HINT:
Do not disconnect the shift lock control unit assembly connector.
If the result is not as specified, replace the shift lock control unit assembly.
2. INSPECT TRANSMISSION CONTROL SWITCH
(a) Disconnect the shift lock solenoid 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 | | 1 (SFTD) - 2 (E) | Shift lever held in "-" (Down-shift) | Below 1 Ω | | 3 (SFTU) - 2 (E) | Shift lever held in "+" (Up-shift) | Below 1 Ω | | 4 (IG) - 5 (S) | Shift lever not in S, "+" or "-" | 10 kΩ or higher | | 1 (SFTD) - 2 (E) | Shift lever in S | 10 kΩ or higher | | 3 (SFTU) - 2 (E) | Shift lever in S | 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) | | |
