1.CHECK ECM CONNECTOR.
Check the connecting condition of ECM connector.
Is the ECM connector correctly connected?
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P2530 IGNITION SWITCH RUN POSITION CIRCUIT">Go to Step 2.
Connect the ECM connector correctly.
2.CHECK INPUT VOLTAGE OF ECM.
1) Turn the ignition switch to ON.
2) Measure the voltage between ECM connector and engine ground while wiggling the harness between ECM connector and F/B connector.
Connector & terminal
(B137) No. 2 (+) — Engine ground (−):
Is the voltage 8 V or more all the time?
Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.
NOTE:
In this case, the following items may be the cause of fault.
• Open circuit or short circuit to ground in harness between ECM connector and F/B connector
• Poor contact of fuse (F/B No. 5)
• Poor contact of IG2 relay connector
• Poor contact of IG2 relay
Repair the harness and connector.
NOTE:
In this case, repair the following item:
• Open circuit or short circuit to ground in harness between ECM connector and F/B connector
• Poor contact of fuse (F/B No. 5)
• Poor contact of IG2 relay connector
• Poor contact of IG2 relay
1. OUTLINE OF DIAGNOSIS
Detect instantaneous open in ignition switch input circuit to ECM.
Judge as NG if out of specification.
2. COMPONENT DESCRIPTION
ECM monitors the voltage of the ignition switch input circuit. Judge as ignition switch ON when the voltage is the specified value or more.
3. EXECUTION CONDITION
Secondary Parameters | Execution condition |
Battery voltage | ≥ 10.9 V |
Engine speed | ≥ 500 rpm |
4. GENERAL DRIVING CYCLE
Perform the diagnosis continuously after the enable conditions have been established.
5. DIAGNOSTIC METHOD
Judge as NG when the following conditions are established within the predetermined time.
Malfunction Criteria | Threshold Value |
Number of instantaneous opens in ignition switch input circuit | ≥ 5 time(s) |
Time Needed for Diagnosis: 5000 ms
Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
