Causes
- Damaged wiring insulation contacting chassis or ground
- Shorted or damaged memory switch (internal short)
- Corroded or loose connector pins causing unintended ground
- Water ingress in switch or connector
- Faulty body control module / memory module (less common)
- Aftermarket equipment or recent repairs damaging the harness
Symptoms
- Memory set/recall function inoperative or intermittent
- Stored memory positions not accepted or recalled
- One or more related switches produce no response
- DTC B1530 stored; possible related body module warnings
- Erratic behavior of memory-related actuators
What to check
- Read and record all stored codes and freeze-frame data with a scanner
- Visually inspect switch, harness, and connectors for damage or corrosion
- Wiggle test switch and harness while observing live data or DTC status
- Backprobe signal wire at the switch and at the receiving module to compare voltages
- Measure continuity between the signal wire and chassis ground with ignition OFF
- Disconnect the memory switch and see if the code clears or if symptoms change
Signal parameters
- Ignition ON, switch not actuated: signal circuit expected to be pulled up (approx. 5–12 V depending on design)
- When switch intentionally actuated (if it’s a switch-to-ground design): signal should drop to ~0 V
- With switch disconnected: resistance between signal wire and chassis ground should be very high (open/infinite)
- If short-to-ground present: measured voltage on signal wire will be ~0 V and continuity to ground will be near 0 Ω
Diagnostic algorithm
- Verify DTC B1530 with an OBD scanner and note any related/body codes; clear codes and attempt to reproduce to confirm persistence.
- Locate memory-setting switch, control module, and obtain the wiring diagram/pinout for the circuit.
- Visually inspect switch, connectors, and wiring along the entire harness route for chafing, pin damage, corrosion or water ingress.
- With ignition ON, backprobe the signal wire at the switch connector and at the module connector. Compare voltages to expected values (see signal_params).
- With ignition OFF, measure resistance/continuity between the signal wire and chassis ground. A near-zero reading confirms a short to ground.
- Disconnect the switch. If the DTC clears and the short condition goes away, suspect the switch assembly and replace or repair it. If code remains, continue tracing the harness.
- Isolate the short by unplugging intermediate connectors and retesting continuity to ground section-by-section until the faulted segment is found.
- Repair damaged wiring (insulation repair, splice, or harness replacement) or replace the faulty switch/connector as required. Use dielectric grease on connectors after repair.
- After repair, erase codes, perform functional test of memory settings, and road/test to confirm repair and absence of code return.
Likely causes
- Frayed harness where it contacts a metal edge causing a direct short to ground
- Switch internal failure shorting signal to ground
- Connector pin pushed out or bent and touching ground
- Moisture/corrosion bridging the signal to ground
Fault status
Status
Memory setting switch circuit short to ground — memory function may be disabled or unreliable.
Repair difficulty: Medium
Diagnostic time: 0.5-2.0 hours
