Harness (MB991952) to the wiring harness-side connector.
2. Turn the ignition switch to the "ON" position.
3. Measure the voltage between terminal 11 and ground. It should be
a
pproximatel
y 12 volts
(batter
y positive volta
ge). NOTE: Do not connect special tool ABS Check Harness
(MB991952) to the TCL/ASC-ECU.

Q: Is TCL/ASC-ECU connector A-32 damaged?
YES: Repair or replace the damaged component(s). Then go to Step 8.
NO: An open or short circuit may be present in the solenoid valve power
supply circuit. Repair the wiring harness between TCL/ASC-ECU
connector A-32 terminal 11 and fusible link No. 3. Then go to Step 8.
STEP 5. Measure the resistance at TCL/ASC-ECU connector A-32.
1. Disconnect the connector A-32, and connect special tool ABS Check
Harness (MB991952) to the wiring harness-side connector.
2. Measure the resistance between terminal 12 and ground. It should be 2
ohms or less. NOTE: Do not connect special tool ABS Check Harness
(MB991952) to the TCL/ASC-ECU.

CIRCUIT OPERATION The meter-ECU detects the brake fluid level switch ON/OFF and controls the brake
warning light ON/OFF.
The TCL/ASC-ECU and the meter-ECU are connected each other via a CAN bus
line, and the meter-ECU informs the TCL/ASC-ECU whether the brake fluid level
switch is turned on or off. ABS DTC SET CONDITIONS This DTC is set when all of the following cases are met.
When the amount of the brake fluid is less than lower limit. Vehicle speed is 15 km/h or more
TROUBLESHOOTING HINTS (The most likely causes for this DTC is to set are:)
Current trouble
Brake fluid is not filled Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU) Malfunction of the combination meter (integrated with meter ECU)
Past trouble
Carry out diagnosis with particular emphasis on connector(s) or wiring harness
between the combination meter circuit (terminal 7) to the brake fluid level
switch or parking brake switch. For diagnosis procedures, refer to HOW TO TREAT PAST TROUBLE
).
