Summary
In the Service Manual for the CROSSTREK hybrid model, the diagnostic procedures for P1C06 and P1C07, which are DTCs for checking the relay, have no steps for specifically checking the relay. Therefore, if trouble occurs in the 12 V battery relay, the Hybrid Power Control Module (HPCM) ends up being replaced even though nothing may be wrong with it.

INTRODUCTION:
This Service Information bulletin announces a revised diagnostic procedure to follow for DTCs
P1C06 and P1C07. The existing Service Manual procedures on STIS will be updated in the future.
OVERVIEW:
In the Service Manual for the CROSSTREK hybrid model, the diagnostic procedures for P1C06 and P1C07, which are DTCs for checking the relay, have no steps for specifically checking the relay. Therefore, if trouble occurs in the 12 V battery relay, the Hybrid Power Control Module (HPCM) ends up being replaced even though nothing may be wrong with it. This service bulletin provides corrections to the Service Manual diagnostics to determine the correct failed part and eliminate unnecessary HPCM replacements.
The following have been added:
- Added a relay check to the diagnostic procedures for DTCs P1C06 and P1C07.
- Added points to check between relay terminals and changed the reference values.
DTC P1C06: (12V Battery Relay Close Circuit Performance): Detects an open circuit, short-circuit to ground, and short-circuit to power in the harness of 12V battery relay close circuit.
DTC P1C07: (12V Battery Relay Open Circuit Performance): Detects an open circuit, short-circuit to ground, and short-circuit to power in the harness of 12V battery relay open circuit.
