Causes

Faulty right rear sidemarker plate (LED module or lens/plate assembly)
Open or shorted wiring in sidemarker circuit
Corroded or damaged connector at sidemarker or chassis ground
Poor ground or intermittent connection
Body control module (BCM) output or software fault
Water ingress or corrosion in the sidemarker assembly or wiring harness

Symptoms

Right rear sidemarker not illuminating or flickering
Instrument cluster or vehicle messages about lamp failure
Intermittent operation of right rear sidemarker
Possible stored or active B1119 fault with related lighting behavior

What to check

Visually inspect right rear sidemarker plate for damage, corrosion, or water ingress
Check connector at sidemarker for corrosion, bent pins, or loose fit
Operate parking lights and observe right rear sidemarker response
Scan BCM for B1119 and any related codes; note freeze frame data
Measure supply voltage and ground at the sidemarker connector with lights on
Check for continuity between BCM output and sidemarker connector

Signal parameters

Supply voltage at sidemarker with lights ON: ~12V (battery voltage under load)
Ground continuity: near 0 ohms from sidemarker ground to chassis
Module output voltage or PWM signal from BCM (if applicable) when lights ON
Current draw of sidemarker assembly (LEDs typically low current; compare left vs right)
Resistance of sidemarker lamp/plate assembly (in-circuit or disconnected)

Diagnostic algorithm

Read and record DTCs and freeze-frame data with a capable diagnostic scanner; note whether fault is active or history.
Visually inspect the right rear sidemarker assembly, lens, and connector for damage, corrosion, or moisture. Repair or replace as needed.
With socket disconnected, measure resistance of the sidemarker lamp/plate assembly; compare to known-good or the left side. Replace assembly if open or out of specification.
Reconnect and measure voltage at the sidemarker connector while parking lights are ON. Verify proper supply voltage and good ground.
If voltage is absent, back-probe wiring toward the BCM to find open/short. Repair damaged wiring or connectors and re-test.
If supply and ground are good but lamp does not light, check BCM output using oscilloscope or scanner capable of monitoring output/PWM signals. If BCM output is absent or faulty, inspect BCM connector and fuses/relays.
After repairs, clear codes and retest operation over a drive or lamp cycles to confirm fault does not return.
If intermittent or unexplained failures persist, consider replacing the sidemarker plate assembly first (common failure point on LED units) before module replacement; consult manufacturer service info for BCM replacement procedures.

Likely causes

Corroded connector at right rear sidemarker plate
Open/short in wiring between BCM and sidemarker
Failed LED plate (common on LED-type sidemarkers)

Fault status

⚠️ Status

Right rear sidemarker plate circuit fault detected. Could be lamp/module failure, wiring/connector fault, or body module output/communication issue.
