Diagnostic Procedure

DTC C1035:13 (EVP CONTROL UNIT) DIAGNOSTIC PROCEDURE

Step	INSPECTION		Action
1	RECORD SNAPSHOT DATA TO UTILIZE WITH REPEATABILITY VERIFICATION NOTE: Recording can be facilitated using the screen capture function of the PC. Record the snapshot data on the repair order.	-	Go to the next Step.
2	DETERMINE WHETHER MALFUNCTION IS PAST OR PRESENT NOTE: When clearing the DTC, the snapshot data is also cleared at the same time. Snapshot data is recorded if it is not recorded in Step 1. Using the M-MDS, clear the DTC from the EVP control unit. (See CLEARING DTC [EVP CONTROL UNIT] .) Switch the ignition ON (engine off). Using the M-MDS, perform the EVP control unit ODDTC self test. (See DTC INSPECTION [EVP CONTROL UNIT] .) Is the same Pending DTC present?	Yes	Replace the EVP control unit, then go to Step 7. (See EVP CONTROL UNIT REMOVAL/INSTALLATION .)
2		No	Go to the next Step.
3	VERIFY DTC REPEATABILITY Switch the ignition ON (engine off). Access the following EVP control unit PIDs using the M-MDS: VP_PV VPR1_V VPWR Access the simulation item VPS_FBK using the M-MDS. Compare the values of VP_PV and VPWR with the PID VPR1_V verified when the electric vacuum pump was operated by simulation item VPS FBK. Is VP PV within the 90% to 110% VPWR range with PID VPR1 V turned on?	Yes	Go to the next Step.
3		No	Replace the EVP control unit, then go to Step 7. (See EVP CONTROL UNIT REMOVAL/INSTALLATION .)
4	DRIVE VEHICLE THEN VERIFY DTC REPEATABILITY BASED ON SERVICE QUESTIONING RESULTS AND SNAPSHOT DATA Switch the ignition ON (engine off). Access the following EVP control unit PIDs using the M-MDS: VP_PV VPR1_V VPWR Drive the vehicle based on the service questions content and snapshot data driving conditions. Compare the values of VP PV and VPWR with the PID VPR1 V verified when the VPR1 V PID is On. Is VP PV within the 90% to 110% VPWR range?	Yes	Go to the next Step.
4		No	Replace the EVP control unit, then go to Step 7. (See EVP CONTROL UNIT REMOVAL/INSTALLATION .)
5	VERIFY DTC REPEATABILITY AND DETERMINE IF MALFUNCTION CAUSE IS EVP CONTROL UNIT DATA Using the M-MDS, clear the DTC from the EVP control unit. (See CLEARING DTC [EVP CONTROL UNIT] .) Switch the ignition ON (engine off). Using the M-MDS, perform the EVP control unit ODDTC self test. (See DTC INSPECTION [EVP CONTROL UNIT] .) Is the same Pending DTC present?	Yes	Replace the EVP control unit, then go to the next Step. (See EVP CONTROL UNIT REMOVAL/INSTALLATION .)
5		No	DTC troubleshooting completed. Explain to the customer that there are no malfunctions with the vehicle based on the contents of the servicing.
6	VERIFY DTC TROUBLESHOOTING COMPLETED Using the M-MDS, clear the DTC from the EVP control unit. (See CLEARING DTC [EVP CONTROL UNIT] .) Using the M-MDS, perform the EVP control unit DTC inspection (See DTC INSPECTION [EVP CONTROL UNIT] .) Is the same Pending DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the EVP control unit, then go to the next Step. (See EVP CONTROL UNIT REMOVAL/INSTALLATION .)
6		No	Go to the next Step.
7	VERIFY NO DTC IS PRESENT Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [EVP CONTROL UNIT] .)
7	VERIFY NO DTC IS PRESENT Are any DTCs present?	No	DTC troubleshooting completed.
