the connector. Rectify as necessary. Clear the DTCs. Reconnect the
injector and start the engine. Allow to warm up to above 60°C (140°F) and
allow to idle (cylinder balance diagnosis is now active). If the DTC
resets, check for Cylinder leakage and rectify as necessary. Clear the
DTCs and recheck. Carry out a compression test only if the DTC resets. If
the above tests are all within range, install a new injector. |
