Streamlining Diagnostics and Electrical Relearns

This technical reference eliminates guesswork and accelerates diagnostic workflows for complex safety and electrical faults. It details the precise operation of the Sensing and Diagnostic Module (SDM), SIR coil assemblies, and Side Impact Sensors (SIS). Technicians will find accurate code definitions and troubleshooting trees for system errors, including low or out-of-range resistance in deployment loops. The text strictly outlines the removal and installation processes for seat-mounted airbags, steering wheels, and trim pads. Working with active supplemental restraint systems carries inherent risks. Always disconnect the power supply and observe the required wait times before handling any airbag components to prevent accidental deployment or personal injury.

Beyond safety networks, the documentation breaks down starting and charging architectures. It provides factory operational parameters for AD230 and AD237 generators, highlighting bench testing limits and harness repair guidelines for high-amperage lines. You will also find clear, step-by-step documentation for crucial computer relearn cycles. This includes idle position learning, crankshaft position sensor variation, and the complete Pass-Key III auto-learn sequences.

Critical Factory Specifications

Accurate data ensures every component is properly secured and tested. The reference sets seat anchor bolts at 22 ft-lbs (30 N.m) and instrument panel upper trim pads at a precise 18 inch-lbs (2 N.m). Generator mounting bolts require 37 ft-lbs (50 N.m), while SDM fasteners must be tightened to 80 inch-lbs (9 N.m). Normal charging system voltage is documented to operate between 10.5 and 16.2 volts.
