Refer to "55.Transmission Control 5A.Troubleshooting(AWR6B45) diagnostic system check-transmission controls".
1) Connect the scan tool.
2) Turn OFF the ignition switch for 30 seconds or more.
3) Turn ON the ignition switch.
4) Observe the DTC information with a scan tool. Is a DTC set?
Yes
=>Go to Shift solenoid (SL) control circuit voltage check.
No
Go to Intermittent conditions of automatic transmission.
Refer to "206.Transmission, Transaxle 19D.Symptom(AWR6B45) Intermittent conditions of automatic transmission".
1) Turn OFF the ignition switch.
2) Disconnect the transmission internal harness (E42).
3) Connect a test lamp between the shift solenoid (SL) control circuit (pin 1 of E42) of the transmission internal harness and the body ground.
Refer to "LHD Automatic Transmission" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Automatic Transmission" in the ETM (wiring diagram). (Open using the ETM viewer.).
4) Turn ON the ignition switch. Does the test lamp illuminate and then turn OFF?
Note
Yes
=>Go to Inspection of transmission internal harness connector.
No
=>Go to Inspection for open circuit and short circuit in shift solenoid (SL) control circuit.
1) Inspect the shift solenoid (SL) control circuit between the TCM (pin 28 of E5) and the transmission internal harness (pin 1 of E42) for the following. Is the result normal?
Refer to "LHD Automatic Transmission" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Automatic Transmission" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
=>Go to TCM harness connector inspection.
No
Repair the circuit as necessary.
1) Inspect for poor connections at the transmission internal harness connector (pin 1 of E42). Is the result normal?
Refer to "LHD Automatic Transmission" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Automatic Transmission" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
=>Go to Inspection of transmission internal harness.
No
Repair the connections as necessary.
