DIAGNOSIS SYSTEM INDICATOR CHECK
When the ignition switch is turned on, check that the ABS warning light goes on for 3 seconds.

HINT: If the indicator check result is not normal, proceed to troubleshooting for the combination meter section.






DIAGNOSTIC CODE CHECK
1. Turn the ignition switch to ON.
2. Disconnect the Short Pin from check connector.






3. Using SST, connect terminals Tc and E1 of TDCL or check connector.
4. Read the diagnostic code from the ABS warning light on the combination meter.

HINT: If no code appears, inspect the diagnostic circuit.






As an example, the blinking patterns for normal code and codes 11 and 21 are shown on the left.
5. Codes are explained below.
6. After completing the check, disconnect terminals Tc and E1, and turn off the display.
If two or more malfunctions are indicated at the same time, the lowest numbered diagnostic code will be displayed first.











DIAGNOSTIC CODE CLEARANCE Testing and Inspection
1. Using SST, connect terminals Tc and E1 of TDCL or check connector. SST 09843-18020

2. IG switch ON.
3. Clear the diagnostic codes stored in ECU by depressing the brake pedal 8 or more times within 3 seconds.
4. Check that the warning light shows the normal code.
5. Remove the SST from the terminals of TDCL or check connector.
6. Connect the Short Pin to check connector.






DIAGNOSTIC CODE CHART
If a malfunction code is displayed during the diagnostic code check, check the circuit listed for that code, the table below and proceed to the page given.






SPEED SENSOR SIGNAL CHECK
1. Turn the ignition switch to OFF.
2. Using SST, connect terminals Tc and E1 of check connector. SST 09843-18020
3. Start the engine.






4. Check that the ABS warning light blinks.

HINT: If the ABS warning light does not blink, inspect the ABS warning light circuit.

5. Drive vehicle straight forward.

HINT: Drive vehicle faster than 80 km/h (50 mph) for several seconds.

6. Stop the vehicle.
7. Using SST, connect terminals Tc and E1 of check connector. SST 09843-18020

8. Read the number of blinks of the ABS warning light.

HINT:See the list of diagnosis codes shown below.

If every sensor is normal, a normal code is output. (A cycle of 0.25 sec. on and 0.25 sec. OFF is repeated)
If two or more malfunctions are indicated at the same time, the lowest numbered code will be displayed first.






9. After performing the check, disconnect terminals Tc and E1, Tc and E1 of check connector, and ignition switch turned off.
