This Week’s Winners
On this edition of Fix of The Week: a flooded Infiniti, a touchy cruise control in a Mazda and a corroded wheel bearing hub on a Buick.
2010 Infiniti FX35 – Roger Jordan Garage Inc.
This vehicle would at times crank but not start, and alternatively when not cranking over would make a rapid clicking from the IPDM. The car had codes in various modules and had 19 BCM codes which would come back after clearing. We removed fuse 44 in the IPDM which goes to PCM/BCM and the clicking would stop.
We found that the carpet on the passenger side was wet and the sunroof drain tubes were stopped up. Water had soaked the bulkhead connected next to the BCM—we discovered the floorboard had been wet for 3 months. We dried out the water with a heat gun and cleaned the drains. The vehicle then cranked every time, and codes and clicking cleared up.
2010 Mazda 3 – Granite Auto Service
The vehicle’s cruise wouldn’t engage, or it would only do so intermittently. We charged the battery and re-checked the cruise operation. The car had low battery voltage when it started and canceled the cruise operation for that ignition cycle. We replaced the battery and cruise ran fine.
2011 Buick LaCrosse – Rick’s Auto Service
This customer’s ABS and traction control lights were on in the dash and the scanner gave a “service Stabilitrac” message. We found a code C0045 stored LR WSS, signal erratic. We raised the vehicle on the lift and found the tone ring corroded with a chunk missing from it (rusty snowbird car in Florida). We replaced the wheel bearing hub assembly and cleared the code, test drove the vehicle and confirmed the fix.
