VAH, VHD, VN
FSB 373-022, Engine Harness Repair
(December 2015)
The engine harness on VOLVO D11 US2015 engines built between March 1, 2015 and
August 31, 2015 may be making contact with the air compressor head and rubbing through.
When diagnostic trouble codes (DTC) P0201 to P0206 FMI 13 are logging, look in this area
first. If this is found to be the root cause of the DTC, it is recommended that the harness be
repaired using a splice kit. On reassembly, protect and support the harness in this area.
