Check engine light on? Do this to retrieve the two digit code(s) and report back. Using Malfunction Indicator Light (MIL) 1. Ensure battery is fully charged. Turn ignition on and note operation of MIL. The MIL is located on instrument panel. When ignition is first turned on, MIL should come on to verify bulb and circuit operation, and then go off. 2. Turn ignition on, off, on, off and on within 5 seconds. Record 2-digit Diagnostic Trouble Codes (DTCs) as displayed by flashing MIL. 3. For example, DTC 24 will be displayed by 2 flashes, short pause, and then 4 flashes. A short pause will exist between first and second digits on DTC. If more than one DTC is stored, after first DTC is displayed, there will be a longer pause and then another stored DTC will be displayed. 4. Once all DTCs are recorded, proceed to retrieving DTCs using scan tool to ensure all DTCs are obtained. See USING SCAN TOOL. NOTE: If MIL does not come on and then go off, bulb circuit may be defective, or problem area may exist on CCD Bus between Powertrain Control Module (PCM) and instrument cluster. If problem exists with CCD Bus, this problem may be displayed when using scan tool to retrieve DTCs.

Normally if the lights are dimming, it indicates a charging system fault, and a code 41 would flash, try the test anyway to see if it's stored in memory.

I would start by checking all grounds and ground straps you can find. Also negative battery cable ground at the block. PCM ground too.
