TECHNICAL SERVICE BULLETIN
| SUBARU: | 2019-20 Forester, Ascent |
APPLICABILITY
2019-20MY Forester
2019-20MY Ascent
INTRODUCTION
This bulletin replaces TSB 07-143-18R and announces additional changes made to the PRG control module. These changes are in response to a limited number of customer concerns regarding the rear gate not opening when operating the gate mounted switch, dashboard switch or the rear gate button on the key fob. In addition to ensuring proper PRG system operation, the new logic also optimizes the PRG communication function. The change will prevent excessive dark draw which may over time, cause a low battery condition.
Additional enhancements applicable to FORESTER ONLY at this time:
- When the PRG operates with an increased load (e.g. weight of snow added or frozen/binding rear gate stays), the PRG does not resume normal operation after being closed electrically or manually.
- When the PRG is closed electrically after being left open for a certain period of time, an unusual "beep" sound is heard before the normal closing "beep" sound occurs.
PRODUCTION CHANGE INFORMATION
The new PRG control modules were incorporated into production as follows:
- Forester: Starting with VIN LH477261
- Ascent: Start of 2020MY production.
