ISC continuity: ∞ Ω (Infinity)
(Terminal – Ground)
4) If OK, then measure the ISC resistance
(between Br/B, G/B, Y/B and B/Y wires).
ISC resistance: Approx. 6.5 Ω
Is the resistance OK?
•Br/B, G/B, Y/B and B/Y wire open or
shorted to ground, or poor 28, 39,
40 and 41 connection
• If wire and connection are OK,
intermittent trouble or faulty ECU.
YES
• Recheck each terminal and wire
harness for open circuit and poor
connection.
• Replace the ECU with a known
good one, and inspect it again.
• Loose or poor contacts on the ECU
NO coupler
• Replace new ISC (throttle body).
5) After repairing the trouble, clear the DTC
using Diagnosis tool.
• Measure the resistance between A-D and B-C
as below
• The standard are all follow 50.5±0.5Ω.
