MANUAL TRANSMISSION AND DIFFERENTIAL (DIAGNOSTICS)
3. General Description
A: CAUTION
The airbag system wiring harness is routed near the DCCD control module.
CAUTION:
• Airbag system wiring harnesses and connectors are yellow. Do not use an electric test equipment
to check these circuits.
• Be careful not to damage the airbag system wiring harness when performing diagnostics or repair
of the DCCD control module.
• When measuring the voltage and resistance of each control module 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. Also, do not insert
the pin more than 5 mm (0.2 in) into the part.
B: INSPECTION
1. POWER SUPPLY
1) Measure the battery voltage and specific gravity of the electrolyte.
Standard voltage: 12 V or more
Specific gravity: 1.260 or more
2) Check the fuse condition.
3) Check the connecting condition of harness and harness connector.
