No. TROUBLESHOOTING ITEM ACTION
1 Fuel odor•Inspect the water heater system in the vehicle fuel
system.
•Inspect the fuel line for leakage, kinks, or blockage.
•If normal, there is an internal water heater leak.
—Replace the water heater unit.
2 The heater does not achieve full load operation•Replace the water heater unit.
3 Continuous white smoke during combustion operation•Replace the water heater unit.
4 Loss of coolant (leakage). Heater develops smoke during
combustion operation; smell of exhaust fumes extremely
sweet•Inspect the coolant hose for leakage, kinks,
looseness, and loose hose clamps.
•If normal, there is an internal water heater leak.
—Replace the water heater unit.
5 Loss of fuel (leakage)•Inspect the water heater system integration in the
vehicle’s fuel system.
•Inspect the fuel line connections for leakage.
•If normal, there is an internal water heater leak.
—Replace the water heater unit.
6 The water heater unit does not communicate with the SST
(WDS or equivalent)•Refer to section T, ON-BOARD DIAGNOSTIC
[MULTIPLEX COMMUNICATION SYSTEM].
