(e) Read the values displayed on the Techstream.
Standard Condition:
80 to 110 kPa (0.8 to 1.1 kgf/cm2, 12 to 16 psi)
(f) Using the vacuum pump, measure the manifold absolute pressure sensor when a pressure of 67 kPa (503 mmHg, 19.8 in.Hg) is applied to the manifold absolute pressure sensor.
Standard Condition:
23 to 38 kPa (173 to 285 mmHg, 6.79 to 11.2 in.Hg)

DIAGNOSIS SYSTEM CHECK DLC3 (a) Check the DLC3. Click here INSPECT AUXILIARY BATTERY VOLTAGE (a) Measure the auxiliary battery voltage with the power switch off. Standard voltage: 11 to 14 V If the voltage is below 11 V, recharge or replace the auxiliary battery.
Front Acceleration Sensor RH Malfunction (C1715-C1717,C1796-C1798)
DESCRIPTION The acceleration sensor assembly (up and down G sensor) detects the upward and downward acceleration of the vehicle and outputs it as a voltage to the absorber control ECU. Up and down G sensors are installed in 3 locations: 1) the driver side instrument panel, 2) the passenger side inst
