Trouble Codes No. 1-4: Faulty Solenoid Valve Circuit(s) In Hydraulic Unit

  1. Locate check connector (Black wire) under instrument panel, right of steering column. Legacy has 22-pin connector; SVX has 20-pin connector. Turn ignition on. Ground check connector terminal using a jumper wire to check solenoid valve operation. See TROUBLE CODES NO. 1-4 (SOLENOID ACTIVATION) table. See Figure or Figure .
    WARNING: Hydraulic unit cannot be serviced or disassembled. DO NOT loosen bolts or nuts on unit.
  2. Solenoid valve should be heard activating when terminal is grounded. Each time solenoid activates, system circuit is interrupted. To test circuit, ignition must be turned off and back on. If solenoid valve(s) does not activate, replace hydraulic unit.
  3. If all solenoid valves are okay, turn ignition on. Verify voltage between specified terminals and ground is zero volts as solenoid activates. Each time solenoid activates, system circuit is interrupted. To test circuit, ignition must be turned off and then on. See TROUBLE CODES NO. 1-4 (CONTROL UNIT SIDE) table. See Figure or Figure .
