward and downward acceleration. During a test mode inspection, the Suspension Control ECU reads the fluctuations in the signal of each sensor. When the sensor cannot detect +/-1.96 m/s2 for 1 second or more during the test mode, the Diagnostic Trouble Code (DTC) is stored.
