BASIC DIAGNOSTICS PROCEDURE
CAUTION: Remove foreign matter (dust, water, etc.) from the ABS Control Module And Hydraulic Control Unit (ABSCM&H/U) connector during removal and installation.
NOTE:
- To check harness for broken wires or short circuits, shake it while holding it or the connector.
- When ABS warning light illuminates, read and record trouble code indicated by ABS warning light.
CHECK LIST FOR INTERVIEW
Check The Following Items About The Vehicle's State.
1. THE STATE OF THE ABS WARNING LIGHT
2. SYMPTOMS
3. CONDITIONS UNDER WHICH TROUBLE OCCURS
INSPECTION MODE
Reproduce the condition under which the problem has occurred as much as possible.
Drive the vehicle at a speed more than 40 km/in (25 MPH) for at least one minute.
TROUBLE CODES
When on-board diagnosis of the ABS control module detects a problem, the information (up to a maximum of three) will be stored in the EEPROM as a trouble code. When there are more than three, the most recent three will be stored. (Stored codes will stay in memory until they are cleared.)
Calling Up a Trouble Code
1. Take out diagnosis connector from side of driver's seat heater unit.
2. Turn ignition switch OFF.
3. Connect diagnosis connector terminal 6 to diagnosis terminal.
4. Turn ignition switch ON.
5. ABS warning light is set in the diagnostic mode and blinks to identify trouble code.
6. After the start code (11) is shown, the trouble codes will be shown in order of the last information first. These repeat for a maximum of 5 minutes.
NOTE: When there are no trouble codes in memory, only the start code (11) is shown.
Clearing Memory
1. After calling up a trouble code, disconnect diagnosis connector terminal 6 from diagnosis terminal.
2. Repeat 3 times within approximately 12 seconds; connecting and disconnecting terminal 6 and diagnosis terminal for at least 0.5 seconds each time.
NOTE: After diagnostics is completed, make sure to clear memory. Make sure only start code (11) is shown after memory is cleared.
CAUTION: Remove foreign matter (dust, water, etc.) from the ABS Control Module And Hydraulic Control Unit (ABSCM&H/U) connector during removal and installation.
NOTE:
- To check harness for broken wires or short circuits, shake it while holding it or the connector.
- When ABS warning light illuminates, read and record trouble code indicated by ABS warning light.
