Trouble Code Access
- Engine must be at normal operating temperature. Using jumper wire, ground Green 1-pin check connector. On B2600i, the check connector is on the right side fenderwell, near the fuel filter and the Green, 6-pin self-diagnostic connector.NOTE: ECU constantly checks for malfunction of input devices. However, ECU only checks output devices for 3-second period after igntion is turned on and Green check connector is grounded.
- Turn the ignition to "ON" position. The codes may be read by counting the number of pulses of the Malfunction Indicator Light (MIL). MIL is under the engine symbol marked "CHECK" in the center of the instrument cluster.
- The code will repeat or other codes will flash, if more than one is stored. See Fig 1 .
- If there is more than one code stored, the LOWEST numbered code will be displayed first. Remaining codes are displayed in order from lowest to highest. Refer to appropriate TROUBLE CODE IDENTIFICATION chart for diagnostic procedure.
NOTE:
In addition to displaying computer system malfunction codes (codes only on California models), the CHECK light acts as an emission maintenance warning.
