This document is page SD925-1, "Turn & Hazard Lamps (1)," a factory-style wiring diagram covering the turn signal and hazard lamp circuits. It shows power feeds from the Smart Junction Box: a HAZARD 15A fuse (hot at all times) and a MODULE2 7.5A fuse (hot in ON or START), plus the Flasher Sound Relay and IPS Control Module with B-CAN Low/High lines. Circuits route through connectors I/P-A, I/P-C, I/P-D, M02-A/B/C, M11, M48-L, M06-A/M07-A, JM01, and JM04 to the BCM (turn signal switch signals LH/RH, hazard switch signal, battery power, B-CAN, ground), the Multi-Function Switch (turn signal switch LH/RH), the Hazard Switch on the A/C Control Module (manual and auto A/C variants), and the Instrument Cluster (turn indicators, LED drive IC, MICOM, B-CAN transceiver). Wire gauges/colors such as 0.5R/B, 0.22O, 0.22Y, 0.22W, 0.3L, 0.3R, 0.3P, and 1.25B are labeled, and cross-references point to Power Distribution (SD110-7/8/9), Passenger Compartment Fuse Details (SD120-4), Ground Distribution (SD130-2), Data Link Details (SD200-3), and ground point GM02. A reader can trace turn/hazard circuit wiring, fuse ratings, connector pin numbers, and module interconnections.

Frequently asked questions

What fuse powers the hazard lamps circuit?
The HAZARD 15A fuse in the Smart Junction Box, on a HOT AT ALL TIMES feed, powers the hazard circuit; a MODULE2 7.5A fuse (HOT IN ON OR START) also feeds the circuit.
Where is the hazard switch located in this circuit?
The hazard switch (OFF/ON) is part of the A/C Control Module (connector M06-A for manual A/C or M07-A for auto A/C, pins 20 and 39), shown as PHOTO 120.
Which connector pins on the BCM carry the turn signal switch signals?
Pins 11 (LH, wire 0.22O) and 2 (RH, wire 0.22Y) of connector M02-B on the BCM carry the turn signal switch signals from the multi-function switch via connector M48-L.
What produces the flasher clicking sound?
A Flasher Sound Relay inside the Smart Junction Box (pins 30, 85, 86) provides the operation sound, controlled by the IPS Control Module via Flasher Sound Relay Control.
How do the instrument cluster turn indicators get their signal?
The instrument cluster (connector M11) receives 0.3P power at pin 29 and communicates over B-CAN High (pin 34, 0.3R) and Low (pin 35, 0.3L) through a B-CAN transceiver, MICOM, and LED drive IC that light the TURN LEFT and TURN LIGHT indicators.
