Circuit/System Description

The instrument cluster displays the engine coolant temperature, fuel level, vehicle speed and the engine speed based on the information from the engine control module (ECM). The ECM sends information via a High Speed CAN-Bus signal to the body control module (BCM). The BCM then sends the information via a Low Speed CAN-Bus signal to the instrument cluster to display the engine coolant temperature, fuel level, the engine speed, the vehicle speed and the distance travelled, either in kilometers or miles, based on the vehicle requirements.

Circuit/System Verification

1. Vehicle in Service Mode, perform the Instrument Cluster Gauge Sweep test with the scan tool, verify that the instrument cluster performs a screen test sequence.

Note:
Since there are no gauges, the instrument cluster will go through a screen test sequence instead of sweeping the gauges.

• If the instrument cluster does not perform the screen test sequence, replace the P16 instrument cluster.

2. Perform the Driver Information Center Segments test for each color, White, Blue, Green, Red, Black and Off with a scan tool, verify there are no stuck or dead pixels in any color.

• If there are any stuck or dead pixels in any color, replace the P16 instrument cluster.

Repair Instructions

Perform the Diagnostic Repair Verification Verification Tests after completing the diagnostic procedure.
