Trouble Code Access
- Engine must be at normal operating temperature. Using jumper wire, ground Green, 1-pin check connector. On MPV, connector is located at left front corner of engine compartment. (Scheme 113) On B2600i, check connector is on right side fenderwell, near fuel filter and Green, 6-pin self-diagnostic connector. (Scheme 114) NOTE: ECU constantly checks for malfunction of input devices. However, ECU only checks output devices for 3-second period after ignition is turned on and Green check connector is grounded.
- Turn ignition switch to ON position. The codes may be read by counting number of pulses of Malfunction Indicator Light (MIL). MIL is located under the engine symbol marked CHECK, in center of instrument cluster.
- The code will be repeated, or other codes will be flashed if more than one is stored. (Scheme 115) If more than one code is stored, codes will be displayed in order of lowest to highest. See TROUBLE CODE IDENTIFICATION chart for diagnostic procedure.
