C0090

C0090 - RIGHT REAR ABS SOLENOID #1 CIRCUIT MALFUNCTION





The UHFB supplies the solenoid circuits with battery voltage when the ignition is in run. The ABS Control Module (EBTCM) controls valve function by grounding the solenoid circuit when necessary.
#1 solenoids are outlet valves.

DTC PARAMETERS
DTC will set if the ABS control module detects an open, short to ground or short to voltage on the solenoid circuit(s) inside the control module.
When DTC C0090 sets:
^ The ABS telltale will be on.
^ The red BRAKE telltale will be On.
^ The ABS control module will disable ABS.
Dynamic Rear Proportioning (DRP) will only be functional on one rear wheel. If a LR solenoid or LR wheel speed DTC sets with DTC C0080, then DRP is disabled.

DIAGNOSTIC AIDS
The ABS control module must be replaced.
