2003 Isuzu Ascender Problems

Electrical & Lights -- Verified

A no crank condition may occur and the IGN E fuse is blown. If this occurs our technicians recommended 3 places to inspect for wiring issues: Under the sill place at the drivers side rear door opening, along the steering column, and near the brake pedal bracket. Damaged wires will require repair and should be repositioned and protected from further damage.

Drive Train -- Verified

The transmission may develop a harsh shift condition with the Check Engine Light on and fault code P0717 stored. This is commonly cased by a failed input speed sensor (ISS), located inside the transmission. The wiring at the sensor may be found damaged. If so, the sharp edges near with ISS wiring should be filed smooth to protect the new speed sensor wiring from damage.

Electrical & Lights -- Verified

The horn may not function at times due to a faulty ground circuit in the steering column. Our technicians tell us that adding a ground strap between the upper and lower steering column mounting points will commonly correct this issue.

Drive Train -- Verified

The 4WD warning message may be displayed with a code C0327. The transfer case position sensor is commonly at fault and will require replacement.

Exhaust & Emissions -- Verified

The Check Engine Light may illuminate with a code P0606 stored. Our technicians tell us updating the powertrain control module (PCM) software will generally correct this concern.
