SPEEDOMETER GENERAL Ã The speedometer system is an electrical type that uses electric signals from the ABS or vehicle dynamics control (VDC) control module. Ã Since the system does not use mechanical components such as rotating cable, there are no opportunities of occurring such problems as meter needle vibration and cable disconnection. Also, it does not constitute any means of mechanical noise transmission. Ã The odometer and trip meter readings appear on a liquid crystal display (LCD). Ã At the trip meter display, the illumination level and the following trouble information (abnormality of various control modules, communication system, vehicle speed signals, etc.) are shown in addition to the trip meter reading.

CAN=Cotroller area network. Scan for additional codes and check wires between spped sensor at transmission to PCM. Check fuses as well. Can be wiring or bad TCM or body integrated unit. I sent a PDF via email for the tech...Make sure to scan for additional codes, Er HC only points to a communcation problem any module or ECM can cause it.
