TECH TIPS AUGUST 2017

TECHNICAL SERVICE BULLETIN

01 DCM AND ECM SWAPPING

As a reminder, the DCM (Data Communications Module) cannot be swapped between vehicles. If you decide to swap audio units between vehicles, you must leave the DCM with its respective vehicle. If the DCM is swapped between vehicles, this will cause the telematics to become inoperable in both vehicles.

The DCM has a VIN stored internally for the vehicle's telematics subscription. The DCM receives the VIN from the ECM. If you ever need to swap an ECM between vehicles the DCM must be disabled. You can disable the DCM by unplugging it.

01 AUTHORIZATION REQUESTS

Here are a few suggestions to help us to provide you with timely replies to Authorization Requests (AR) you submit for WARRANTABLE  glass or paint claims which equal or exceed $500.00. These suggestions also apply to the ARs for long blocks outlined in the two Service Bulletins (02-109-10R & 02-122-11) that can be found on STIS.

• Use a quality camera to take your pictures. Pictures up to 5MB each can be uploaded to the AR.
• All ARs should include pictures that clearly show the condition being reported.
• Find a location in your dealership where the lighting will allow you to take quality pictures.
• Review all pictures you intend to submit prior to attaching them to your AR. Only attach quality photos that clearly show the condition being reported  .

If you have questions about what is covered under warranty, please refer to the Subaru Claims Policies and Procedures Manual to determine if the condition you are about to submit an AR for is covered.

01 CPO PROCEDURE FOR TURBOCHARGED SUBARU VEHICLES

Due to the high number of phone calls presented to the Techline, we felt it necessary to remind retailers of the correct CPO procedures for Turbocharged Subaru vehicles. Checking the CID/CVN over the phone for CPO purposes is NOT the correct procedure. The information below was published in the September 2015 TechTIPS Newsletter:

Please ensure all criteria are met before sending in a CPO CID/CVN Certification request to avoid delays. Once the vehicle has passed this part of the inspection process, you should proceed with the rest of the decision-making process on certifying the vehicle.

As the CPO 152-point inspection form indicates, if a vehicle has ANY performance modifications, it cannot be enrolled as a Subaru Certified Pre-Owned vehicle. If there are any other non-performance related modifications, the vehicle must be returned to stock, with all stock/OEM parts installed before it can be enrolled as Certified. Non-compliance to these requirements may result in chargeback to the retailer for replacements after it is sold as a Subaru CPO unit.

07 2010-2016 FORESTER, TPMS LIGHT FLASHING, SENSOR REGISTRATION ISSUES

The Techline has received a number of calls regarding flashing TPMS warning lights. After initial diagnosis, if you are even able to communicate with the TPMS system, sometimes codes are stored, but most of the time there are none. If you encounter this condition, and for example, only 3 of 4 TPMS sensors are able to be registered, always check the TPMS control module for signs of water intrusion before replacing any parts. Also, always inspect the connectors and pins at the module carefully for corrosion if this condition is verified. Most cases have been traced back to the pass-through rubber harness cover/bellows between the body and the rear gate not being fully seated as shown in the photos below. The improper seating area has been primarily on the front side which can make it hard to see if not inspected carefully. There have also been isolated cases of a missing sealing gasket on the rear roof rail mounting stud. When either of these conditions occur, water can enter the vehicle, follow down the rear gate harness and drip directly onto the TPMS control module, eventually causing internal damage as seen in the bottom photo of a damaged circuit board. If you verify this concern, make sure to thoroughly clean and fully reseat the pass through harness cover and re-check to verify any water leak has been repaired. To complete the repair, it will be necessary to replace the TPMS control module and re-register all the transmitters.

15 EYESIGHT PROGRAMMING

The procedure for replacing the Eyesight camera on the 2015 MY WRX/STI and 2018 MY Crosstrek has been changed. You must now register the EyeSight camera to the vehicle after replacement only. Please follow the appropriate Service Manual procedures to complete the calibration of the EyeSight system.

See the information below from a 2018 Crosstrek Service Manual:

15 LONG RANGE RES QUIRKS

Vehicles Affected: 

• 2015MY+ Legacy/Outback with Push Start Ignition
• 2014MY+ Forester with Push Start Ignition

Remote Engine Start Kit Part Number: 

• 2015MY+ Legacy/Outback - H001SAL100 and H001SAL101
• 2014MY+ Forester - H001SSG100 and H001SSG101

Issue/Scenario: 

Long range RES Fobs do not always start the vehicle after shutting down the RES system, opening and closing a door or cycling off the ignition

Scenario 1: 

The Technician could be facing the (factory/safety) delay after closing a door or an ignition off event which applies to cycling the ignition off with the start/stop button on the dashboard or a remote start shut down. This safety delay is normal and can last up to 30+ seconds before a remote start activation will be successful.

Solution: 

Wait at least 30+ seconds and this issue should not occur. An alternative option to waiting 30+ seconds would be to lock the doors with the factory fob (Cancels the safety delay) and then activate the remote start system with the long range fob.

Scenario 2: 

If a remote start attempt is made with a long range RES fob immediately after shutting down the remote start system, the Technician could be fighting a 5 second transmit window (2-way response) from the windshield transceiver which would block the next remote start transmission from the long range fob.

Solution: 

Wait at least 5 seconds after a remote start shut down before activating the remote start system again. After 5 seconds, this issue should not occur.
