Note On INTERMITTENTS

If code sets intermittently, problem may be caused by extremely cold ambient temperatures (-40°F or less) which affect viscosity of strut fluid. Increased viscosity index may prevent actuator from moving within 6 seconds, setting a false code.

Codes may also set intermittently because of poor electrical connections, especially at strut connector. Before replacing components, check for corrosion, moisture and dirt at connector terminals, especially at actuator connector and cavity. To maintain sealing integrity, disconnect actuator connectors only when necessary. Before connecting, ensure actuator connector cavity is clean and dry, and alignment groove in connector is aligned with slot in connector cavity.

NOTE: If directed by diagnostic chart to "ENTER OUTPUT CYCLING", proceed to CONTINUOUS STRUT ACTUATOR CYCLING under SELF-DIAGNOSTIC SYSTEM .

If code sets intermittently, problem may be caused by poor electrical connections. When checking lift/dive signal, ignition must be cycled off and on twice for code to reset. If engine is cranked with transmission in gear, SSS control module shuts off, but PCM does not shut off. Under this condition, the lift/dive "handshake" is not performed, possibly setting a code.

"Handshake" may also be monitored while in ECM OUTPUTS, CYCLE ALL (EO99) mode. The EO99 value should go low and high, and the voltage at the SSS control module should go low and high. A high-to-low voltage change should also occur when the accelerator pedal is depressed quickly.
