ALFA ROMEO B — Body

Memory 1 switch circuit open

Brand: ALFA ROMEO
Type: B — Body
Views: UK: 24 EN: 29 RU: 21
AI status
Completed
ready
Completed 100%
Page language: EN

Causes

  • Faulty Memory 1 switch (mechanical/electrical failure)
  • Open or broken wiring between switch and control module
  • Poor or corroded connector at switch or control module
  • Blown fuse or power supply interruption to switch circuit
  • Faulty ground or grounding point
  • Faulty BCM / control module input

Symptoms

  • Memory 1 recall/store function does not operate
  • No LED or indicator when Memory 1 button is pressed
  • Unable to save or recall seat/mirror/steering positions for memory slot 1
  • Fault stored in vehicle diagnostic memory (B1532)
  • Intermittent operation of memory functions

What to check

  • Read all stored codes and freeze frame data with a diagnostic scanner; clear and re-scan.
  • Visually inspect Memory 1 switch, wiring harness, and connectors for damage, corrosion, or water ingress.
  • Verify fuses and power supply feeding the switch circuit.
  • Check connector pins for bent, pushed-out, or corroded terminals.
  • Perform a wiggle test on the harness while operating the switch to look for intermittent faults.
  • Measure continuity between the switch terminal and the BCM input pin; check for open circuit.

Signal parameters

  • Signal type: low-voltage digital/switch input to the BCM
  • Typical behavior: switch changes logic state when pressed (expected voltage change between supply and ground) — exact voltage depends on vehicle design
  • Closed-switch continuity: near 0 ohms between switch terminals when actuated
  • Open-switch: high resistance/OL (no continuity)
  • Measured at switch connector and BCM pin to confirm circuit integrity

Diagnostic algorithm

  1. Verify the code: scan the vehicle and confirm B1532 is current or stored; check for related codes.
  2. Inspect switch and wiring: visually inspect the Memory 1 switch, harness, connectors, and nearby components for damage or contamination.
  3. Check power and fuse: verify the fuse and supply voltage to the switch circuit with ignition on.
  4. Test switch operation at the connector: backprobe the switch connector and observe voltage/continuity while operating the switch. If the switch does not change state, suspect the switch.
  5. Continuity to control module: with battery disconnected, measure continuity/resistance between the switch terminal and the BCM/input module pin. An open indicates wiring/connector fault.
  6. Repair wiring/connectors: repair any damaged wires, clean or replace corroded connectors, and secure pin connections.
  7. Replace switch if wiring and supply are good but switch does not change state or shows high resistance when actuated.
  8. If circuit and switch test good, test or reflash the BCM or replace if confirmed faulty by manufacturer procedures.
  9. Clear codes and verify repair: erase codes, cycle ignition, and verify that the memory 1 function works and B1532 does not return.

Likely causes

  • Disconnected or corroded connector at the Memory 1 switch
  • Open/broken wire in switch harness (pinched, chafed, broken)
  • Failed Memory 1 switch assembly
  • Poor ground at switch or module
  • Intermittent connector contact or contamination

Fault status

⚠️ Status
Memory 1 switch circuit open — control module does not detect the Memory 1 switch signal. Inspect switch, wiring, connectors, power and grounds.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2.0 hours
