PGM-FI SYSTEM
5. MAP Sensor Output Line Open Circuit
Inspection
Check for continuity between the ECM test harness
and sensor unit 5P (Black) connector [1] of the wire
harness side.
Is there continuity?
YES – Replace the ECM/PCM with a known good
one, and recheck.
NO – Open circuit in the Violet/red wire
MIL 7 BLINKS (ECT SENSOR)
• NC700X/XA/S/SA:
Before starting the inspection, check for loose or
poor contact on the ECT sensor 2P connector and
ECM 33P (Black) connector, then recheck the MIL
blinking.
• NC700XD/SD:
Before starting the inspection, check for loose or
poor contact on the ECT sensor 2P connector and
PCM 33P (Gray) connector, then recheck the MIL
blinking.
• If the ECM/PCM is replaced, perform the following:
– Key Registration Procedure (page 23-6)
– Clutch Initialize Learning Procedure (NC700XD/
SD) (page 12-120)
1. ECT Sensor Output Voltage Inspection
Connect the ECM test harness to the ECM/PCM
33P connector(s).
– NC700X/XA/S/SA (page 4-13)
– NC700XD/SD (page 4-14)
Turn the ignition switch ON and engine stop switch
"".
Measure the voltage at the ECM test harness
terminals.
Is the voltage within 2.7 – 3.1 V (20°C/68°F)?
YES – Intermittent failure
NO – GO TO STEP 2.
Connection:
NC700X/XA/S/SA:
32 – Violet/red
NC700XD/SD:
B32 – Violet/red
Connection:
NC700X/XA/S/SA:
20 (+) – 22 (–)
NC700XD/SD:
B20 (+) – B22 (–)
Standard: 2.7 – 3.1 V (20°C/68°F)
