  1. Using DRB, read traction control switch state. Depress traction and hold control selection switch on instrument panel. If DRB displays TRAC C SW status change, go to TEST 29B. If DRB does not display a status change, go to next step.
  2. Turn ignition off. Remove traction control system switch from instrument panel. Inspect, clean or repair connector as necessary. Put DRB in ohmmeter mode. Using DRB, check resistance of Black wire at traction control system switch connector terminal No. 1. See Figure. If resistance is more than 5 ohms, repair open in Black wire. Perform TEST VER-1A. If resistance is less than 5 ohms, go to next step.
  3. Turn ignition on. Monitor DRB traction control system switch state. Connect a jumper wire between chassis ground and Red/Yellow wire at traction control system switch connector terminal No. 2. If DRB displays TRAC C SW PRESSED, replace traction control system switch. Perform TEST VER-1A. If DRB does not display TRAC C SW PRESSED, go to next step.
  4. Turn ignition off. Disconnect CAB 37-pin connector. Inspect, clean or repair connector as necessary. Connect jumper wire between chassis ground and Red/Yellow wire at traction control system switch connector terminal No. 2. Using DRB, check resistance of Red/Yellow wire at CAB connector terminal No. 9. If resistance is more than 5 ohms, repair open in Red/Yellow wire. Perform TEST VER-1A. If resistance is less than 5 ohms, go to next step.
  5. Remove CAB from HCU. See Figure. Inspect 14-pin connection. If connection is faulty, repair as necessary. Perform TEST VER-1A. If terminals are backed-out, replace HCU. Perform TEST VER-1A. If connection is okay, replace CAB. Perform TEST VER-1A.
