PSM PROGRAMMING CHANGE

COMMERCIAL VANS TECHNICAL TOPICS; APRIL 2016

Reference Number(s): TT 04/16-D, Date of Issue: April 14, 2016

SPRINTER:	MY16 FRITO-LAY 906
GROUP:	54.21 - Control unit / base module

Frito-Lay and PepsiCo regulate idle shutdown times through the PSM.
- For MY 2016 (253 units) the following has changed for idle shutdown:
  - Time has changed to 30 seconds.
  - Idle shutdown is active in park position independent of the parking brake, and in neutral position with parking brake applied.
  - Idle shutdown is not active in neutral position with the service brake applied (foot on the brake pedal).
- Function of idle shutdown up to MY 2016:
  - Idle shutdown occurred after 3 min.
  - Idle shutdown is not active in park with the parking brake not applied.
One additional potential programming change is, limiting the speed in reverse to 6 MPH (this is currently undergoing final approval at Frito).

Consider the following when working on a Sprinter with PSM with idle shutdown:

To perform a manual regeneration, or other service operations requiring extended running times, a Service Bypass Mode is provided within the PSM programming.
Perform the following to enter service bypass mode:
- Engine running
- Turn headlight switch to position 1, then parking lamp position AND then position the signal lever in the left turn position (Notice parking lights, not headlights on position 2)

NOTE: Never SCN Code a PSM as this is never needed. If a PSM is SCN coded, the customer specific programming is removed.
