FAN CONTROL RELAY CONTINUITY CHART

IDLE-UP OPERATION CHECK 1. Before inspection and adjustment, set vehicle in the following condition:
Engine coolant temperature: 80 - 90 °C (176.0 - 194.0 °F) Lights, electric cooling fan and accessories: OFF Transmission: Neutral ("N" or "P" position) Steering wheel: Straightforward
2. Check whether or not the idle speed is the standard value.
Refer to
CURB IDLE SPEED CHECK
.
Standard value: 680 +/- 50 r/min

3. Turn on the air conditioning switch and the blower speed selection dial. Engine
idling speed should be within the standard value:
Standard value

At low pressure: 680 +/- 50 r/min

At middle pressure: 730 +/- 50 r/min

At high pressure: 750 +/- 50 r/min

Traction Control, Active Skid Control System - Endeavor
GENERAL INFORMATION Traction Control/Active Skid Control System (TCL/ASC) is available for AWD
models as optional equipment.
The Traction Control/Active Skid Control System is a combination system of
active skid control system and traction control system. The active skid control
system avoids a dangerous vehicle attitude by limiting the engine output and
braking a set of wheels (front left and right rear, or right front and left rear)
according to driving conditions. The traction control system prevents wheel
spinning at vehicle start. Fail-safe function ensures safety is maintained Diagnostic function provides improved serviceability To shorten the lines and enhance data transmission reliability, communication
with other ECU is
performed over a CAN
(Controller Area Network
).

DTC U1073: BUS OFF TROUBLE JUDGMENT This code is stored when the TCL/ASC-ECU has ceased the CAN communication
(bus off). Then, if a penalty mode is entered after approximately five minutes,
regular data transmission will be cancelled. TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU)
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A
STEP 1. Using scan tool MB991958, diagnose the CAN bus line. CAUTION:
If DTC U1073 is set in the TCL/ASC-ECU, always
diagnose the CAN main bus line. If there is any
fault in the CAN bus lines, an incorrect DTC may
be set. Whenever the ECU is replaced, ensure that the
communication circuit is normal.
CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.
