and its integrity is not compromised.
 Inspect the condition of the wiring.
 Verify that all wiring and cables are securely fastened.
 Verify that the harness shows no signs of cracking, chafing,
abrasion, melting, or any other form of damage.
 Inspect unit connector and ground strap for corrosion, evidence
of moisture, or other defects.
 Inspect pneumatic connections and repair or replace those parts
that are defective (e.g., broken "B" nuts, cracked flare sleeves,
deteriorated flexible tubing, bad valves). Purge the system, if
necessary, to remove foreign matter that may have accumulated
in the tubing.

cleaning is required, utilize a soft cloth and glass cleaner. Do not
clean with alcohol-based solvents.
