between components 120 and 1550.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for + 12 V after ignition feed on connection3JAC of component 1074.
Measure the resistance of the thermoplunger, component code 1074.
Replace the thermoplunger, component code 1074 if the resistance is greater than 2 Ω.
Replace the water heater interface unit if necessary.
Using a test light, check that the water heater interface unit is properly earthed on connection 3JAB between
components 120 and 1550.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
