ELECTRONIC TECHNICIAN (ET) TROUBLESHOOTING - Continued
Engine Timing Sensor Calibrate.
This procedure is required if a 261-E-13 Engine Timing Calibration code is active.
Also use this procedure if any of the following conditions exist:
The ECM has been replaced.
The Engine Timing sensors have been replaced.
The front engine gear group has been serviced.
The following tools are required:
Engine timing is not calibrated.
On EMCP, set ENGINE CONTROL switch to OFF/RESET. Set Battery
Disconnect Switch to OFF. Set DEAD CRANK SWITCH to OFF.
Remove timing calibration plug from either side of the flywheel housing. Refer to
Figure 10. The starter side of the engine is the easiest to access.
Use a flashlight to examine the flywheel through the timing calibration port where
the timing calibration plug was removed. Ensure that the timing pin hole that is
machined into the flywheel is not aligned with the timing calibration port (hole).
Refer to Figure 10. If necessary, rotate the crankshaft in order to cause the
misalignment of the holes.
Install the 7X-1171 transducer adapter into the timing calibration port hole.
