DTC Description
HPCU confirm the variant coding after applying the power. If variant coding variant is absence or improper, DTC is recognized. HPCU sets DTC P1790 when option information which is recorded in HPCU is different from that of vehicle option information. When HPCU is replaced with new one, variant coding is needed.
