- Is the resistance greater than 10,000 ohms?
  1. Yes : GO to O2.
  2. No : INSTALL a new Advance Trac®/IVD switch. REFER to TRACTION CONTROL ACTUATOR in this section. TEST the system for normal operation.

O2 - CHECK CIRCUIT 8-CF54 (WH/VT) FOR A SHORT TO POWER
- Key in OFF position.
- Disconnect: ABS Module C135.
- Key in ON position.
