🚨 Diagnostic Profile
Vehicle Make: Chrysler
Fault Description: Cruise Direction Circuit High Volume. The cruise control direction input is reading a voltage or signal level above its expected range. This typically involves the steering wheel cruise control switch circuit or its wiring to the controlling module.
🚨 Repair Difficulty Tier
Tier: [Intermediate]
This repair requires scan tool capability, electrical circuit testing, and steering wheel and airbag system precautions.
🛠️ Resolution Steps
Step 1: Preliminary Inspection
- Verify battery voltage and charging system output are within specification (typically 12.4-12.6V key off, 13.5-14.7V running).
- Visually inspect the cruise control switch connector and steering column harness for corrosion, spread terminals, moisture, or chafing.
- Inspect the wiring path along the steering column for pinched or damaged insulation near the clockspring/airbag coil assembly and the lower steering column harness routing, as this is a common chafe point on Chrysler platforms.
- Check cruise-related fuses and relays at the Totally Integrated Power Module (TIPM) or under-hood/under-dash power distribution center, referencing the fuse diagram on the cover for the cruise control or steering control module circuit.
- Record freeze frame data and note the conditions present when the code set, including vehicle speed, switch position, and ambient temperature.
Step 2: Diagnostic Verification
- Retrieve the DTC with a compatible scan tool and confirm whether it is current or history.
- Monitor the cruise direction/resistance-based switch input parameter on a live data stream while actuating the cruise control switch through each position (On/Off, Set/Accel, Resume, Cancel) and confirm each position produces a distinct, stable value.
- Measure circuit voltage at the cruise control switch signal circuit using a digital multimeter with the key on and engine off, comparing the reading against factory service information reference values for each switch position, since these multiplexed switches typically operate on a stepped-resistance ladder network fed by a reference voltage (commonly 5V).
- Check for a short to voltage or high resistance using a digital multimeter at the steering wheel switch connector and the body control module or steering control module connector, back-probing to avoid damaging terminals.
- Verify ground integrity at the module ground circuit and the switch ground return path, ensuring resistance to ground is near zero ohms.
Step 3: Resolution & Reset Process
- Repair or replace the faulty cruise switch, clockspring, wiring, or connector per factory service information, ensuring proper terminal tension and connector seating.
- Disconnect the battery before servicing any airbag-related components (clockspring/steering column) and observe the required wait time of at least 2 minutes to allow airbag system capacitors to discharge.
- Clear all DTCs with the scan tool and perform a key cycle (key on for 10 seconds, then off).
- Road test the cruise control system to confirm set, resume, accel, and cancel functions operate correctly across varying speeds.
- Re-scan the system to verify the code does not return and confirm no airbag or steering-related faults were introduced during the repair.
📦 Parts, Labor, and Budget Estimates
Required Components/Software:
Steering wheel cruise control switch assembly (OEM or quality aftermarket equivalent), clockspring/airbag coil assembly if wiring damage is traced through the column, steering column wiring harness repair pigtail/connector kit if terminals or wiring are damaged, and a capable scan tool (factory-level such as a Chrysler-compatible diagnostic system, or a quality aftermarket bidirectional scanner) for DTC retrieval, live data monitoring, and post-repair verification. No module reprogramming is typically required for this fault unless the body control module or steering control module itself is replaced.
Average Component Price:
Cruise control switch assembly: approximately $60-$180 for the part depending on trim level and switch type. Clockspring/airbag coil assembly (only if required): approximately $90-$250 for the part. Wiring/connector repair kit: approximately $20-$60. Diagnostic scan fee at an independent shop or dealer: approximately $100-$180.
Estimated Labor Hours:
Diagnostic time (circuit testing and verification): 0.5-1.0 hour. Cruise control switch replacement: 0.3-0.7 hour. Clockspring/airbag coil replacement (if required): 1.0-1.8 hours due to steering wheel and airbag removal/reinstallation and safe-handling procedures. Total estimated shop time for diagnosis through repair typically ranges from 1.0 to 2.5 hours depending on root cause, billed at the shop’s standard labor rate.
