What it means

On a Saturn, P1560 means the control unit detected a cruise control request or operation while the transaxle was not reporting a drive gear position. The engine control module compares the cruise control status with the gear or range signal from the transaxle range switch and sets the code when the two do not agree. Exact logic and thresholds can vary by model, engine and transmission type.

Symptoms

  • Cruise control will not engage or drops out unexpectedly
  • Cruise control works only in certain gear selector positions
  • Malfunction indicator lamp or service lamp may be illuminated
  • Gear indicator on the dash may not match the selector position
  • Starting may be affected on some models if the range switch is faulty

Possible causes

  • Faulty or misadjusted transaxle range switch (park/neutral or gear position switch)likely
  • Damaged wiring or corroded connector in the range switch circuitlikely
  • Worn or stretched gear selector linkage or cable out of adjustmentpossible
  • Fault in the cruise control switch or brake switch circuit giving a false requestpossible
  • Internal transaxle fault affecting range or gear position signalsrare
  • Fault within the engine control module or transmission control modulerare

How to diagnose

  1. Read all stored and pending codes and record the freeze frame data, noting whether other transmission or cruise codes are present
  2. Check whether the dash gear indicator and the scan data for gear or range position match the selector position in every position
  3. Check the selector linkage or cable for wear, looseness and correct adjustment
  4. Inspect the range switch wiring and connector for damage, water ingress, corrosion and bent pins
  5. Check the brake switch and cruise control switch operation and signals in live data
  6. Test the range switch circuit for correct voltage, ground and continuity against the model-specific wiring diagram
  7. Check the range switch signal states in each selector position against manufacturer specifications
  8. Check for relevant technical service bulletins for the specific model and transmission

How to fix

  • Adjust or replace the transaxle range switch as required
  • Repair or replace damaged wiring and clean or replace corroded connectors
  • Adjust or replace worn selector linkage or cable
  • Replace a faulty cruise control or brake switch
  • Repair the internal transaxle fault once confirmed by diagnosis
  • Replace or reprogram a control module only after all wiring and switch faults are ruled out and a fault is confirmed

Can I keep driving?

Low severity

The car can normally be driven, with cruise control unavailable. If the gear indicator is wrong or starting is affected, have it checked soon, as the range switch fault may worsen.
