the passenger compartment; at the lower edge of (2) Turn the ignition switch on and access the “Read Fault” screen. (3) Record all the DTC’s and “freeze frame” infor- mation shown on the DRB scan tool. (4) To erase DTC’s, use the “Erase Trouble Code” data screen on the DRB scan tool. Do not erase any DIAGNOSTIC TROUBLE CODE DESCRIPTIONS (M) Check Engine Lamp (MIL) will illuminate during engine operation if this Diagnostic Trouble Code was recorded. (G) Generator Lamp Illuminated GENERIC SCAN TOOL CODE DRB SCAN TOOL DISPLAY DESCRIPTION OF DIAGNOSTIC TROUBLE CODE P0106 (M) Barometric Pressure Out of Range MAP sensor input voltage out of an acceptable range detected during reading of barometric pressure at key-on.
