Confirmed Fix:
Replaced Mass Air Flow (MAF) Sensor
 
Problem Description:
Vehicle has trouble codes P0102 in the ECM and C1503 and C1611 in the ABS system. The Mass Air Flow (MAF) sensor was bad as it read 0v on the signal wire. The C1503 was from the vehicle owner holding the switch trying to turn the ESC light off. The C1611 was caused by the lack of a load signal from the ECM. The trouble tree does not indicate that the MAF sensor is something that can cause this. The MAF sensor was replaced and the vehicle is repaired.

Confirmed Fix:
Replaced Differential Intake Air Control Valve (DISA) and Replaced Crankcase Ventilation Hose(s)
 
Problem Description:
After replacement of a broken flap for the Differential Intake Air Control Valve (DISA), trouble codes P0171, P0174, P1083 and P1085 were found. Not only did the flap snap from the pivot but it was allowing unmetered air into the intake manifold. Found that the crankcase ventilation hose (from the dip stick tube) had a crack in it near the intake connection. Replaced the crankcase hose and the problem has been repaired.

Confirmed Fix:
Repaired Starter Wiring
 
Problem Description:
The engine will not crank over. Replaced the fuse for the starter and it immediately blew. Found no shorts in the starter circuit. The wiring diagram shows that the crank fuse feeds the 4WD module and the harness goes behind the ABS module bracket. Found the wiring chaffed on the bracket. Every time the engine started to crank the harness chaffed against the bracket and blew the fuse. Repaired the wiring harness and the vehicle is fixed.

Confirmed Fix:
Cleared Exhaust Pipe
 
Problem Description:
The engine would crank over, fire for 2 to 3 seconds, not start and then make a hissing sound from under the vehicle. It was found that the hissing sound was coming from the muffler weep hole. The vehicle was parked backwards during a blizzard so the engine compartment would not fill with snow. The engine was started the next morning and let run for 45 minutes then shut off and left to sit for the rest of the day. What happened was the tailpipe filled with snow the previous evening and when the engine was left running for those 45 minutes the next morning, the snow thawed and water filled up the lower curve in the tailpipe. Later that day it froze and restricted the exhaust system. A propane torch was used to heat the curve in the tailpipe. The engine was started and the accelerator pedal held down to the floor for a short time to help clear any remaining ice and water out of the exhaust system. The exhaust system is no longer restricted and the engine starts and runs fine.
