ELECTRONIC TECHNICIAN (ET) TROUBLESHOOTING - Continued
CORRECTIVE ACTION - Continued
NOTE
If the engine will not start, engine rpm can be monitored on the Cat ET while the engine is being
cranked by using the Status Tool.
STEP 5.
Wait at least 30 seconds for activation of the diagnostic codes. Look for these
codes on the Cat ET:
190-E-02 Loss of primary (top) engine timing signal
190-E-11 Primary (top) engine timing sensor mechanical failure
342-E-02 Loss of secondary (bottom) engine timing signal
342-E-11 Secondary (bottom) engine timing sensor mechanical failure
a. If code 190-E-02 is active, refer to WP 0009, SYMPTOM 28, CID 190-E-02.
b. If code 342-E-02 is active, refer to WP 0009, SYMPTOM 42, CID 342-E-02.
c.
If codes 190-E-11 and/or 342-E-11 are active, proceed to STEP 6.
NOTE
If the engine will not start and the Cat ET displayed 0 rpm during cranking, select No Engine rpm.
STEP 6.
If engine rpm is not indicated on the Cat ET, check the installation of the sensors
(Figure 5).
a. On EMCP set ENGINE CONTROL switch to OFF/RESET. Set Battery
Disconnect Switch to OFF. Set DEAD CRANK SWITCH to OFF.
b. Visually inspect the sensor assembly without removing the sensor assembly
from the engine. Flanges of sensors (Figure 5, Item 2) must be flush against
engine (Figure 5, Item 1) in order to ensure proper operation.
c.
Inspect bracket (Figure 5, Item 3). Verify that the bracket securely holds the
flanges of the sensors flush against the engine. Verify that the bracket is not
bent. If the bracket is bent or if an obstruction is preventing the sensor
assembly from being installed correctly, the engine will not start.
