SECTION 10 - DIAGNOSTIC TROUBLE CODES
• Check the valve driver output CR3(34) for a short
circuit with -Vbatt.
• Check the valve coil connections and wiring for
interruptions.
• Check the valve coil for correct impedance (refer to
Section 8).
• If the wiring is correct, the driver circuit is damaged
: replace the Slave controller.
• Check the valve coil connections and wiring for
interruptions.
• Check the valve coil for correct impedance (refer to
Section 8).
• Replace the Slave controller if the coil and its har-
ness are correct.
• Check the valve coil connections and wiring for
interruptions.
• Check the valve coil for correct impedance (refer to
Section 8).
• Replace the Slave controller if the coil and its har-
ness are correct.
• Check the valve coil connections and wiring for
interruptions.
• Check the valve coil for correct impedance (refer to
Section 8).
• Replace the Slave controller if the coil and its har-
ness are correct.
• Check the following Slave controller driver output
CR3(23) for a short circuit with +Vbatt.
• Check the valve coil for correct impedance (refer to
Section 8).
• If the harness and the coil are correct and if the fault
appears at start up : Replace the Slave controller.
• Check the valve driver output CR3(23) for a short
circuit with -Vbatt.
• If the wiring is correct, the driver circuit is damaged
: replace the Slave controller.
• Check the valve coil connections and wiring for
interruptions.
• Check the valve coil for correct impedance (refer to
Section 8).
• Replace the Slave controller if the coil and its har-
ness are correct.
• Check the following Master controller driver out-
puts for a short circuit with +Vbatt : Beacon
CR2(11), Line Contactor CR2(8).
• Check the line contactor coil for correct impedance
(refer to Section 8).
• If the harness and the devices are correct and if the
fault appears at start up : Replace the Master con-
troller.
