TROUBLESHOOTING PROCEDURES
CAUTION
All active fault codes must be investigated prior to replacing the engine Electronic Control Module
(ECM). Failure to comply may cause damage to equipment.
NOTE
Some sensors share harness wiring. Some malfunctions in certain sensors or in the engine ECM
may cause false errors to display because of this shared wiring. For this malfunction (SPN# 102,
FMI# 4), the harness wiring is shared by the intake manifold pressure/temperature sensor, the
camshaft position sensor, the water-in-fuel sensor, and the fuel rail pressure sensor.

MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
1. Multiple fault codes.
1. Install fuse box (WP 0277, Vol
2).
2. Connect battery cables (WP
0357, Vol 2).
