id0903d5807600

3	ABS warning light illuminates
POSSIBLE CAUSE	•  DSC/RSC HU/CM malfunction •  Instrument cluster malfunction •  Connector or pin malfunction •  Short circuit in wiring harness between CAN-L, CAN-H and ground •  Open circuit in CAN wiring harness (CAN-L, CAN-H) •  CAN wiring harness (CAN-L, CAN-H) short each other

Diagnostic procedure

STEP	INSPECTION		ACTION
1	•  Start the engine. •  Does the ABS warning light turn off?	Yes	Troubleshooting completed.
		No	Go to the next step.
2	•  Inspect the DTC for the instrument cluster ON-BOARD DIAGNOSTIC SYSTEM. •  Has DTC U2064 been recorded in memory?	Yes	Inspect the DTC for the DSC/RSC HU/CM. (See ON-BOARD DIAGNOSIS [DSC/RSC].)
		No	Go to the next step.
3	•  Disconnect the negative battery cable. •  Measure the resistance between the DLC-2 terminals F and E. •  Is the resistance below 60 ohms?	Yes	Go to the next step.
		No	Go to Step 5.
4	•  Inspect the DLC-2 terminals F and E for short to power supply or ground. •  Is there any malfunction?	Yes	Inspect the wiring harness and CAN system-related module. Repair or replace the malfunctioning part.
		No	Replace the instrument cluster.
5	•  Turn the ignition switch to the OFF position. •  Inspect the instrument cluster connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion). •  Are the terminals normal?	Yes	Go to the next step.
		No	Repair or replace the terminal.
6	•  Disconnect the negative battery cable. •  Measure the resistance between the instrument cluster connector terminals 1W and 1X. •  Is the resistance 114—126 ohms?	Yes	Inspect the wiring harness and CAN system-related module. Repair or replace the malfunctioning part.
		No	Replace the instrument cluster.
