2. Fault code 1 (4–2)
3. Fault code 2 (1)
4. Fault code 3 (7–2)

• A ABS warning light on for 1 second
• B 2 second pause

1. Disconnect the service check connector (2P) from the connector cover located under dash of the passenger's seat side. Connect the two terminals of the service check connector with a link wire.
2. Turn the ignition switch on, but do not start the engine.
3. Record the flashing frequency from the ABS indicator light.
   The frequency of flashes indicates the diagnostic trouble code (DTC).

CAUTION: Before starting the engine, disconnect the link wire from the service check connector, otherwise the Malfunction Indicator Lamp (MIL) will stay on with the engine running.

1. ABS indicator light
2. Service check connector (2P)
3. Jumper wire

Note:

• The ABS control unit can indicate three DTCs (one, two or three problems).
• If the ABS indicator light does not illuminate, see Troubleshooting of ABS Indicator Light Circuit.
• If you miscount the frequency of flashes, turn the ignition switch off then on to cycle the ABS indicator light again.
• After the repair is completed, disconnect the ABS B2 (15 A) fuse in the under-hood ABS fuse/relay box for at least three seconds to erase the ABS control unit's memory. Then turn the ignition key on again and recheck.
• The memory is erased if the connector is disconnected from the ABS control unit or the ABS control unit is removed from the body.
• After recording the DTC (if applicable), refer to the Symptom-to-System Chart.
