Service Codes Summary
Service Codes Summary (continued)
4 Flashing LIGHTs or
CHECK TIRES Flashing
Code No.
Causes (numbered in order of likely occurrence)
Tire Leak (Imbalance)
44, 45
TIRES IMBALANCED (System only checks pressures on given channel): Pressure
check indicates a tire on the given channel may be significantly lower than other tires
on same channel. RUN FLAT will override this fault.
1) Significant tire pressure loss (i.e. overnight leakdown)
2) Significant tire damage or leaks
3) Leaking lines or seals
4) Contaminated wheel valve filters
5) Restricted tire valve stem
6) Faulty wheel valve (leaking back through QRV)
7) Kinked or restricted control lines
Tire Leak (Confirm)
41, 42
CONFIRMATION FAILURE (System disables given channel): Given channel fails to
confirm 10 times in a row.
RUN FLAT will override this fault.
1) Damaged tire or tire leakage
2) Leaking hose between wheel valve and tire
3) Faulty wheel valve (leaking back through QRV)
4) Restricted air passage between QRV and wheel valve
2 Terrain Lights on
Solid or DDM –
Dashes "--"
Code No.
Causes (numbered in order of likely occurrence)
Between Modes
23, 24
SLOW INFLATE (Channel only checks pressures): Given channel takes too long(> 40
minutes) in active inflate (pressure switch closed) to achieve requested mode.
Repair and request pressure check to clear (any mode button or run flat).
1) Insufficient air supply
2) Contaminated wheel valve filters
3) Kinked, plugged, or leaking lines
SLOW DEFLATE (Channel only checks pressures): Given channel takes too long in
active deflate (> 20 minutes) to achieve requested mode.
Repair and request pressure check to clear (any mode button or run flat).
1) Contaminated wheel valve filters
2) Restricted tire valve stem
3) Leaking upper control lines
4) Faulty PCU relief valve
5) Restricted QRV exhaust
6) Restricted PCU vent line
