INSPECTION
PROCEDURE
1. INSPECT SHIFT LOCK CONTROL ECU
HINT:
If the results of the following inspections are as specified but a malfunction has occurred, replace the shift lock control unit assembly.
(a) Inspect wire harness:
(1) Disconnect the shift lock control ECU connector. | |
(2) Measure the voltage according to the value(s) in the table below. Standard Voltage: Tester Connection | Condition | Specified Condition | 5 (IG) - Body ground | Engine switch on (IG) | 11 to 14 V | Engine switch off | Below 1 V | If the result is not as specified, repair or replace the shift lock control ECU wire harness. | | *a | Front view of wire harness connector (to Shift Lock Control ECU) | | |
(3) Measure the resistance according to the value(s) in the table below. Standard Voltage: Tester Connection | Condition | Specified Condition | 4 (STP) - Body ground | Engine switch on (IG), brake pedal depressed | 11 to 14 V | Engine switch on (IG), brake pedal released | Below 1 V | If the result is not as specified, repair or replace the shift lock control ECU wire harness. | | *a | Front view of wire harness connector (to Shift Lock Control ECU) | | |
(4) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | 1 (E) - Body ground | Always | Below 1 Ω | If the result is not as specified, repair or replace the shift lock control ECU wire harness. | | *a | Front view of wire harness connector (to Shift Lock Control ECU) | | |
(b) Inspect shift lock solenoid:
(1) Disconnect the shift lock solenoid connector. | |
(2) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | 4 (P) - 3 (E2) | Shift lever in P | 10 kΩ or higher | Shift lever not in P | Below 1 Ω | If the result is not as specified, replace the shift lock control unit assembly. | | *a | Front view of wire harness connector (to Shift Lock Solenoid) | | |
(3) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | 1 (SLS+) - 2 (SLS-) | Always | 112 Ω | If the result is not as specified, replace the shift lock control unit assembly. | | *a | Front view of wire harness connector (to Shift Lock Solenoid) | | |
2. INSPECT TRANSMISSION CONTROL SWITCH
(a) Disconnect the transmission control switch connector. | |
(b) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | 4 (IG) - 5 (S) | Shift lever in S, "+" or "-" | Below 1 Ω | Shift lever not in S, "+" or "-" | 10 kΩ or higher | 3 (SFTU) - 2 (E) | Shift lever held in "+" (Up-shift) | Below 1 Ω | Shift lever not held in "+" (Up-shift) | 10 kΩ or higher | 1 (SFTD) - 2 (E) | Shift lever held in "-" (Down-shift) | Below 1 Ω | Shift lever not held in "-" (Down-shift) | 10 kΩ or higher | If the result is not as specified, replace the shift lock control unit assembly. | | *a | Component without harness connected (Transmission Control Switch (Transmission Floor Shift Assembly)) | | |
