Causes
- Blown bulb or failed LED unit
- Blown fuse or tripped circuit protection
- Open, corroded or loose connector at the right static lamp
- Broken or chafed wire in the harness (open or short to ground/12V)
- Poor ground connection at lamp or body earth
- Corrosion or water ingress at lamp housing or connector
Symptoms
- Right static/parking/position lamp does not illuminate
- Intermittent illumination or flicker of the right static lamp
- Instrument cluster or message centre lamp fault/warning displayed
- Related lighting functions operate normally on the left side
- Possible multiple lighting DTCs if a module output is shorted
What to check
- Read stored and pending DTCs and any related body network codes using a capable scan tool
- Visually inspect the right static lamp assembly, socket and connector for corrosion, water, damage or loose pins
- Inspect wiring harness along route for damage, repairs or pinched sections
- Check relevant fuses and fuseholder contacts
- Remove bulb or lamp module and inspect/measure filament or LED unit resistance
- With lamp connector disconnected, check for corrosion and bent pins
Signal parameters
- Expected supply voltage at lamp connector: battery voltage (~11.5–14.5 V) when lights are on (no excessive voltage drop)
- Typical incandescent parking lamp resistance: ~5–10 Ω (varies by lamp wattage) — LED assemblies will show much higher/complex resistance; check manufacturer specs
- Current draw for incandescent parking lamp: roughly 0.3–1.0 A (depends on lamp wattage); LED much lower and may require CAN/driver checks
- Acceptable voltage drop between module feed and lamp connector:
- Ground continuity: near 0 Ω between lamp ground pin and vehicle chassis ground
- If lamp driver is PWM, frequency may be present — use an oscilloscope or diagnostic tool to view duty cycle and frequency
Diagnostic algorithm
- Connect a capable scan tool. Read and record DTC B13CC and any related codes. Note freeze-frame/live-data.
- Perform a visual inspection of the right static lamp assembly, socket and adjacent wiring. Check for moisture, corrosion or physical damage.
- Check fuses/circuit breakers for the lighting circuit. Replace/test fuse and fuseholder if suspect.
- Remove the lamp/bulb and inspect the lamp element. Test lamp continuity/resistance. Replace lamp if open or visibly failed.
- With connector disconnected, measure supply voltage at the lamp feed pin with lights ON. If battery voltage is present, measure ground continuity at the ground pin.
- If no supply voltage, trace back to the fuse and BCM output. Check for voltage at BCM connector or intermediate splice. Repair/open circuit as found.
- If supply voltage present but lamp does not illuminate, apply a fused 12V bench supply to the lamp connector to verify lamp/LED operation and isolate wiring.
- If supply is low or intermittent, perform wiggle test and probe wiring for intermittent shorts/opens. Repair harness damage and secure routing.
- If a short to ground or to 12V is suspected, isolate circuit sections and measure resistance to identify short location. Repair or replace wiring as required.
- If wiring and lamp check good, test/replace the body control module/lighting driver or its connector only after confirming a good wiring harness and verifying the module output is faulty.
- Clear codes and re-test operation. Confirm repair by road test and checking for reappearance of the code.
Likely causes
- Blown lamp filament or failed LED assembly
- Corroded/loose connector pins at the lamp socket
- Broken conductor in the right front/rear harness (pinched or rubbed through)
- Failed ground/earth strap at lamp mounting point
- Open fuse or poor fuse contact
- Faulty lamp output transistor inside BCM or damaged connector at module
Fault status
Status
Right static lighting lamp — electrical supply fault detected (circuit supply voltage out of range, open or short). Lamp may be inoperative or intermittent.
Repair difficulty: Medium
Diagnostic time: 0.5-2.0 hours
