This is the first thing we need to do, then post any codes that flash on MIL.
Using Malfunction Indicator Light (MIL) 1. Ensure battery is fully charged. Turn ignition on and note operation of MIL. The MIL is located in message center above instrument panel. When ignition is first turned on, MIL should come on and remain on for 3 seconds to verify bulb and circuit operation and then go off. 2. Attempt to start engine. Turn ignition off. Without starting engine, 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 for 3 seconds and then go off, bulb circuit may be defective or problem area may exist on wire between between Powertrain Control Module (PCM) and instrument cluster.
