Causes

  • Blown fuse for washer pump/actuator circuit
  • Open or short in wiring harness to LIDAR washer actuator A
  • Corroded, loose or damaged connector at actuator or body control module (BCM)
  • Failed washer actuator (pump/motor/solenoid)
  • BCM or module output driver fault
  • Water intrusion or mechanical seizure in actuator

Symptoms

  • LIDAR washer does not operate when commanded
  • Intermittent washer operation or only works sometimes
  • Washer runs continuously or cannot be turned off
  • Warning or fault message on instrument cluster relating to LIDAR cleaning
  • Unusual noise from washer pump or no noise when commanded

What to check

  • Check for stored freeze-frame and related codes in BCM and sensor modules
  • Visual inspection: harness, connectors, grommets and actuator for damage or corrosion
  • Verify fuse(s) for washer/actuator circuit are intact and correctly rated
  • Operate washer while monitoring for expected actuator response (noise, flow)
  • Probe for power and ground at actuator connector with command active
  • Measure actuator resistance and compare to specification or bench-test with known good 12V supply

Signal parameters

  • Key ON (not running): 0 V to battery voltage at actuator power pin depending on switch/relay state
  • When commanded ON: actuator power pin ~12 V (or PWM depending on vehicle) — typically 11–14 V
  • Ground continuity: near 0 Ω between actuator ground pin and vehicle chassis ground
  • Actuator coil/motor resistance: typical pump motors vary; expect low ohms (few Ω to tens of Ω). Compare to service data
  • Command signal (if PWM): duty cycle 0–100% and frequency as specified by OEM (often a few hundred Hz)

Diagnostic algorithm

  1. Read and record DTC B0106 and any related codes from all modules. Check freeze frame and re-create condition if needed.
  2. Perform visual inspection of washer actuator A, tubing and wiring. Look for damage, corrosion, pin push-out or water intrusion.
  3. Verify fuses and relays for washer/cleaning system. Replace any blown fuse and re-test.
  4. Attempt to activate the LIDAR washer from the switch or diagnostic tester. Note audible pump noise or lack of movement.
  5. Backprobe actuator connector while commanding: check for battery voltage on power feed and good ground. If no voltage but switch/BCM commanded, trace upstream (relay, fuse, BCM output).
  6. If voltage present but actuator does not run, disconnect actuator and bench-test with direct 12V (be cautious; observe current draw). If actuator fails bench test, replace actuator.
  7. If actuator works on bench but not in vehicle and power/ground present only when commanded, measure current draw in-circuit. Excessive draw indicates mechanical binding or fluid blockage; open circuit indicates internal actuator fault.
  8. If no power from BCM output, check for communication errors, scan for BCM-related codes, and inspect/repair wiring or replace BCM only after confirming wiring and grounds are good.
  9. Repair or replace damaged connectors, wiring, fuses, relays or actuator as indicated. Clear codes and validate repair by cycling the washer and rechecking for codes.

Likely causes

  • Failed washer actuator (pump motor seized or burned)
  • Open/shorted harness between BCM and actuator
  • Connector corrosion or pin damage at actuator
  • Blown/weak fuse or fusible link
  • BCM output driver failed or internal module fault

Fault status

⚠️ Status
LIDAR washer actuator A circuit fault — actuator failed or circuit abnormal (power, ground, wiring or module).
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2.0 hours
