Test 4B - Electronic Instrument Cluster (EIC) Speedometer/Odometer Failure

NOTE: Perform TEST VER-1A after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. If problem exists in odometer, use DRB-II to select SEQUENTIAL LEGENDS test. If any legends of Electronic Instrument Cluster (EIC) fail to illuminate or illuminate at the same time (test fails), replace EIC. If test passes, go to next step.
  2. Using DRB-II, stop actuation test. Raise vehicle on hoist and start engine. Place gear selector in Drive (1st gear on manual transmission). Using DRB-II, read Vehicle Speed Sensor (VSS) signal.
  3. If VSS signal does not increase smoothly with acceleration, see appropriate ELECTRONIC INSTRUMENT PANELS article in the ACCESSORIES/SAFETY EQUIPMENT Section. If VSS signal increases smoothly with acceleration, check if problem is with odometer only.
  4. If problem is not with odometer only, replace EIC. If problem is with odometer only, replace body controller.
