Relay Freezing Causing DTCs P1C30 and U0110 – 2014 Subaru XV Crosstrek Hybrid

SEOCONTENT-START

Bulletin Number: 07-98-15; Date 01/22/16 Page 1 INTRODUCTION This bulletin announces a change to the power supply relay used for the Drive Motor Control Module (DMCM) and the cooling fan / drive motor inverter. In specific cold climate (below freezing) conditions, if there is a small amount of condensation inside the relay, it can in rare cases freeze and cause the relay to remain open which in some cases, sets DTCs P1C30 and / or U0110. PRODUCTION CHANGE INFORMATION: The new relays have been used in production since September, 2014. PART INFORMATION The part number for the new relay is 25230AA190. NOTE: The new p.n. 25230AA190 replaces the original p.n. 85201AG041 for these 2 relay applications only. The original p.n. 85201AG041 relay is used elsewhere in the vehicle and remains the correct part to use for those other applications as specified in the Parts Catalog. 1.

Bulletin Number: 07-98-15; Date 01/22/16 Page 2 SERVICE PROCEDURE / INFORMATION • If DTC P1C30 and / or U0110 are found stored in memory and the outside temperatures are (or were recently) below freezing, replace both of the power supply relays (4 and 5) as shown in the illustration above. • Record the customer’s radio station presets (and navigation favorites where applicable). • When either of the power supply relays is replaced, both the auxiliary and the engine start batteries must be disconnected, auxiliary battery first. Remove the 12mm nut from the restart battery sensor stud and remove the cable along with the ground terminal from the Auxilliary battery. IMPORTANT: DO NOT remove the sensor assembly from the restart battery terminal. • The relays are located on the left (driver) side of the DMCM mounting bracket (2). Remove the sub-trunk (tray) assembly by removing the orange retaining clip and releasing the claws on either end as shown in the illustration below. Remove the 2- 10mm hex bolts securing the DMCM mounting bracket to gain access to the relays. After replacing the relays, when re-tightening the mounting bolts, torque to 4.8 ft. lbs. • If DTC U0110 is found, in addition to replacing the relays, the DMCM must also be reprogrammed (if not already done) as per TSB 11-142-14 dated 7/1/2014. • If DTC P1C30 is found, it is likely DTCs P0C78: Battery Energy Control Module (BECM), P0CA1 and P0A7B: (ECM) and C1424: (VDC) will also be stored in their respective control modules. • Always be sure to clear any stored DTCs in the BECM, ECM and VDC as part of this repair to prevent possible confusion during future repairs.
