E.C.C. DESCRIPTION (Models with catalyzer) — Idle-up Control
EF & EC-39prose procedureApplies to GA13DS, GA14DS & GA16DS engines with catalyzer. Engine-speed input is from crank angle sensor on models with E.G.R. and from ignition coil on models without E.G.R. Power steering oil pressure switch input applies to models with power steering. Step 3 starter timing: 15 seconds (models with E.G.R.) vs 10 seconds (models without E.G.R.).
GA13DS, GA14DS & GA16DS
Idle-up Control
This system prevents poor battery charging and erratic idling when the following units are operating:
• Headlamps
• Rear defogger
• Radiator fan motor
• Blower motor
• Power steering pump
In this system, the proper fuel is added to keep a constant idle speed when solenoid valve attached to carburetor are in the "ON" position.
Operation
- 1Water temperature: Between −10°C (14°F) and 75°C (167°F). Engine rpm: As shown in Fig. 1.
UEF001 - 2Water temperature: Above 30°C (86°F). At least one switch ON: • Headlamps • Rear defogger • Radiator fan motor • Blower motor • Power steering oil pressure switch (Models with power steering only). Engine rpm: As shown in Fig. 1.
- 3Water temperature: Above 60°C (140°F). Starter switch: ON → OFF. During 15 seconds*1, 10 seconds*2. Engine rpm: As shown in Fig. 1.*1 Models with E.G.R.*2 Models without E.G.R.
