Causes

  • Blown fuse supplying adjustable pedal switch or accessory delay circuit
  • Open or short in wiring between adjustable pedal switch and control module (short to battery or ground)
  • Corroded, loose or damaged connector at the adjustable pedal switch or control module
  • Failed adjustable pedal switch (internal contact or sensor failure)
  • Faulty body control module (BCM) or pedal module software/firmware issue
  • Water ingress or physical damage to pedal assembly or harness

Symptoms

  • Adjustable pedal does not move or moves intermittently
  • Accessory delay feature (retained accessory power) not working correctly
  • DTC lamp or warning stored in body module
  • Intermittent operation of related accessories (radio, windows) when key off
  • Stored fault codes related to pedal or accessory circuits

What to check

  • Read fault memory with a Land Rover-capable scan tool; note freeze frame and occurrence count
  • Check battery voltage (should be ~12–14.5 V) and ground integrity before testing circuits
  • Visually inspect wiring and connectors at the adjustable pedal, footwell loom and BCM for corrosion, damage, or water ingress
  • Check fuses and fusible links for the adjustable pedal and accessory/BCM circuits
  • With ignition off and battery disconnected, wiggle harnesses while inspecting for intermittent faults

Signal parameters

  • Battery supply to circuit: ~11–14.5 V when key ON/engine running; 0 V when battery removed
  • Switch output (when closed): near ground depending on configuration (0–1 V) or pulled to supply voltage (approx. 5 V or battery voltage) depending on design — consult vehicle wiring/data
  • Open circuit: infinite resistance between switch contacts; closed circuit: near 0 Ω continuity
  • Typical module input logic threshold: low 3–4 V (depends on module — verify with factory data)
  • CAN/LIN messages: pedal position or switch state should be present on network when using scan tool (verify live data)

Diagnostic algorithm

  1. Connect dealer-level diagnostic tool, read and record B2358 and any related codes; note freeze-frame data and test values.
  2. Verify battery voltage and good chassis/engine/BCM grounds. Repair any low-voltage or poor-ground conditions.
  3. Inspect the adjustable pedal switch connector and wiring harness for damage, corrosion, or water; repair or protect damaged sections.
  4. Check fuses related to pedal/BCM/accessory delay; replace any blown fuses and retest.
  5. With connector unplugged, measure continuity between pedal switch terminals and BCM harness pins to check for open or short circuits. Expected: continuity when switch closed, high resistance/open when open (refer to wiring diagram).
  6. Backprobe switch connector with ignition ON and operate pedal adjustment while watching live data for switch state or voltage. Confirm the signal changes cleanly and matches expected voltage levels.
  7. If wiring and voltages are good but signal is invalid/intermittent, swap or bench-test the adjustable pedal switch per service manual procedures, or replace switch and retest.
  8. If fault remains after replacing switch and repairing wiring, check BCM/pedal module power, ground, and communication lines (CAN/LIN). Use scope to check for noise, shorted CAN lines or missing messages.
  9. If CAN or module faults are present, diagnose communications (shorts, terminations, multiple nodes) or consider module reflash/replacement following manufacturer procedures.
  10. Clear codes and perform functional test cycles (pedal adjust, accessory delay) and road / key-off tests to confirm repair.

Likely causes

  • Damaged wiring harness at pedal due to chafing or pedal travel
  • Corroded connector pins at pedal switch or BCM connector
  • Failed adjustable pedal switch contacts (sticking or intermittent)
  • Blown/incorrect fuse in accessory/BCM circuit
  • Poor ground connection for the pedal module or BCM
