Check the supply to thermoplunger 1:
– Disconnect the connector of component 898.
– Connect a test light between connection 3JB of component 898 and a chassis earth.
– Run command AC063 Thermoplunger no. 1 relay.
If the test light comes on correctly, measure the thermoplunger resistance between the connection 3JA of
component 898 and a chassis earth.
If the resistance is greater than 2Ω, replace thermoplunger 1.
If the test light does not come on, check the continuity and insulation of the following connection:
– Connection code 3JB between components 1550 and 898.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the earthing on the additional heater interface unit:
– Disconnect the connector of component 1550.
– Connect a test light between connections 3JA and BP27 of component 1550.
– Run command AC063 Thermoplunger no. 1 relay.
If the test light comes on correctly, replace the additional heater interface unit.
If the test light does not come on, check the continuity and insulation from + 12 V of the following connection:
– Connection code 3JA between components 120 and 1550.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

Reminder of computer operating voltage: 6 V < operating voltage < 16.5 V
Using a voltmeter, take a reading of the battery voltage at its terminals.
– Compare the voltage obtained with the value displayed on the diagnostic tool PR074 Battery voltage.
If it there is no difference (less than 1 V):
Recharge and test the battery and replace it if it is defective.
Next check the charge circuit.
If there is a difference (greater than 1 V):
– Check the tightness and the condition of the battery terminals.
– Using the appropriate wiring diagram:
Check the continuity and absence of interference resistance on the following connections:
– Connection code 3FB between components 597 and 120.
– Connection code AP29 between components 597 and 120.
– Connection code NT between components NT and 120.
(Check the four NT connections)
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
