SECTION 10 - DIAGNOSTIC TROUBLE CODES
• Check the valve driver output CR3(24) 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 valve coil connections and wiring for
short to +Vbatt.
• Check the valve coil for correct impedance (refer to
Section 8).
• Check the valve driver output CR3(33) 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
short to +Vbatt.
• Check the valve coil for correct impedance (refer to
Section 8).
• Check the left brake positive driver output CR3(2)
for a short circuit with -Vbatt.
• Check the brake coil for correct impedance (refer to
Section 8).
• If the wiring and the coil are correct, the driver cir-
cuit is damaged : replace the Slave controller.
• The device or its driving circuit is damaged, replace
the controller.
• Check the right brake positive driver output CR2(2)
for a short circuit with -Vbatt.
• Check the brake coil for correct impedance (refer to
Section 8).
• If the wiring and the coil are correct, the driver cir-
cuit is damaged : replace the Master controller.
