Retrieving Diagnostic Trouble Codes

1999 Toyota Camry XLE, 2.2 GSECTION Retrieving Diagnostic Trouble Codes
NOTE: Speed sensor diagnostics and code retrieval use different DLC terminals with short pin connected. If a speed sensor or speed sensor circuit problem is suspected, see SPEED SENSOR DIAGNOSTICS .
  1. Ensure battery voltage is about 12 volts. Turn ignition on. ABS warning light should come on, then go out after 3 seconds. If warning light does not come on, check fuse, bulb, and wiring harness.
  2. With ignition on, connect jumper wire between terminals Tc and E1 of DLC1 or DLC2 on 1999 models, or Tc and E1 of DLC1 or Tc and CG of DLC3 on 2000 models. See Fig 1-Fig 2 . If a malfunction is detected, 4 seconds will elapse, then ABS warning light will begin to flash a 2-digit Diagnostic Trouble Code (DTC). First series of flashes indicates first digit of DTC. After a 1.5-second pause, second series of flashes indicates second digit of DTC.
  3. If 2 or more DTCs are stored, there will be a 2.5-second pause between each DTC. After all DTCs are displayed, a 4-second pause will occur, then all DTCs will repeat. If ABS system is functioning properly, ABS light will flash 2 times every second. For DTC definitions, see DTC DEFINITIONS . After replacing or repairing malfunctioning components, clear DTCs.
