Causes

Failed LED or LED module in exterior door handle
Open or short circuit in the door-handle lighting wiring harness or connector
Corroded/loose connector or pin at handle or at BCM/harness splice
Blown fuse or faulty lighting relay/power supply
Poor ground at handle or vehicle body ground point
Faulty BCM or body module output circuit

Symptoms

Exterior door handle illumination absent or intermittent
Door handle LED flickers or stays permanently on
Interior/exterior ambient lighting warning message or stored body module fault
Possible error or warning on instrument cluster / message centre
No change to door-handle lighting after switching vehicle lighting modes

What to check

Visual inspection of the affected door handle for damage, moisture or loose trim
Check related fuses and fusable links for the door-handle / exterior lighting circuit
Scan vehicle with a capable diagnostic tool for B1326 and any related codes (BCM and body network)
Inspect connectors at the door handle and at the door hinge/door jamb harness for corrosion, bent pins or water ingress
Confirm good battery voltage and engine/ignition on supply at the BCM and at the handle connector
Verify vehicle network (CAN) communication to the BCM with a scan tool

Signal parameters

Supply voltage to handle with ignition/lighting on: approx. 11–14 V expected
LED forward voltage (depending on color): typically ~2.0–3.5 V (single LED) — measured across LED terminals when driven
LED current: generally low (10–50 mA) — check current only if safe and by spec
Resistance between LED positive and ground with circuit disconnected: open/infinite may indicate failed LED; very low may indicate short
Continuity from BCM output to handle lamp connector: near 0 Ω to low ohms (allow for connector resistance)
CAN/BCM message: BCM should be present on network and able to report lamp status via diagnostic tool

Diagnostic algorithm

Retrieve and record all stored DTCs and freeze frame data with a diagnostic scanner; note any other related B or U codes
Perform a visual inspection of the affected handle assembly and adjacent wiring for physical damage, signs of moisture ingress, or loose mounting
Check fuses related to exterior/door lighting; replace any blown fuses and re-test
With ignition on, measure battery/supply voltage at the handle connector power pin; if no supply, trace back to fuse, relay or wiring
Check ground at the handle: measure voltage drop between handle ground and battery negative while illuminating circuit (should be very low); repair any high-resistance ground
Using an appropriate meter, check for continuity between the BCM output pin and the handle connector; if open, inspect/repair harness and door flex/hinge area
If power and ground are present at the handle but LED does not light, remove the handle lamp module and bench-test the LED (apply correct polarity and limited current per spec) to confirm LED condition
Inspect connector pins for corrosion or bent pins; clean contact surfaces and apply dielectric grease if required
If wiring and lamp module test good but fault remains, check BCM outputs and body network messages with manufacturer-level diagnostic tool; monitor live data for lamp control command and status
If BCM output is suspect and all wiring/LED checks are good, consider BCM replacement or module repair per manufacturer procedures (follow vehicle-specific programming and coding steps)
After any repair, clear codes and perform functional test of door-handle illumination across lighting modes and vehicle sleep/wake cycles; road/test cycle if required to ensure issue is resolved

Likely causes

Failed LED/LED module in the door handle
Open or damaged wiring or connector to the handle
Corroded connector or water ingress at the handle
Blown fuse or poor ground connection

Fault status

⚠️ Status

Exterior door handle LED — Circuit fault (open/short/intermittent) reported by body control module
