Stoplamps (G830846)

DIAGNOSIS AND TESTING
Overview

For information on the description and operation of the system, refer to section 417-01 - Exterior Lighting of the workshop manual. Note that the stoplamps will be activated automatically under certain conditions when the ride and handling optimization function is used, refer to section 204-06 - Ride and Handling Optimization of the workshop manual.

Inspection and Verification
  1. Verify the customer concern.
  1. Visually inspect for obvious electrical faults.

Visual Inspection Chart

Mechanical Electrical
  • Stoplamp condition and installation
  • Bulbs and installation
  • Bulb holders and installation
  • Stoplamp switch condition and installation
  • Fuses
    • Battery junction box (BJB) - link 16E
    • BJB - link 11E
    • Central junction box (CJB) - Fuse 15P
    • CJB - fuse 66P
  • Wiring harness
  • Loose or corroded connector(s)
  • Hill descent relay
  • Battery junction box (BJB)
  • Central junction box (CJB)
  • ABS control module
  • Controller area network (CAN) circuits
  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving onto the symptom chart or DTC index.
      • Because the DTCs are stored in more than one module, a complete vehicle read is recommended.
      • Make sure that all DTCs are cleared following rectification
Symptom Chart
SymptomPossible causesAction
Stoplamp(s) inoperative
  • Bulb failure
  • LED lamp failure
  • Fuse(s) blown
  • Circuit fault
  • Stoplamp switch fault
Check the bulb, LED lamp and fuse condition (see visual inspection). Check the stoplamp circuits. Check the stoplamp switch function. Refer to the electrical guides. Check for DTCs indicating a stoplamp circuit fault.
Stoplamp(s) dim
  • Incorrect bulb rating
  • Circuit fault
Check the bulb condition and rating. Check the stoplamp circuits. Refer to the electrical guides.
Stoplamp(s) stuck on
  • Stoplamp switch fault
  • Circuit fault
  • Hill descent relay circuit fault
Check the stoplamp switch function. Check the stoplamp circuits. Refer to the electrical guides. Check for DTCs indicating a stoplamp circuit fault
DTC index
NOTE:

Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system).
