DTC C1345: BRAKE FLUID LEVEL INSUFFICIENT
2004 Mitsubishi Endeavor LS
2004 BRAKES Traction Control, Active Skid Control System - Endeavor

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
).
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool
(MUT-III Sub Assembl
y) this diagnosis, diagnose the CAN bus lines.

go to Step 12.
STEP 7. Check intermediate connector C-31, grounding connector A-18,
brake fluid level switch connector A-04, joint connector C-04, combination
meter connector C-102 and parking brake switch connector C-34 for
loose, corroded or damaged terminals, or terminals pushed back in the
