GENERAL DESCRIPTION

3. General Description

A: CAUTION

• Supplemental Restraint System “Airbag”
Airbag system wiring harness is routed near the
transmission control module (TCM).

CAUTION:
• All airbag system wiring harness and con-
nectors are colored yellow. Do not use electri-
cal test equipment on these circuit.
• Be careful not to damage airbag system wir-
ing harness when performing diagnostics and
servicing the TCM.
• Measurement
When measuring voltage and resistance of the
ECM, TCM or each sensor, use a tapered pin with
a diameter of less than 0.64 mm (0.025 in) in order
to avoid poor contact. Do not insert the pin more
than 0.65 mm (0.0256 in).

B: INSPECTION

1. BATTERY

Measure battery voltage and specific gravity of
electrolyte.

Standard voltage: 12 V or more

Specific gravity: Above 1.260

2. TRANSMISSION GROUND

Make sure that the ground terminal bolt is tightened
securely.
• Chassis side

Tightening torque:

13 N·m (1.3 kgf-m, 9.4 ft-lb)

3. ATF LEVEL

Make sure that ATF level is in the specification.
<Ref. to AT-30, Automatic Transmission Fluid.>

4. FRONT DIFFERENTIAL OIL LEVEL

Make sure that front differential oil level is in the
specification.
