Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Instrument Cluster
The instrument cluster displays a variety of information. It is an analog face cluster with a digital odometer. The instrument cluster is on both the medium speed CAN and the high speed CAN. If 1 of the 2 bus wires becomes shorted to ground or voltage, communications of the CAN may not be possible. If there is an open in the network, communications may continue between some modules depending upon the location of the open circuit. Check the high speed CAN circuits 1908 (WH) and 1909 (BK) between the instrument cluster C220 and the DLC C251. Check the medium speed CAN circuits 1847 (WH/OG) and 1848 (PK/OG) between the instrument cluster C220 and the DLC C251. Total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the CAN, damage to the DLC C251, damage to the instrument cluster C220, or a problem in the in-line connector.
