ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT H-LP LH RELAY
*a | Component without harness connected (H-LP LH Relay) |
(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition |
Specified Condition |
---|---|---|
3 - 5 | Voltage not applied between terminals 1 and 2 |
10 kΩ or higher |
3 - 5 | Voltage applied between terminals 1 and 2 |
Below 1 Ω |
If the result is not as specified, replace the H-LP LH relay.
2. INSPECT H-LP RH RELAY
*a | Component without harness connected (H-LP RH Relay) |
(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition |
Specified Condition |
---|---|---|
3 - 5 | Voltage not applied between terminals 1 and 2 |
10 kΩ or higher |
3 - 5 | Voltage applied between terminals 1 and 2 |
Below 1 Ω |
If the result is not as specified, replace the H-LP RH relay.
3. INSPECT DIM RELAY (w/o Cornering Light)
*a | Component without harness connected (DIM Relay) |
(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition |
Specified Condition |
---|---|---|

10 kΩ or higher |
3 - 5 | Voltage applied between terminals 1 and 2 |
Below 1 Ω |
If the result is not as specified, replace the DIM relay.
4. INSPECT DRL RELAY (w/o Cornering Light)
*a | Component without harness connected (DRL Relay) |
(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition |
Specified Condition |
---|---|---|
3 - 5 | Voltage not applied between terminals 1 and 2 |
10 kΩ or higher |

If the result is not as specified, replace the DRL relay.
Toyota Avalon (XX50) 2019-2022 Service & Repair Manual > Automatic Transaxle System: System Voltage Circuit Short to Ground or Open (P056014). Starter Relay Circuit Short to Battery (P061512). Brake Switch "B" Circuit Short to Battery (P070312)
System Voltage Circuit Short to Ground or Open (P056014) DESCRIPTION The battery supplies electricity to the ECM even when the engine switch is off. This power allows the ECM to store data such as DTC history and freeze frame data. If the battery voltage falls below a minimum level, the stored ECM d ...
