Without Scan Tool
- Inspect vehicle height. See Figure.
- Disconnect harness connector of front and rear height control sensors.
- Connect 3 1.5 volt dry cell batteries to SHB terminal and negative to SHG terminal and apply approximately 4.5 volts between terminals. See Fig 1.
- Measure voltage between terminals SHB and SHG. Target voltage (voltage between SHFL, SHFR, SHRR and SHB) can be obtained by dividing by 2. For example, if terminal voltage between SHB and SHG is 4.5 volts, target voltage is 2.24 volts.
- Measure voltage between SHFL (SHFR, SHRR) and SHG terminals when voltage is applied. Front sensor target voltage should be plus or minus .08 volt and rear sensor should be .07 volt.
- Loosen nut and adjust positions of height control sensor link and front upper suspension arm or lower control arm by moving them up and down. See Figure. Tighten nut to specification. See TORQUE SPECIFICATIONS .
- On front sensor, when adjustment cannot be done by performing 6, loosen nuts of height control sensor link and turn link. To raise vehicle, turn clockwise and to lower turn counterclockwise. See Figure. Tighten nuts to specification. See TORQUE SPECIFICATIONS .
- Coat threads of link with sealer Three Bond 1324 or equivalent.
