SERVICE PROCEDURE / INFORMATION:
When battery voltage drops during high current draw conditions experienced while cranking the
engine, the VDCCM&H/U may detect an incorrect value. As a result, the Hill Holder warning lamp
in the combination meter may start to blink. In addition, the cancel alarm (“chirp” sound) for the
Hill Holder system may also occur when the engine starts. The VDCCM&H/U software has been
optimized to prevent this condition.
Should a customer report this condition and after verification, replace the VDCCM&H/U following
the removal and Installation procedures in the applicable Service Manual.
IMPORTANT: Pay close attention to the instructions supplied in the Service Manual for protecting
the vehicle finish from brake fluid along with these other CAUTIONS and NOTES included in the
procedures:
CAUTION:
•
When installing the VDCCM&H/U to the bracket - hydraulic unit, make sure there is
no oil adhered to the bolts and threads of the VDCCM&H/U. If oil is found, degrease
CAREFULLY before tightening.
•
Connect the VDCCM&H/U connector securely.
NOTE:
•
When the VDCCM&H/U is replaced with a new part, be sure to perform the selection ·
registration operation.
•
Be sure to use the Subaru Select Monitor for the selection and registration of parameter.
•
If the registration has not been properly performed, the DTC “Parameter selection error” is
detected together with the ABS/EBD/VDC warning light illumination.
