- Summary
- The Newmar Engineering Department discovered that HWH changed the step programming for 2020 coaches, causing the curb sensor not to function as originally designed. The new replacement version (A59650-4) will stop the auto level function any time the curb sensor activates after the two-second delay. If the engine is running, the auto level function will stop and air up the coach’s air bags when the curb sensor is activated.
