ELECTRONIC TECHNICIAN (ET) TROUBLESHOOTING - Continued
CORRECTIVE ACTION - Continued
NOTE
If the engine will not start, monitor the engine rpm on the Cat ET while the engine is being
cranked. The Cat ET may need to be powered from another battery while the engine is being
cranked.
STEP 5.
Wait at least 30 seconds for activation of the diagnostic codes. Look for these
codes on the Cat ET:
190-E-02
190-E-11
342-E-02
342-E-11
a. If code 190-E-02 is active, refer to WP 0009, SYMPTOM 25, CID 190-E-02.
b. If code 342-E-02 is active, refer to WP 0009, SYMPTOM 39, 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 sensor
(Figure 3).
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 assemblies (Figure 3) without removing the
sensor assemblies from the engine. Flanges of crankshaft timing sensor
(Figure 3, Item 1) and camshaft timing sensor (Figure 3, Item 2) must be
flush against engine in order to ensure proper operation.
c.
Inspect brackets (Figure 3, Item 3). Verify that the brackets securely hold the
flanges of the sensors flush against the engine. Verify that the brackets are
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.
NOTE
The bracket cannot be replaced separately.
d. Disconnect connector ENG P401 from the crankshaft engine timing (bottom)
sensor. Disconnect connector ENG P402 from the camshaft engine timing
(top) sensor. Remove bolt (Figure 5, Item 4) and washer (Figure 5, Item 5)
and remove the sensor assembly (Figure 5, Item 1 or Item 2) from the
engine.
