DTC 1

Problem Code 1: Hydraulic Controlled Components.

CAUTION: Use only the digital multimeter to check the system.

NOTE: The LED does not blink when the following failures occur.
- The contact points of the motor relay remain closed (the motor runs continuously even after the ignition key is removed).
- YEL/RED wire is shorted or the control unit is internally shorted (the motor stops when the ignition switch is turned off).

Pre-test steps:
- Check ABS MAIN RELAY (40A) Fuse.
- Check all ABS hoses and pipes (low and high pressure) for signs of leaking, bending or kinking.
- Check reservoir fluid level of the modulator, and if necessary, fill to the MAX level.
