Pinpoint Test D : P2535
- D1 RETRIEVE DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition ON.
- Using a diagnostic scan tool, perform PCM self-test.
Is DTC P2535 recorded?
Yes GO to D2 No For all PCM Diagnostic Trouble Codes (DTCs), refer to Powertrain Control Module (PCM) DTC Chart . - D2 CHECK THE CRANK DETECT CIRCUIT FOR A SHORT TO VOLTAGE WITH THE PCM (POWERTRAIN CONTROL MODULE) DISCONNECTED
- Ignition OFF.
- Disconnect PCM C175B.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C175B-42 Ground
Is any voltage present?
Yes GO to D3 No GO to D5 - D3 CHECK THE CRANK DETECT CIRCUIT FOR A SHORT TO VOLTAGE WITH THE IGNITION OFF
- Ignition OFF.
- Measure:
Positive Lead Measurement / Action Negative Lead C175B-42 Ground
Is any voltage present?
Yes GO to D4 No REPAIR the circuit. - D4 CHECK THE CRANK DETECT CIRCUIT FOR A SHORT TO VOLTAGE WITH IGNITION SWITCH DISCONNECTED
- Disconnect C250.
- Measure:
Positive Lead Measurement / Action Negative Lead C175B-42 Ground
Is any voltage present?
Yes REPAIR the circuit. No INSTALL a new ignition switch REFER to Ignition Switch . - D5 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all PCM connectors.
- Repair:
- corrosion (install new connectors or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the PCM connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, Refer to PCM Guided Routine Testing . No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
