TEST STEP
ACTION TO TAKE
S1 CHECK PRE-HEAT FOR CORRECT CONDITIONS
•
Key OFF.
Yes =
GO to S2.
•
Power Control Station (PCS) in ACTIVE mode.
•
Vehicle Plugged in.
No =
CORRECT the conditions.
•
Outside ambient temperature <18
°
C (64
°
F)
•
Are the conditions acceptable?
S2 CHECK PRE-HEAT SWITCH
•
Key OFF.
Yes =
GO to S3.
•
Depress pre-heat switch.
•
Does the bulb illuminate?
No =
REPAIR pre-heat switch
and/or circuit(s).
S3 CHECK CIRCUIT X(LG/BK) FOR POWER
•
Key OFF.
Yes =
GO to S4.
•
Disconnect pre-heat switch C262, and measure the voltage between
circuit X(LG/BK) and ground.
•
Is the voltage greater than 0 volts?
No =
REPAIR the circuit.
S4 CHECK THE PRE-HEAT SWITCH
•
Key OFF.
Yes =
GO to S5.
•
Depress the button.
•
Check circuit X(LG/BK) and circuit W(RD/LG).
No =
INSTALL a new switch.
•
Is the resistance less than 3 ohms?
S5 CHECK CIRCUIT W(RD/LG) FOR POWER
•
Key OFF.
Yes =
GO to S6.
•
Disconnect pre-heat C262 and measure the voltage between circuit
W(RD/LG) and ground.
•
Is the voltage greater than 0 volts?
No =
REPAIR the circuit.
S6 CHECK THE PRE-HEAT INVERTER RELAY
•
Disconnect the pre-heat inverter relay C135.
Yes =
GO to S7.
•
Carry out the component test on the pre-heat inverter relay. Refer to the
wiring diagrams section for component testing.
•
Is the pre-heat relay OK?
No =
INSTALL a new relay.
S7 CHECK CIRCUIT Y(WH) POWER
•
Key OFF.
Yes =
GO to S8.
•
Depress the pre-heat switch button.
•
Is the voltage greater than 0 volts?
No =
REPAIR the circuit.
S8 CHECK CIRCUIT Y(BK) FOR POWER
•
Key OFF.
Yes =
INSTALL a new Interface
•
Disconnect the Interface Adapter Assembly C1945 and measure the
Adapter Assembly (IAA).
voltage between Y(BK) and ground.
•
Is the voltage greater than 0 volts?
No =
REPAIR the circuit.
