DTC P0617 STARTER RELAY CIRCUIT HIGH

Transcription

1 0534 DTC P067 STARTER RELAY CIRCUIT HIGH 05DJY0 MONITOR DESCRIPTION While the engine is being cranked, the battery positive voltage is applied to terminal STA of the ECM. If the ECM detects the starter control signal (STA) while the vehicle is driving, it will conclude that there is a fault in the starter control circuit. The ECM will turn on the MIL and a DTC is set. DTC No. DTC Detection Condition Trouble Area P067 When conditions, and are met when the battery (+) voltage 0.5 V or more is applied to ECM for 0 sec: Vehicle speed greater than mph (0 km/h) Engine revolution greater than,000 rpm STA signal ON Short in Park/Neutral position switch circuit Park/Neutral position switch (A/T) Clutch start switch (M/T) ECM MONITOR STRATEGY Related DTCs P067 Starter signal error Required sensors/components Frequency of operation Duration MIL operation Sequence of operation Continuous 0 sec Immediately None TYPICAL ENALI CONDITIONS Item The monitor will run whenever the following DTCs are not present Main sensors Related sensors Minimum Specification Starter signal Vehicle speed sensor, engine speed sensor Maximum See List of Disable a Monitor table (On page 054) attery voltage 0.5 V Vehicle speed.4 mph (0 km/h) Engine speed,000 rpm TYPICAL MALFUNCTION THRESHOLDS Starer signal Detection Criteria Threshold ON (at more than.4 mph (0 km/h) and more than,000 rpm ) 394

3 0536 INSPECTION PROCEDURE HINT: This DTC chart is on the premise that the engine is cranked normally. If the engine is not cranked, proceed to the problem symptoms table on page 054. Read freeze frame data using the hand held tester or the OD II scan tool. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the airfuel ratio was lean or rich, etc. at the time of the malfunction. READ VALUE OF HANDHELD TESTER OR OD II SCAN TOOL(STARTER Connect the handheld tester or the OD II scan tool to the DLC3. Turn the ignition switch ON and push the handheld tester or the OD II scan tool main switch ON. Select the item DIAGNOSIS / ENHANCED OD II / DATA LIST / ALL / STARTER SIG and read the value displayed the handheld tester or the OD II scan tool. Ignition switch position ON START REPLACE ECM (See page 07) INSPECT PARK/NEUTRAL POSITION SWITCH OR CLUTCH START SWITCH A3 Park/Neutral Position Switch A7933 Inspect the park/neutral position switch. (A/T) () Disconnect the A3 park/neutral position switch connector. () Measure the resistance between each terminal shown below when the shift lever is moved to each range.

4 0537 C mm ( in) ON OFF A859 Inspect the clutch start switch. (M/T) () Disconnect the C8 clutch start switch connector. () Measure the resistance between terminals when the switch ON and OFF. Standard: Switch Position Tester Connection Specified Condition ON (pushed) elow Ω OFF (free) 0 kω or higher (3) Reconnect the clutch start switch connector. REPLACE PARK/NEUTRAL POSITION SWITCH OR CLUTCH START SWITCH (GO TO NEXT STEP 3 AFTER THE REPLACEMENT) 3 READ VALUE OF HANDHELD TESTER OR OD II SCAN TOOL(STARTER Connect the handheld tester or the OD II scan tool to the DLC3. Turn the ignition switch ON and push the handheld tester or the OD II scan tool main switch ON. Select the item DIAGNOSIS / ENHANCED OD II / DATA LIST / ALL / STARTER SIG and read the value displayed the handheld tester or the OD II scan tool. Ignition Switch Position ON START SYSTEM 4 INSPECT IGNITION OR STARTER SWITCH ASSY I0 Measure the resistance between the connector terminals shown in the chart below. Switch Position Tester Connection Specified Condition LOCK All Terminals 0 kω or higher ACC 3 elow Ω ON, 3, 3, 56 elow Ω START 45, 46, 56, elow Ω Ignition Switch REPLACE IGNITION OR STARTER SWITCH ASSY 397

5 READ VALUE OF HANDHELD TESTER OR OD II SCAN TOOL(STARTER Connect the handheld tester or the OD II scan tool to the DLC3. Turn the ignition switch ON and push the handheld tester or the OD II scan tool main switch ON. Select the item DIAGNOSIS / ENHANCED OD II / DATA LIST / ALL / STARTER SIG and read the value displayed the handheld tester or the OD II scan tool.
